In this section, energy storage power stations are considered and the optimal grid-connected strategy based on load fluctuation is adopted. The maximum charge and discharge power of energy storage power stations is 150 MW. The operating results of the energy storage power station are shown in Fig. 7.
Such a grid-connected strategy not only makes the load fluctuation after grid-connected as stable as possible but also optimizes the operation income of new energy sites. Due to the completion of “Peak shaving and valley filling”, also reduces the output of high-pollution and high-cost units to a certain extent.
