Owing to the rapid growth of Renewable Energy Sources, Microgrid finds greater significance in satisfying consumer need in today’s world. However, the increased number of Distributed Energy Resources might introduce power quality issues in a grid connected microgrid system due to the intermittent nature of such natural resources and power electronic converters associated with their conversion. So as to compensate such power quality issues, this paper proposes a Custom Power Device (CPD) namely Photovoltaic -Dynamic Voltage Restorer (PV-DVR), which uses a PV as a source for the Battery Energy Storage System (BESS). A PMSG driven PV Microgrid system with a MPPT controller for maximum power extraction from PV source and a hysteresis controller for effective grid synchronization and lesser harmonic distortion is taken for analysis. The dynamic performance of the grid connected microgrid system with DVR is analyzed for various loads and different power quality issues like voltage sag/swell, harmonics, interruption etc. Wavelet Transform based switching controller is used to detect the power quality event occurring and operate the PV-DVR accordingly.

使用 PV-DVR 改善电能质量的混合光伏-风电系统

由于可再生能源的快速增长,微电网在满足当今世界消费者需求方面具有更大的意义。然而,由于此类自然资源和与其转换相关的电力电子转换器的间歇性,分布式能源数量的增加可能会在并网微电网系统中引入电能质量问题。为了弥补此类电能质量问题,本文提出了一种定制电源设备(CPD),即光伏-动态电压恢复器(PV-DVR),它使用光伏作为电池储能系统(BESS)的来源。PMSG 驱动的光伏微电网系统具有用于从光伏源中提取最大功率的 MPPT 控制器和用于有效电网同步和较小谐波失真的磁滞控制器进行分析。
