Flexible alternating current transmission system (FACTS) controllers are important to enhance the quality of power in systems. The stability a is achieved via FACTS device (a Static Synchronous Compensator (STATCOM)). This paper aims control losses during peak energy demand circumstances with minimal economical and functional efficiency system. STATCOM operation seven level voltage source conve...

This paper deals with PID compensator control of Synchronous Rectifier (SR) Buck Converter to improve its conversion efficiency under different load conditions with the help of a Zero Voltage Switching(ZVS)Logic Circuit. Since the freewheeling diode is replaced by a high frequency switch MOSFET in this buck configuration, the SR control technique itself will be sufficient under heavy load condi...

The most difficult aspect of optimizing a wind farm is creating an accurate model, especially if the connected to grid. inconsistency and unpredictability speeds exacerbates this issue. When dealing with farms, it possible that reactive power addition capabilities individual turbines are insufficient meet network requirements. This due cable losses line between PCC. study employs doubly fed ind...

This paper presents the impact of the Static Synchronous Compensator (STATCOM) on the performance of distance protection of EHV transmission lines. A 400kV transmission system having midpoint connected STATCOM with its control circuit is modeled using MATLAB/SIMULINK software. The impact of STATCOM on distance relay for different fault conditions and different fault locations is analyzed. Simul...

This paper presents an Interior Pont Method (IPM) and Evolutionary Particle Swarm Optimization (EPSO) based hybrid method to solve optimal power flow in power system incorporating Flexible AC Transmission Systems (FACTS) such as Static Synchronous Series Compensator(SSSC) for security enhancement in the power systems. A fuzzy logic composite criteria based severity index is also used as an obje...

Damping of inter-area electromechanical oscillations is one of the major challenges to the electric power system operators. This paper presents Gravitational Search Algorithm (GSA) for tuning Static Synchronous Series Compensator (SSSC) based damping controller to improve power system oscillation stability. In the proposed algorithm, the searcher agents are a collection of masses which interact...
