A fuzzy logic- (FL-) based control technique for unified power flow controller (UPFC) to resolve the quality issues in transmission network is presented this paper. MATLAB/Simulink used design FL-based controllers shunt and series converters of UPFC, which validated on 4-bus system. In addition, performance suggested UPFC compared with PI (proportional integral), HC (hysteresis controller), MPC...

This paper proposes a hybrid technique for secured optimal power flow coupled with enhancing voltage stability with FACTS device installation. The hybrid approach of Improved Gravitational Search algorithm (IGSA) and Firefly algorithm (FA) performance is analyzed by optimally placing TCSC controller. The algorithm is implemented in MATLAB working platform and the power flow security and voltage...

This paper proposes a small wind energy conversion system comprises permanent magnet synchronous generator (PMSG), uncontrolled rectifier, conventional H-Bridge inverter and dc-dc bi-directional converter. The dc link capacitor is connected to a storage system through Bi-directional power flow link. A hybrid pulse width modulation (HPWM) controller is used to regulate the ac load voltage and fr...

The demand of electricity globally led to the concept renewable energy resources for power generation that are eco-friendly and freely available from nature. solar photovoltaic systems wind-based generators considered as primary called Distributed Generation units they scattered in These operated with bidirectional converters by providing auxiliary services at grid side load either mode microgr...

This article presents a novel control scheme for achieving optimal power balancing and congestion control in electrical energy transmission networks via nodal prices. We develop an explicit controller that guarantees economically optimal steady-state operation while respecting all line flow constraints in steady-state. Due to these constraints, the resulting optimal control law has a piecewise ...

This paper presents modeling and control of a hybrid distributed energy sources including photovoltaic (PV), fuel cell (FC) and battery energy storage (BES) in a microgrid which provides both real and reactive power to support a utility grid using fuzzy sliding-mode control (FSMC). The overall configuration of the microgrid including dynamic models for the PV, FC, BES and its power electronic i...

Distributed flexible AC- transmission system (D-FACTS) is a recently advanced FACTS device with high flexibility and smaller size. The DPFC can control power flow in transmission lines, regulate bus voltages and it can also enhance stability margin in power grids. Adaptive-neural network-based fuzzy inference system (ANFIS) combines features of artificial neural network and fuzzy controller. Th...
