Mitigation of Voltage dip in WECS using UPQC [PDF]
International Journal of Trend in Scientific Research and Development, 2018 Currently, the quality of supplied power is important to several customers. Power quality is a service and many customers are ready to pay for it. In the future, distribution system operators could decide, or could be obliged by authorities, to supply their customers with different PQ levels and at different prices.
