Improvement of Power Quality by Simulation of Large Hybrid Wind Integrated Power Generation using STATCOM

Injection of the hybrid wind power into an electric power grid affects the power quality in power system. The influence of the wind turbine(WT) in the electrical power grid system concerning the power quality measurements are-the active power(P), reactive power(Q), variation of voltage sag & flicker, voltage dip, harmonics, distortion and electrical behavior of switching operation and greater flexibility to optimized for loss evolution criteria since convertor can be generated & absorb reactive power (Q). The power quality problem mainly due to installation of wind turbine (WT) with the electrical power grid. In this proposed scheme SVC (STATCOM) is coupled at a point of common connected with a battery energy storage system (BESS) to mitigation the power quality issues. The battery energy storage (BESS) is integrated to sustain the real power (P) source under changing hybrid wind power system. The STATCOM control scheme for the grid coupled hybrid wind energy generation system for power quality improvement is simulation using MATLAB SIMULATED in electrical power system block set. The effectiveness of the proposed scheme relives the main power supply source from the reactive power (Q) demand of the load and the Static var generator. The development of the power grid current transmission system incorporated power electronic based & other static controller to static to enhance controllability and increases power transfer capability.
