大規模連系系統における太陽光発電の出力抑制を考慮した最適潮流計算による経済負荷配分制御

Although various studies investigated on photovoltaic (PV) energy curtailment in a bulk power system in recent years, they rarely considered transmission network constraints or cross-regional power exchange. In this study, we develop an economic-load dispatching (EDC) control method by optimal power flow (OPF) with PV energy curtailment considering transmission network constraints. Firstly, we propose a PV energy curtailment method considering transmission network constraints. Secondly, we propose an EDC method considering cross-regional power exchange in the interconnected power systems. The effectiveness of the proposed methods is evaluated by simulations conducted on IEEJ EAST 30-machine system model representing interconnected bulk power systems.
