Matrix converter is a direct AC-AC converter topology that directly converts energy from an AC source to an AC load without the need of a bulky and limited lifetime energy storage element. Due to the significant advantages offered by matrix converter, such as adjustable power factor, capability of regeneration and high quality sinusoidal input/output waveforms. Matrix converter has been one of the AC–AC topologies that hasreceived extensive research attention for being an alternative to replace traditional AC-DC-AC converters in the variable voltage and variable frequency AC drive applications. In the present paper an indirect space vector modulated matrix converter is proposed. The basic idea of an indirect modulation scheme is to separately apply SVM to the rectification and inversion stages, before combining their switching states to produce the final gating signals. The paper encompasses development of a laboratory prototype of 230V, 250VA three phase to three phase DSP controlled matrix converter fed induction motor drive. The observations and real time testings have been carried out to evaluate and improve the stability of system under various typical abnormal input voltage conditions
In recent years, studies have been investigated the effectiveness of UPFC and TCSC in increasing power transfer capability. However, the effectiveness of these FACTS devices in increasing power transfer capability when the load is non-linear has not been established in a comparative study yet. This paper will explore the steady-state performance of the UPFC and TCSC as impedance compensation models. The effectiveness of both FACTS devices are investigated when they are installed in multi-machine systems with different non-linear load models. Simulation results demonstrate that, upon installing UPFC, more active and reactive powers are received at the sending end bus for different types of non-linear load models. In addition, both active and reactive powers are more sensitive in changing the modulation index of the converters. Furthermore, both the active and reactive powers are less sensitive to the non-linearity of the load model type. However, active and reactive powers in case of installing TCSC are only sensitive in changing the firing angle (α) when it is between 90º to 110º. Therefore, results from this study clearly encourage the effectiveness of UPFC in comparison to TSCS in terms of increasing power transfer capability applied to non-linear load models.

Improvement in Power Transmission Capacity by Simultaneous AC-DC Transmissiontheijes
Now days in power transmission systems mainly the high voltage three phase AC or HVDC transmission lines for greater efficiency at very long distances are used. In this paper, we have to show the scheme of AC and DC power transmission system which can be developed by converting double circuit ac line into composite AC and DC power transmission line and also comparing simulation results with the simple EHVAC transmission system and HVDC transmission system having six pulses PWM generator. The main object of thesis is to show that by superimposing DC in AC transmission, the capacity of the transmission line can be increased by nearly 70 % of that if only AC is transmitted. In our existing transmission system, long extra high voltage (EHV) AC lines cannot be loaded to their thermal limits in order to keep sufficient margin against transient instability. With the scheme proposed in this project, it is possible to load these lines close to their thermal limits. The conductors are allowed to carry usual ac along with dc superimposed on it, without altering the original line conductors, tower structures, and insulator strings has been presented.
Simulation and Control of PV Based Gird Connected Energy Management System Us...IJMTST Journal
This document summarizes a study on improving droop control for a two-stage photovoltaic (PV) system connected to a grid or operating independently. Droop control is commonly used to relate the terminal parameters of distributed generators to their power output. However, most studies have assumed a fixed DC input source and ignored fluctuations from renewable sources like PV. The proposed improved droop scheme uses STATCOM control structure in both grid-connected and island modes to provide reactive power compensation and mitigate harmonics. It also adapts better to internal PV and external grid fluctuations compared to traditional droop control. Simulation results show the proposed scheme allows maximum PV power output while remaining unaffected by power and voltage/frequency disturbances in grid-connected mode.

The document discusses power flow analysis, which determines the voltage, current, real power, and reactive power at points in an electrical network under normal operating conditions. It provides three key points:
1. Power flow analysis is important for planning, operations, and future expansion of power systems by studying the effects of new loads, generators, or transmission lines.
2. The analysis involves classifying buses as slack, generator, or load buses and formulating the network equations based on the bus admittance matrix.
3. Solving the load flow problem involves determining the complex voltages across all buses given the network configuration and bus demands. This provides critical information for monitoring overloads and voltage deviations.

Power Flow Analysis for Four Buses System by NR Methodijtsrd
Power flow studies provide a systematic mathematical approach for determination of various bus voltages, there phase angle, active and reactive power flows through different branches, generators and loads under steady state condition. In this paper, the purpose of power flow analysis is to determine four bus system power flows. Case studies have been performed on Lawpita Taungoo Kamarnat Hlawga 230kV Line Myanmar . This paper presents a reliable method to meet the requirements by developing a Newton Raphson based load flow calculation program through which control setting of Shunt Compensator can be determined directly. This program computes the voltage magnitude and angle at each bus in a power system under balanced steady state conditions. Real and reactive power flows for all buses, as well as line flow and line losses, are also computed. And then the compensation of shunt capacitor is proposed for load flow analysis and also for overall loss minimization and improvement in system voltage profile.

A generalized switching function-based SVM algorithm of single-phase three-le...IJECEIAES
In this paper, a generalized switching function-based space vector modulation (SVM) algorithm is presented and evaluated to minimize the dc voltage utilization and the ac utility grid current total harmonic distortion. This paper explores the control and modulation techniques of a single-phase three-leg converter with an active power decoupling method, where a generalized SVM algorithm is proposed and evaluated for easy implementation in a digital control platform. The active power decoupling method with the proposed converter can be achieved via dependent control and modulation techniques. The control method is separated into the ac active power control part and the dc power ripple control part, which can maintain a unity power factor at the ac utility grid and reduced the double-frequency ripple power effect on the dc-side. Simulation results validate the performance of the modulation algorithm and its control and demonstrate the feasibility of the proposed power converter, as well as the two mentioned operation modes of the power converter.
This document describes the design, implementation, and testing of an ultracapacitor-based auxiliary energy system (AES) installed in an electric vehicle (EV) to improve efficiency. The AES uses an ultracapacitor bank and buck-boost converter to provide power support to the EV's lead-acid battery pack. Two control strategies for the AES were developed and tested - one based on heuristics and the other using neural networks. Testing showed the AES could reduce costs if it extended the battery life by 50% or more, which is unlikely. The AES was also evaluated for a hypothetical fuel cell-powered EV, where it showed significant cost reductions compared to a fuel cell-only system, especially when using ultracapacitors.

This document summarizes control strategies for different hybrid energy storage systems used in electric vehicles. It classifies strategies into four configurations: fuel cell-battery, battery-ultracapacitor, fuel cell-ultracapacitor, and battery-fuel cell-ultracapacitor. The document provides a comparative analysis of control techniques based on aspects like control parameters, vehicle operation, and performance metrics.

This paper proposes a hybrid series capacitive compensation scheme using a thyristor controlled series capacitor (TCSC) to damp power system oscillations. The scheme uses a single-phase TCSC in one transmission line phase along with fixed capacitors in the other two phases. This creates a phase imbalance that can dampen both power swings and sub-synchronous resonance oscillations. MATLAB simulations show the scheme effectively dampens generator load angle oscillations compared to a fixed compensation scheme following a fault. The hybrid scheme has potential for industrial application as it provides damping benefits while reducing costs versus a full three-phase TCSC installation.

carried out by formulating the mathematical model for the photovoltaic source, MPPT, Motor. System
performance‟s are investigated under different levels of solar insolation.

Power Flow Analysis for Four Buses System by NR Methodijtsrd
Power flow studies provide a systematic mathematical approach for determination of various bus voltages, there phase angle, active and reactive power flows through different branches, generators and loads under steady state condition. In this paper, the purpose of power flow analysis is to determine four bus system power flows. Case studies have been performed on Lawpita Taungoo Kamarnat Hlawga 230kV Line Myanmar . This paper presents a reliable method to meet the requirements by developing a Newton Raphson based load flow calculation program through which control setting of Shunt Compensator can be determined directly. This program computes the voltage magnitude and angle at each bus in a power system under balanced steady state conditions. Real and reactive power flows for all buses, as well as line flow and line losses, are also computed. And then the compensation of shunt capacitor is proposed for load flow analysis and also for overall loss minimization and improvement in system voltage profile.

A generalized switching function-based SVM algorithm of single-phase three-le...IJECEIAES
In this paper, a generalized switching function-based space vector modulation (SVM) algorithm is presented and evaluated to minimize the dc voltage utilization and the ac utility grid current total harmonic distortion. This paper explores the control and modulation techniques of a single-phase three-leg converter with an active power decoupling method, where a generalized SVM algorithm is proposed and evaluated for easy implementation in a digital control platform. The active power decoupling method with the proposed converter can be achieved via dependent control and modulation techniques. The control method is separated into the ac active power control part and the dc power ripple control part, which can maintain a unity power factor at the ac utility grid and reduced the double-frequency ripple power effect on the dc-side. Simulation results validate the performance of the modulation algorithm and its control and demonstrate the feasibility of the proposed power converter, as well as the two mentioned operation modes of the power converter.
This document describes the design, implementation, and testing of an ultracapacitor-based auxiliary energy system (AES) installed in an electric vehicle (EV) to improve efficiency. The AES uses an ultracapacitor bank and buck-boost converter to provide power support to the EV's lead-acid battery pack. Two control strategies for the AES were developed and tested - one based on heuristics and the other using neural networks. Testing showed the AES could reduce costs if it extended the battery life by 50% or more, which is unlikely. The AES was also evaluated for a hypothetical fuel cell-powered EV, where it showed significant cost reductions compared to a fuel cell-only system, especially when using ultracapacitors.

This paper proposes a hybrid series capacitive compensation scheme using a thyristor controlled series capacitor (TCSC) to damp power system oscillations. The scheme uses a single-phase TCSC in one transmission line phase along with fixed capacitors in the other two phases. This creates a phase imbalance that can dampen both power swings and sub-synchronous resonance oscillations. MATLAB simulations show the scheme effectively dampens generator load angle oscillations compared to a fixed compensation scheme following a fault. The hybrid scheme has potential for industrial application as it provides damping benefits while reducing costs versus a full three-phase TCSC installation.

This article presents nonlinear control of wind conversion chain connected to the grid based on a permanent magnet synchronous generator. The control objectives are threefold; i) forcing the generator speed to track a varying reference signal in order to extract the maximum power at different wind speed (MPPT); ii) regulating the rectifier output capacitor voltage; iii) reducing the harmonic and reactive currents injected in the grid. This means that the inverter output current must be sinusoidal and in phase with the AC supply voltage (PFC). To this end, a nonlinear state-feedback control is developed, based on the average nonlinear model of the whole controlled system. This control strategy involves backstepping approach, Lyapunov stability and other tools from theory of linear systems. The proposed state-feedback control strategy is tested by numerical simulation which shows that the developed controller reaches its objectives.

Simulation Model of Hydro Power Plant Using Matlab/Simulink

ABSTRACT
Hydropower has now become the best source of electricity on earth. It is produced due to the energy provided by
moving or falling water. History proves that the cost of this electricity remains constant over the year. Because
of the many advantages, most of the countries now have hydropower as the source of major electricity producer.
The most important advantage of hydropower is that t is green energy, which mean that no air or water pollutants
are produced, also no greenhouse gases like carbon dioxide are produced which makes this source of energy
environment-friendly. It prevents us from the danger of global warming. This paper describes a generalized
model which can be used to simulate a hydro power plant using MATLAB/SIMULINK. The plant consists of
hydro turbine connected to synchronous generator, which is connected to public grid. Simulation of hydro
turbine and synchronous generator can be done using various simulation tools, In this work,
SIMULINK/MATLAB is favored over other tools in modeling the dynamics of a hydro turbine and synchronous
machine. The SIMULINK program in MATLAB is used to obtain a schematic model of the hydro plant by
means of basic function blocks. This approach is pedagogically better than using a compilation of program code
as in other software programs .The library of SIMULINK software programs includes function blocks which can
be linked and edited to model. The main objectives of this model are aimed to achieve some operating modes of
the hydro plant and some operating tests.
Keywords – Hydro power plant, Synchronous machine, Hydro Turbine, Excitation.

INTRODUCTION
This paper describes the dynamic model of
the two main components of hydro power plants, the
synchronous generator and the hydro turbine
governor.
The synchronous machine’s dynamic model
equations in the Laplace domain can be created by
connecting appropriate function blocks. In order to
simulate the detailed transient analysis of the
synchronous machine, addition of new sub-models
is needed to model the operation of various control
functions. These sub-models are used in the
calculation of various values related to the
synchronous machine such as the steady state,
exciter loop, turbine governor model and the
currents.
Detailed mathematical representation of the
hydraulic turbine-penstock also presented in this
paper.. The dynamic performance of the hydraulic
system is studied using time domain and frequency
domain methods. The introduced mathematical
representation of a hydraulic system is including
both turbine-penstock and the governing system.
The primary source for the electrical power
provided by utilities is the kinetic energy of water
which is converted into mechanical energy by the
prime movers. The electrical energy to be supplied
to the end users is then transformed from
mechanical energy by the synchronous generators.
The speed governing system adjusts the generator

speed based on the input signals of the deviations of
both system frequency and interchanged power with
respect to the reference settings. This is to ensure
that the generator operates at or near nominal speed
at all times.
Simulation of the three-phase synchronous
machine and hydro turbines is well documented in
the literature and a digital computer solution can be
performed using various methods. This paper
discusses the use of SIMULINK software of
MATLAB, in the dynamic modeling of the hydro
plant components. The main advantage of
SIMULINK over other programming software is
that, instead of compilation of program code, the
simulation model is built up systematically by
means of basic function blocks. To be able to model
the dynamics of the hydro power plant, dynamic
behavior or differential equations of the
synchronous machine as well as hydro turbine need
to be considered.

SYNCHRONOUS MACHINE MODEL
This section describes a generalized model
which can be used to simulate a three-phase. P-pole,
symmetrical synchronous machine in rotating qd
reference frame.

aim of the d–q model is to eliminate the dependence
of inductances on rotor position. To do so, the
system of coordinates should be attached to the
machine part that has magnetic saliency- the rotor
for synchronous generators.[1]
The d–q model should express both stator
and rotor equations in rotor coordinates, aligned to
rotor d and q axes because, at least in the absence of
magnetic saturation, there is no coupling between
the two axes. The rotor windings f, D, Q are already
aligned along d and q axes.
It is only the stator voltages, VA, VB, VC,
currents IA, IB, IC, and flux linkages ΨA, ΨB, ΨC
that have to be transformed to rotor orthogonal
coordinates. The transformation of coordinates ABC
to d–q-0, known also as the Park transform, valid for
voltages, currents, and flux linkages as well, it is as
follows:

HYDRO TURBINE MODEL
Power system performance is a acted by
dynamic characteristics of hydraulic governorturbines during and following any disturbance, such
as occurrence of a fault, loss of a transmission line
or a rapid change of load. Accurate modeling of
hydraulic governor-turbines is essential to
characterize and diagnose the system response
during an emergency. Simple hydraulic systems
governed by proportional-integral-derivative and
proportional-integral controllers are modeled. This
model examines their transient responses to
disturbances

simulation

Matlab/Simulink.[4]

2.3 TORQUE EQUATION
The equation of motion of the rotor is
obtained by equating the inertia torque to the
accelerating torque, that is:
Fig.3 shows a block diagram of the
hydraulic governor-turbine system connected to a
power system network. The primary source for the
electrical power provided by utilities is the kinetic
energy of water which is converted into mechanical
energy by the prime movers. The electrical energy
to be supplied to the end users is then transformed
from mechanical energy by the synchronous
generators. The speed governing system adjusts the
generator speed based on the input signals of the
deviations of both system frequency and
interchanged power with respect to the reference
settings. This is to ensure that the generator operates
at or near nominal speed at all times. The hydraulic
unit characteristic of a single penstock is:

The principal input to this model is the
output, , from the terminal voltage transducer and
load compensator model. At the summing junction,
terminal voltage transducer output, , is subtracted
from the set point reference,
. The stabilizing
feedback,
, is subtracted, and the power system
stabilizing signal,
, is added to produce an error
voltage. In the steady-state, these last two signals
are zero, leaving only the terminal voltage error
signal. The resulting signal is ampliÞed in the
regulator. The major time constant,
, and gain,

voltage regulators utilize power sources that are
essentially unaffected by brief transients on the
synchronous machine or auxiliaries buses. The time
constants,
and
may be used to model
equivalent time constants inherent in the voltage
regulator; but these time constants are frequently
small enough to be neglected, and provision should
be made for zero input data.[6]
The voltage regulator output,
, is used to
control the exciter, The exciter is represented by the
following transfer function between the exciter
voltage
and the regulator's output
:[6]

A signal derived from field voltage is normally used
to provide excitation system stabilization,

EXCITATION SYSTEM MODEL
An excitation system model is described.
Type DC excitation systems without the exciter's
saturation, which utilize a direct current generator
with a comutmator as the source of excitation
system power.
This model, described by the block
diagram of Fig 4, is used to represent field
controlled dc commutator exciters with continuously
acting voltage regulators.

CONCLUSION
SIMULINK is a powerful software
package for the study of dynamic and nonlinear
systems. Using SIMULINK, the simulation model
can be built up systematically starting from simple
sub-models. The hydro power plant model
developed may be used alone, as in the direct-online starting example presented, or it can be
incorporated in an advanced drive system. Several
tests and operating conditions can be applied on the
model. In this paper a three phase fault case was
shown, many other faults or operating conditions as
over load conditions can be applied and examined
by this model. The author believe that SIMULINK
will soon become an indispensable tool for the
teaching and research of electrical machine drives.
