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...

Over the years, Nigerian power system is beset with lingering problems, which include severe losses, as well very low transfer capability of transmission network to evacuate from generating stations load at distribution level. Presently, industry undergoing restructuring, especially in generation and systems. In view deregulation electricity marketing, traditional practices are changes address ...

In these post COVID times, the world is going through a massive restructuring which India can use to its benefit by attracting foreign industrial investment. The major requirement reliable and ecofriendly electrical power source. Of late, renewable energy sources have increasingly become popular as alternative source of electricity. They provide immense aid in improving reliability system, when...

FACTS technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is oneof the most important FACTS devices used in the parallel compensation, enhancing transient stability andetc. Since three phase fault is widespread in power systems, in this paper STATCOM is used...

This paper presents a new Unified PowerQuality Conditioning System (MCUPQC),capable of simultaneous compensation for voltage and current in multi-bus/multi-feeder systems. By using one shunt Voltage-Source Converter(VSC) and two or more series VSCs the configuration is made. The system can be applied to adjacent feeders to compensate for supplyvoltage and load current imperfections on the main ...

Abstract In this paper, the impact of communication time delays (CTDs) on combined load frequency control (LFC) and automatic voltage regulation (AVR) a multi-area system with hybrid generation units is addressed. Investigation reveals that CTDs have significant effect performance. A classical PID controller employed as secondary regulator its parametric gains are optimized differential evoluti...

in this paper, we present a new method to determine the optimal location and parameter settings of unifiedpower flow controller (upfc) for removing voltage violations and transmission lines overloading. upfc isconsidered as the most powerful member of the facts devices, that it can control shunt and series power flow.this option gives to upfc the power to control the voltage profile and transmi...

In this study, a fuzzy proportional integral derivative controller (FPID) was adjusted using the differential evolution (DE) method to enhance automated generation control (AGC) of three-zone reheat-type power system. The objective function used in study an time-weighted absolute error (ITAE). optimization, gain parameters (PI), (I), and FPID were optimized compared improve limitations drawn by...
