This paper presents a three-phase three-wire solar photovoltaic (PV) based DSTATCOM that can improve power quality problems. The solar PV system is designed based on peak-sun approach and simulated in HOMER (Hybrid Optimization Model for Electric Renewable) software. The technical and economic feasibility of different combinations of the system sizing are evaluated based on cost of electricity (COE), the net present cost (NPC) and the percentage of excessive electricity produced. The optimum size of PV system the will be able to supply the load with improved power quality features without any additional hardware to the system. The cost of electricity (COE) of the proposed system is still lower than the feed-in tariff (FiT) scheme provided by the government. Thus, the results showed that the proposed system is viable to improve the power quality at the distribution network.
