This period is divided into valley periods, and the rest of the period is divided into regular periods. According to the net load, the peak-to-valley electricity price periods are further optimized, and the optimized electricity prices for valley, flat, and peak periods are 0.28 RMB/kW·h, 0.42 RMB/kW·h, and 0.91 RMB/kW·h, respectively.
