The battery energy storage system (BESS) is of such merits as high efficiency, long service life and adaptability to geographical conditions, besides its rated capacity and rated power can be configured independently. Taking the optimized total net proceeds of BESS in distribution network within its life cycle as the objective, the configuration of the battery in distribution network and the optimization of charging/ discharging values in different time intervals are researched while such factors as income of arbitrage, income from government’s feed-in tariff, reducing power wheeling cost, deferring facility upgrades and life cycle cost (LCC) are synthetically considered. A hybrid optimization model of configuring BESS is established, and a hybrid algorithm based on differential evolution (DE) and predictor-corrector interior point method (PCIPM) is put forward to solve this model. Finally, the configurations and net proceeds of sodium sulfur (NAS) battery, vanadium redox battery (VRB), polysulfide bromine battery (PSB), value-regulated lead-acid (VRLA) battery and lithium-ion (Li-ion) battery are compared through case studies, and the indices impact economic benefit are analyzed to validate the feasibility of the established model and the proposed algorithm, and some suggestions on the configuration plan of the battery are proposed.
