Customer ServiceIn the power system, the load usually shows “peak” and “valley” differences. It refers to the fact that the load is higher during certain times of the day and lower during other times of the day. In order to meet the peak demand, the power system needs to carry out peak-shaving.
The problem of peak-shaving in the Ningxia power system Peak-shaving refers to the reasonable adjustment of power system according to the change of power load to ensure the reliability and stability of a power supply. In the power system, the load usually shows “peak” and “valley” differences.
A method to determine the scheduling of the pumped storage hydropower plants to have the maximum impact on peak-shaving and valley filling, considering the daily generation scheduling program of the thermal units in Iran power grid was proposed in .
Driven by the peak and valley arbitrage profit, the energy storage power stations discharge during the peak load period and charge during the low load period. They play the role of “cutting peak and filling valley” and realize the full utilization of energy storage resources.
The energy storage power stations are in the discharge state during periods 7 to 8 and 20 to 23. In the rest of the period, the load power demand is met by renewable energy units, thermal power units and fixed output units. The deep peak-shaving grade of 300 MW, 600 MW and 1000 MW units on typical summer day are shown in Fig. 9.
On the one hand, by building new energy storage power stations, the adjustable capacity of energy storage resources is increased. On the other hand, the time-of-use tariff mechanism is used to reasonably arrange charge and discharge to achieve cost recovery of energy storage investment.
