| Research Abstract |
The widespread installation of distributed generation systems is crucial in making the maximum use of renewable energy. However, local distribution networks face voltage fluctuation problems if excess photovoltaic (PV) systems are connected to them. This study proposes a scheme that solves the problem of voltage fluctuations in a distribution network with high penetration of PV systems by using customer-side energy storage systems. Through the numerical simulation based on actually monitored minute-by-minute solar irradiation data, this study evaluates the economic advantage of the proposed scheme.
