Power quality issues are becoming a major concern of today's power system engineers. Shunt active power filter (SAPF) is one of the effective means for harmonic current compensation in electrical power system. The performance and dynamic characteristics of a three-phase SAPF with a simple control algorithm is presented and analyzed in this paper. This algorithm operates at fixed switching frequ...

With the incremental introduction of solar photovoltaic (PV) generators into existing power systems, and their fast-growing share in the gross electricity generation, system voltage stability has become a critical issue. One of the major concerns is voltage fluctuation, due to large and random penetration of solar PV generators. To suppress severe system voltage deviation, reactive power contro...

This paper introduces a versatile control scheme for unidirectional ac–dc boost converters using fuzzy logic controller for the purpose of mitigating grid power quality. Since most power factor correction circuits available in the commercial market utilize unidirectional ac– dc boost converter topologies, this is an almost nocost solution for compensating harmonic current and reactive power in ...

This paper presents dynamic modeling and simulation of Brushless Doubly Fed Induction Generator (BDFIG) as an alternative for variable speed wind power applications. The mathematic models of active and reactive power for BDFIG have been developed. The power control systems of a 75 kVA generator and wind turbine were simulated in Matlab/Simulink/SymPower Systems. The generator’s control system i...

The static synchronous compensator (STATCOM) is one type of FACTS devices which resembles in many respects a rotating synchronous condenser used for voltage control and reactive power compensation. The STATCOM can increase transmission capacity, damping low frequency oscillation, and improving voltage stability. This paper presents a control block diagram of STATCOM for the voltage stability im...
