Abstract

This paper proposes a voltage-control strategy for the distribution system with high photovoltaic (PV) penetration to reduce the voltage rise and comply with the voltage regulation limits. The control strategy can lower feed-in active-power curtailment of the PV systems simultaneously to solve the over-voltage problem. The proposed voltage-control strategy is realized by managing the transformer on-load tap changer (OLTC), the energy storage system (ESS), and real and reactive power control of the PV inverters. Furthermore, to optimize capacities of the ESS and the PV inverters, a two-level optimization procedure based on particle swam optimization (PSO) and dynamic programming (DP) is proposed. To verify the feasibility of the proposed strategy, real data of PV power generation and load profile are used to analyze the effectiveness of the proposed method. In addition, comparisons are made for the proposed method and the reference method. The simulated numerical results reveal that the proposed strategy can provide more effective voltage-control and increase economic benefits, as compared with the reference method.
