WECS Based Microgrid Supported by PV Generation for Interline Active Power Quality Conditioning

摘要

The microgrid (MG) 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 challenges arise in 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. In addition, the compensation will be more effective if a number of lines are being offered compensation at the same time instead of one at one time. Hence the enhanced device for interline PQ conditioning is considered. 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.
