储能系统与需求响应资源相结合，提高了减少需求的性能可靠性，并提供了额外的好处。然而，当两者同时运行时，需求响应资源和储能系统并不一定基于应用周期来保证额外的效益，即，如果储能系统仅用于提高需求响应资源的性能可靠性，则效益降低。因此，为了通过具有多种用途(需求响应、售电、调峰等)的储能系统实现效益最大化，我们必须为每个目的分配适当的输出(充放电能量)。本文提出了一种计算最优需求响应登记容量的方法，通过储能系统的混合运行来最大化总体利润。此外，多用途储能系统的利润和最优需求响应登记容量取决于储能系统和电力调节系统容量，因此，本研究估算了最优需求响应登记容量和一个储能系统和电力调节系统容量的最优组合。因此，当平均C-Rate为0.81C并且最佳登记容量为其最大值的81%时，出现最大利润。
Energy storage systems combined with demand response resources enhance the performance reliability of demand reduction and provide additional benefits. However, the demand response resources and energy storage systems do not necessarily guarantee additional benefits based on the applied period when both are operated simultaneously, i.e., if the energy storage system is used only to increase the performance reliability of demand response resources, the benefit decreases. Thus, to maximize the benefits via an energy storage system with multiple purposes (demand response, electricity sales, peak shaving, etc.), we must allocate the proper output (charging and discharging energy) for each purpose. This paper proposes a method for calculating the optimal demand response registration capacity, which maximizes the overall profit via the energy storage system hybrid operation. In addition, the profits and optimal demand response registration capacity of energy storage systems with multiple purposes depend on the energy storage system and power conditioning system capacity; therefore, this study estimates the optimal demand response registration capacity and optimal combination with an energy storage system and power conditioning system capacity. Consequently, the maximum profit occurred when the average C-rate was 0.81C and when the optimal registration capacity was 81% of its maximum.
