Energy storage power stations implement peak and valley electricity prices

Does energy storage affect peak-shaving cost?

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.

How do energy storage power stations work?

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.

Will energy storage become the second largest peak-shaving resource?

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.

Should energy storage power stations be built?

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.
