This paper studies and proposes the Volt-Var control curve considering DER(Distributed Energy Resources) transformer voltage tap.
As DER is increasing around the world, DER is required to have a system support function for power system stability. Recently, even in Korea, the power system support function is required for the DER. In particular, the Volt-Var reactive power function will be used to solve the overvoltage problem caused by the increase in generation of DER in distribution system. DER in the domestic distribution system uses a transformer to connect into the distribution system, and the transformer voltage tap is set differently depending on the system situation. Therefore, this paper analyzes the suitability of the Volt-Var control curve in the domestic system by considering the transformer voltage tap, and suggests a method for setting the Volt-Var control curve suitable for the domestic system |
