This paper established the load peak–valley partition model and demand response model corresponding to every period based on load peak–valley characteristics.
On the other hand, references [35, 36] do not consider the impact of energy storage utilizing peak and off-peak electricity price arbitrage on the peak-shaving cost of the power system, thus failing to fully utilize the peak-shaving capabilities of energy storage.
By 2030, the scale of energy storage will expand rapidly, becoming the second largest peak-shaving resource in addition to thermal power units, as shown in Table 1. With the abundance of peak-shaving resources and the development of power auxiliary service market, the optimization of peak-shaving cost of power system has become an urgent problem.
All thermal power units have no change in the start-stop state in 24 periods, so there is no start-stop peak-shaving cost. The consumption of renewable energy in typical winter days is shown in Fig. 13. It can be seen that there are different degrees of renewable energy abandonment during periods 12–17.
According to the typical daily renewable energy and load characteristics of Ningxia region, the quantification model of power system peak-shaving cost is established. The model takes into account the time-of-use electricity price factor. The objective function is to minimize the total peak-shaving cost of power system.
The quantization model of peak-shaving cost is a mixed integer optimization problem. This is because it contains some 0–1 variables, such as yi,t. The Yalmip toolbox in Matlab can be used to solve linear programming, integer programming, nonlinear programming, mixed programming and other standard programming problems.
