ABSTRACT
This paper presents a new methodology to reduce harmonic distortion in UPQC using artificial neural network
and fuzzy logic controller. So this paper main aim is improve power quality by using UPQC with ANN and FLC. The most purpose of the proposed (ANN & FLC) is capable of providing good static and dynamic performances compared to PI controller. The UPQC is to control on voltage flicker/unbalance, reactive power and harmonics. In different words, the UPQC has the potential of up power quality at the purpose of installation on power industrial power systems. The appliance of computing is growing quick within the space of power electronics and drives. From olden days to now days we are using twelve switches used in back to back configuration. But now we are using nine switches instead of 12
switches. In 9 switch UPQC converter given the most useful benefits compared to 12 switches power converter. The nine switches UPQC converter gets the best results by using of three methods. They are one is PI controller technique, ANN controller technique and FLC controller technique. By contrast PI, FLC and ANN, ANN is better than (FLC & PI) for power quality enhancement and voltage sag and voltage swell mitigations. The factitious neural network (ANN) is taken into account as a replacement tool to style management electronic equipment for power quality (PQ) devices. A whole
simulation study is administrated to analysis the performance of the ANN controller and compares its performance with the quality FLC & PI controller’s results. The nine-switch convertor has already been proved to possess sure benefits,
additionally to its part saving topological feature. Despite these benefits, the nine-switch convertor has thus far found restricted applications because of its several perceived performance tradeoffs like requiring associate degree outsized
dc-link capacitance, restricted amplitude sharing, and unnatural part shift between its 2 sets of output terminals. Rather than acceptive these tradeoffs as limitations, a nine-switch power conditioner is projected here that nearly “converts” most of those topological short comings into fascinating performance benefits. Aiming more to cut back its switch losses,
Harmonics, Voltage Sag & Swell associate degree acceptable discontinuous modulation theme is projected and studied here thoroughly to doubly make sure that top reduction of commutations is achieved. With associate degree suitably
designed management theme with PI and ANN with Fuzzy logic controller then incorporated, the nine-switch convertor is shown to favorably raise the general power quality in Simulation, thus justifying its role as an influence conditioner at a reduced value.

This paper presents a comprehensive survey of DSTATCOM control strategies put forward recently. It is
aimed at providing a broad perspective on the status of DSTATCOM control methods to researchers and
application engineers dealing with harmonic suppression issues. Many control techniques have been
designed, developed, and realized for active filters in recent years. The proposed DSTATCOM consists of a
three-leg Voltage Source Converter (VSC) with a dc bus capacitor. The PV array or battery operated boost
converter is proposed to maintain the dc link voltage of the dc bus capacitor for continuous compensation
for the load. This paper presents to evaluate the performance comparison of two control strategies for
extracting the reference currents to control the proposed DSTATCOM. The two control methods are
Synchronous Reference Frame (SRF) theory and IcosΦ algorithm. The performance of the DSTATCOM is
validated using MATLAB software with its simulink and Power System Block set (PSB) toolboxes. The
simulation results for the two control methods are compared to validate the superior performance of the

TRANSMISSION LOSS MINIMIZATION USING ADVANCED UNIFIED POWER FLOW CONTROLLER (...ijiert bestjournal
The capability of transmission loss minimization of the power system network by
advanced unified power flow controller (UPFC) is the main focus in this paper. An
important factor effecting power transmission systems today is power flow control. The
increment of load variation in a power transmission system can lead to potential failure on
the entire system as the system has to work under a stressed condition. Thus, the Flexible
AC Transmission System (FACTS) are integrated in power system to control the active
power and reactive power simultaneously in specific lines and improve the security of
transmission line without violating economic generation dispatch. This paper presents
Advanced Unified Power Flow Controller (UPFC) which can provide functional flexibility
for loss minimization and voltage profile monitoring in a power system network. The
UPFC devices are installed in the system based on voltage stability index in order to
enhance the system security, performed on the IEEE 30-bus RTS for several loading
conditions. Simulations were carried out using MATLAB software to check the
performance of UPFC.

Integration of Unified Power Quality Controller with DGIJRST Journal
This paper gives an insight into the analytical results of the intergration of Unified power quality controller (conditioner) with distribution generation system. The intergration is achieved by connecting the DClink throught rectifier to the distribution generatoion along with thwe connection of the series and shunt inverter to the same dc link. This type of connection can account for the voltage sag, voltage swell, along with the reduction of harmonics and also compensation of reactive power. The analysis is supported with the simulation which will are discussed in detail in the paper.
Improvement of power quality has to be treated as a matter of at most importance in the open
market economy due to the increased use of non linear loads. Several devices have been used to mitigate
the power quality problems. Now a days researchers are concentrating on the use of FACT devices to
overcome power quality issues. Unified Power Quality Conditioner is one among such FACT devices upon
which this paper has concentrated for mitigating the Power Quality problems. Here a 3 phase 3 wire
UPQC is realised using MATLAB/SIMULINK to mitigate voltage sag and swell as well as to maintain
sinusoidal voltage and current at PCC irrespective of load dynamics.

Mitigation of Voltage Imbalance in A Two Feeder Distribution System Using IupqcIJMERJOURNAL
ABSTRACT: Proliferation of electronic equipment in commercial and industrial processes has resulted in increasingly sensitive electrical loads to be fed from power distribution system which introduce contamination to voltage and current waveforms at the point of common coupling of industrial loads. The unified power quality conditioner (UPQC) is connected between two different feeders (lines), hence this method of connection of the UPQC is called as Interline UPQC (IUPQC).This paper proposes a new connection for a UPQC to improve the power quality of two feeders in a distribution system. Interline Unified Power Quality Conditioner (IUPQC), specifically aims at the integration of series VSC and Shunt VSC to provide high quality power supply by means of voltage sag/swell compensation, harmonic elimination in a power distribution network, so that improved power quality can be made available at the point of common coupling. The structure, control and capability of the IUPQC are discussed in this paper. The efficiency of the proposed configuration has been verified through simulation using MATLAB/ SIMULINK.
Harmonic analysis and Power factor improvement with UPQC under two Novel cont...IJERA Editor
This paper presents unified power quality conditioner (UPQC)for power quality improvements in terms of
harmonics compensation and power factor correction in a three-phase four-wire distribution system.The UPQC
is implemented with PWM controlled voltage source converter (VSC) and switching patterns are generated
through Indirect PI and Synchronous Reference Frame controller. The selected topology for voltage source
converter is the three-leg and six-leg VSC for Indirect PI and Synchronous reference frame (SRF) control
strategies respectively. The behavior of UPQC has been analyzed by considering a case study with switching of
three phase half bridge diode rectifier and a parallel star connected unbalanced R-L loads. Harmonic spectrum
of the source current and load voltage are compared in between without UPQC and with UPQC by considering
both control strategies. The complete system has been modeled using MATLAB software with its stimulus’s
sim power system toolboxes.

This paper introduces a new optimization method to determine the optimal allocation of Unified Power Quality Conditioner (UPQC) in the distribution systems. UPQC is a versatile Custom Power Device (CPD) to solve problems related to voltage and current by the series and shunt compensator in the distribution systems. The task of UPQC highlighted in this paper is the required load reactive power is provided by both the series and shunt compensators. The UPQC’s steady state compensation capability has given a solution for providing reactive power compensation in large distribution systems. The optimization method adopted is Moth Flame Optimization (MFO). The best location and series compensator voltage are determined using MFO. The voltage injected by the series compensator and reactive power injected by the shunt compensator is incorporated in the load flow method. The effectiveness of the proposed method is validated with standard distribution systems.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
