Abstract——Injection of the wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation and these are measured according to national/international guidelines. The paper study demonstrates the power quality problem due to installation of wind turbine with the grid. In this proposed scheme
STATic COMpensator (STATCOM) is connected at a point of common coupling with a battery energy storage system (BESS) to mitigate the power quality issues. The battery energy storage is integrated to sustain the real power source under fluctuating wind
power. The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system block set. The effectiveness of the proposed scheme relives the main supply source from the reactive power demand of the load and the induction generator. The development of the grid co-ordination rule and the scheme for improvement in power quality norms as per IEC-standard on the grid has been presented.

该模型的目的是将背靠背 HVDC 模块化多电平转换器 (MMC) 模拟为为整个电网供电的电能质量调节系统。 因此，模块化多电平逆变器作为远端转换器运行，或也称为孤岛模式。 这种电能质量调节系统的主要目标是能够保护敏感的电网免受瞬态电压骤降的影响。 这是通过利用 MMC 子模块的内部能量存储以及在瞬态电压骤降期间将线路电流控制为标称值的整流器来实现的。 这形成了一个非常灵活和即时的缓解系统。 除此之外，该系统还具有无功补偿、低谐波失真和出色的冗余等多项强大功能。
