Multi-objective optimal allocation model of hybrid energy storage capacity based on generation, transmission and consumption demand

Abstract

Current research on the optimal allocation of hybrid energy storage system (HESS) capacity lacks consideration of both consumption and user demand. Most of the available literature only considers unilateral demand. Therefore, this paper proposes a hybrid energy capacity allocation method that considers both wind power and user two-way demand. First, a flexible load model is constructed from the user-side demand response characteristics. Second, a HESS composed of batteries and super capacitors is established, and a HESS charging and discharging strategy is proposed. Again, the capacity optimization model is constructed with the objective function of the lowest cost, the smallest wind abandonment rate, and the highest electricity satisfaction of the HESS. Finally, in order to verify the effectiveness of the model, an arithmetic example analysis is carried out.
