Load Frequency Control of Multi Area System using Integral-Fuzzy ControllerIJERA Editor
The power system is interconnected to enhance the security and reliability. With large interconnected system, unexpected external disturbances, parameter uncertainties and the model uncertainties make big challenges for stability of system. Load Frequency Control (LFC) deals with the control of real power and frequency of the system. The LFC is used to reduce the transient deviations in the power system. It limits the frequency within limits and controls the tie-line exchange power. Various controllers are used for this purpose. Recently Artificial Intelligence Techniques such as Artificial Neural Network (ANN), fuzzy logic, Genetic Algorithm etc. are used for the designing of controllers. These controllers provide a faster response and are flexible to adjust according to system conditions. In this paper, I have designed integral controller which is conventional method for Load Frequency Control and Artificial Intelligence Technique based Fuzzy Logic controller to deal with the Load Frequency Control Problem for Multi-area System.

Load frequency control is one of the important issues in electrical power system
design/operation and is becoming much more significant recently with increasing size,
changing structure and complexity in interconnected power system. This paper deals with a

Controller when both controllers are applied to three area interconnected Thermal-ThermalHydro. The dynamical response of the load frequency control problem in an interconnected
power system is improved by designing PID controller using Pessen Integral Rule (similar to

LOAD FREQUENCY CONTROL IN TWO AREA NETWORK INCLUDING DGIAEME Publication
Automatic Generation Control (AGC) is associate integral a part of Energy Management
System. This paper deals with the automatic generation control of interconnected multi area grid
network. The first purpose of the AGC is to balance the full system generation against system load
and losses so the specified frequency and power interchange with neighboring systems are
maintained. Any pair between generation and demand causes the system frequency to deviate from
regular worth. So high frequency deviation could result in system collapse. This necessitates
associate correct and quick acting controller to take care of constant nominal frequency. The
limitations of the conventional controls are slow and lack of efficiency in handling system nonlinearity.
This leads to develop a control technique for AGC. In this paper both conventional and
PI viz. Proportional Integral controller approach of automatic generation control has been
examined. PI based AGC has been used for all optimization purposes. System performance has
been evaluated at various disturbances such as, load disturbances, grid disturbances and both load
and grid disturbances. Various responses due to conventional and proposed PI based AGC
controllers have been compared at load disturbances, grid disturbances and both load and grid
disturbances.
Automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary. The balance can be judged by measuring the system frequency; if it is increasing, more power is being generated than used, which causes all the machines in the system to accelerate. If the system frequency is decreasing, more load is on the system than the instantaneous generation can provide, which causes all generators to slow down.

WORKSHOP: Frequency Control Schemes and Frequency Response of Power Systems c...Francisco Gonzalez-Longatt
The frequency of a power system depends on real power balance: generation-demand. During the normal operation of a power system, the frequency is regulated within strict limits by adjusting the electrical supply to meet the demand. If the balance between generation and demand is not reached, the system frequency will change at a rate initially determinate by the total system inertia. The total system inertia comprises the combined inertia of most of spinning generation and load connected to the power system. The contribution of the system inertia of one load or generator depend if the system frequency causes change in its rotational speed and, then, its kinetic energy. Worldwide, electricity generation from renewable energy is increasing rapidly; it is especially true in terms of the increasing of the wind power penetration. This situation arise some issues regarding the system frequency control because wind turbines provide small or even none response to frequency changes. Power electronically controlled and/or power electronically connected generators such as DFIG and FPC wind turbines do not naturally provide inertia response. However inertia response can be emulated by adding a supplementary control signal proportional to the rate of change of frequency, this is named the Synthetic or Artificial Inertia. This approach imposes some challenges about control and protection systems. This workshop is designed to provide a general understanding of the frequency control schemes and frequency response of power systems with the integration of wind power penetration.

Abstract This paper addresses the automatic generation control of deregulated multi area power system including one of the most important renewable energy resource viz. wind power plant. The interconnected two area power system is thermal-hydro system with two GENCOs in thermal area and one GENCO in hydro area. Generation rate constraint (GRC) is considered in all the GENCOs separately. Integral square error technique is used to optimize the gains of various integral controllers. It is seen that system response becomes poorer in terms of peak overshoots and settling time by considering GRC. DISCO participation matrix is chosen on the basis of open market strategy which is continuously changing. So, effect of changing DPM on dynamic responses is studied, following a step load perturbation. It is revealed that there is no effect of changing DPM on system’s dynamic responses. Keywords – Automatic generation control (AGC), deregulated power system, DISCO participation matrix (DPM), wind turbines, generation rate constraint (GRC).

he common control technique for power converter of Doubly Fed
Induction Generator (DFIG) is presented. But there are some disadvantages with this control method like uncertainty about the exact model, behavior of some parameters or unpredictable wind speed and tuning of PI parameters. To overcome the mentioned disadvantages a fuzzy logic control of DFIG wind turbine is presented and is compared with PI controller. To validate the proposed scheme, simulation results are presented, these results showed that the performance of fuzzy control of DFIG is excellent and it improves power quality and stability of wind turbine compared to PI controller. The Fuzzy logic controller is applied to rotor side converter for active power control and voltage regulation of wind turbine. The entire work is carried out in MATLab/Simulink. Different faulty operating conditions are considered to
prove the effective implementation of the proposed control scheme.
4.power quality improvement in dg system using shunt active filterEditorJST
Injection of power generated by the wind turbine system into an electric grid mainly effects the power quality. The performance of this wind turbine and its power quality is determined on the basis of its measurement of power ratings as per IEEE standards. The influence of the wind turbine in the grid system concerning the power quality measurements are the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation. To mitigate the power quality problems this paper proposes the shunt compensator techniques. Here, the proposed system is verified experimentally using both STATCOM and TSC compensators. This control schemes for grid connected wind energy system is simulated using Matlab/Simulink.

Performance analysis and simulation of solar pv wind hybrid energy system wit...THRIKOON G
Wind power is one of the most important kinds of renewable energies. Wind farm as a device which receives this energy needs some special conditions to work properly. The most common type of wind turbine is the variable-speed directly connected to the grid. Faults in the power system can originate the disconnection of wind farms. Dynamic voltage restorer (DVR) is a custom power device used for eliminating voltage sages and swells which is the result of the faults. This paper presents a simulation model of a 12-pulse DVR using photovoltaic (PV) as a mean of providing an alternative energy source for the DVR. Simulations were carried out using the Matlab Simulink. The simulation results proved the capability of PV-based DVR in eliminating voltage sag and swell distributed system. Improving the operation of wind farm as an energy generator and stabilizing its voltage is the main result of this work.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

These perturbations effect to the mismatch in generation of power
system and overall load demand.
But these are the most important parameters of power system that
are needed to be controlled to their nominal values even after the
disturbances
Hear AGC can used to control secondary side.
5. WHAT DOES AGC MEAN?
Process that controls the limits of the frequency and voltage
variations.
The mismatching between the generation and load demand,
If the frequency is swinging.
6. Purpose of AGC
To maintain power balance in the system.
Make sure that system frequency is constant (not change by
load).
To maintain each unit's generation at the most economic
value.
7. Wind power plant
Conventional power plants like thermal, hydro, nuclear etc.
pose a threat to the environment and lead to the global
warming due to harmful gas emissions.
So, it is of great importance to include cleaner sources of
power into the power system like solar power, wind power
etc.
Solar power plant have low energy conversion efficiency and
are more expensive than wind power plants.
8. In wind power plant, Wind speed varies with time
The output power of wind generators depends on the wind
speed at that time.
The output power of wind turbine Pw is calculated as:
Pw = 0, Vs < Vi and Vs > Vo
Pw = Pwr*[(Vs-Vi) / (Vr-Vi)], Vs ≥ Vi and Vs ≤ Vr
Pw = Pwr, Vs ≥ Vr and Vs ≤ Vo
Where,
Vi = cut-in wind speed
Vr = rated wind speed
Vo = cut-out wind speed
Pwr = rated power output of wind turbine
Their values are taken as 5, 15, 45 m/s respectively.
9. DISCO Participation Matrix (DPM)
In an open market scenario a DISCO is free to purchase
power from any GENCO either in its own area or in other
area according to its convenience.
A contract between a GENCO and DISCO for purchase of
power is known as “bilateral transaction” and should be
approved by independent system operator. As there are
multiple GENCOs and DISCOs in every area several
combinations of GENCO-DISCO contracts are possible.
A DISCO participation matrix which is popularly known as
DPM is used for representing a set of GENCO-DISCO
contracts in the power system for the ease of visualization.
Number of rows and number of column in a DPM is same as
that of number of GENCOs and number of DISCOs in the
system.
10. Contract Participation Factor (CPF)
Each element of DPM matrix is known as contract
participation factor (CPF) that represents the fraction of total
load demand of a DISCO committed by a GENCO.
For example nth column element of mth row of a DPM i.e.
cpfmn denotes the fraction of total load demand of nth DISCO
supplied by mth GENCO. Hence, sum of each column of
DPM matrix should be unity.
DPM of a power system with P number of GENCO and Q
number of DISCO can be given as
11. EFFECT OF DPM
In deregulated environment, DPM is chosen on the basis of
open market strategy .
So it becomes important to see the effect of changing DPM
on the dynamic responses of the system involving wind
power plant. Also, controllers are to be optimized for
different DPMs, using ISE technique.
Table I shows the optimized values of integral controller gains
and electric governor parameters for the following two DPMs
13. The capability of smart grid power generation or ISO
operations w.r.t economical , cost and load flow
analysis are known as generation rate constraint.
This constraint includes:
Active power
Reactive power
Voltage
Frequency
Generation Rate Constraint
14. It is more realistic to add the physical constraints in the
power system, One such constraint is GRC.
Shows the comparison of dynamic responses with and
without GRC for deregulated wind integrated power
systems.
It is clearly seen that the responses become poorer in terms
of overshoots and undershoots and settling time. But it is the
more practical way to include GRC into the power system.
Effect of GRC
18. CONCLUSION
Frequency is one of the most important parameter to
determine the stability of a system.
To improve the overall dynamic performance in the
presence of the plant parameters changes and system
non linearities, the conventional integral controller
based AGC problem has been formulated.
Wind power plant is included in the system for taking
care of continously increasing load demands and in the
view of depleting conventional energy resources.
Transient responses hardly vary and becomes poorer
for varying DPM and GRC in terms of peak deviations
(overshoots and undershoots) and settling time.
