Voltage Management Method of Distribution System in P2P Energy Transaction Environment

Abstract

Abstract Energy consumers are evolving into energy prosumers that simultaneously perform the role of production and consumption. The activation of energy transaction owing to the increase of energy prosumers affects the stability management of distribution system. Accordingly, the role of the distribution system operator (DSO) for managing the power distribution system is becoming important. In a power distribution system with low demand, if a prosumers trade large amounts of power through peer-to-peer energy transaction (P2P-ET), an overvoltage problem may occur. In this study, a distribution system voltage management method through interaction between DSO and local energy transaction community (LETC) which performs P2P-ET is proposed. The effect of the proposed model is validated through a case study considering the LETC that local prosumers pool-based P2P-ET is performed.
