Role of grid integration of distributed generation in power quality enhancement: A review

This paper presents a comprehensive review on various impacts of DG integration on PQ and importance of proper grid-integration planning in light of maintaining PQ at the levels compliant with grid code requirements. It also focusses on the effective utilization of DGs for power quality enhancement in the utility grids. The proposed solutions essential for PQ enhancement in electricity networks with DG integration are also discussed. An overview of different issues associated with DG integration into utility networks has also been presented. Research areas pertaining to the improvement of PQ in grid-connected DGs are identified for further consideration with a focus on South Africa and the rest of African energy markets.
