摘要
Based on calendar and cycle degradation characteristics of batteries, a power dispatch optimization model of a multi-type battery energy storage system was proposed. Effects of power dispatch of the multi-type battery energy storage system on capacity degradation of each battery and total cost of the hybrid power system were investigated. The application and effectiveness of the proposed model were verified and illustrated through a photovoltaic-wind-biomass-batteries hybrid power system. The results show that the minimum total cost and the corresponding power dispatch schemes of the hybrid power system can be obtained by the proposed method. In addition, the hybrid power system chooses the cheapest battery to reduce the total cost of the hybrid power system when taking the cycle degradation into consideration, while it chooses batteries with relatively low costs of calendar and cycle degradation when taking both calendar and cycle degradation into consideration. © 2019, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
