The load of the power system is always fluctuating, for example peak loads may occur in the morning and evening, and a valley of loads may occur from 10 pm to 6 pm later. In order to level up the peak of the power system and fill up the valley, the planned power utilization and the energy saving of the user are promoted, the economic leverage of the price is fully exerted, and the peak-valley power pricing can be realized.

For users who use electricity during peak load period, the electricity price is higher than that of normal electricity consumption regardless of the basic electricity price or the electricity consumption price. The peak-valley electricity price is realized by a time-sharing metering method, otherwise, the evaluation is unavailable.
