Research on the Application of Peak-Valley Time-Sharing Tariffs in Customer-Side Energy Storage Systems

High wind abandonment rate, insufficient consumption, is the main problem that restricts the development of China’s wind power industry. Restricted by the power structure, grid network and power load characteristics, some of China’s regional power grid peak capacity is limited, unable to meet the demand to further improve the level of wind power consumption; and wind energy resources are more centralized, away from the load center, the grid scheduling capacity is limited. Therefore, demand-side response has become an important breakthrough to solve the problem of wind abandonment, peak and valley time-sharing tariff is an important means of demand-side response, this mechanism to price as an economic lever, can guide the user to reasonably adjust the demand for electricity, to realize the peaks and valleys to fill in the valley, increase the valley of the wind power online power, thus improving the wind power consumption capacity. Explore the development of wind power peak and valley time-sharing tariffs and their effective implementation, for solving the current wind power abandonment problem is very necessary, has a high practical research value. In this paper, on the basis of in-depth analysis of the peak and valley tariff and its role in the mechanism, the establishment of the peak and valley time-sharing tariff pricing mechanism based on the consumption of wind power, and its application in the user-side energy storage system, to solve the current problem of large-scale wind power abandonment, to improve the efficiency of renewable energy utilization, resource conservation, and to improve the quality of the environment, has a very important significance.
