Active Power Quality Enhancement of Wind Microgrid Supported by PV Generation

摘要

The power generation in the microgrid is mainly based on renewable energy sources. They are becoming increasingly attractive to consumers as a great number of them are installed at consumer’s sites. In the present work two renewable energy sources, PV and Wind are considered. The microgrid is constituted by a wind generating system and supplies quality power to the local load. Many power quality issued have been raised as renewable energy-based power generation is not a constant source of the supply as the power generated directly relies on the environmental conditions. The challenge is maintaining the output voltage at constant. In addition, linear and nonlinear loads connected to the MG also affect the power quality in the MG. However, the concerned issues can be mitigated well by taking the aid from another renewable source namely PV. The power quality issues occurring during load and generation balance in MG are examined and the mitigation by using PV support is presented in this paper.
