Capacity configuration optimization model of industrial load and energy storage system Considering the tough environment, two ESSs are compared to analysis their annual economic profitability. In addition, the proposed optimization accounts for the discount rate of fund flow. 3.1. Objective function
In , two models are proposed, one is the energy storage evaluation model in the planning stage, and the other is the two-stage large user energy storage optimization model of demand management binding peak valley arbitrage in the operation stage.
The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation.
The actual operating conditions and battery life should be considered in the optimal configuration of energy storage, so that the configuration scheme obtained is more realistic.
The upper-layer model solves the energy storage station capacity configuration problem, while the lower-layer model solves the optimization operation problem of the multi-microgrid system.
Therefore, the energy storage system is configuration mainly based on the time domain and frequency domain to optimize the configuration of the energy storage system capacity and the study of energy storage control strategies.
