The invention discloses a peak shaving and valley filling real-time control method for a waste battery system, and relates to the technical field of waste battery utilization. The method is characterized by comprising the steps of 1, acquiring time data through an energy storage system in real time so as to judge power consumption; if current time is staged power time, starting a main network to supply power to the energy storage system; and if the current time is not the staged power time and a judgment result is no, entering an end state, wherein the frequency of acquiring the time data obtained by the energy storage system is that sampling is performed once at an interval of 1 hour. According to the peak shaving and valley filling real-time control method for the waste battery system, the power consumption is judged by acquiring the time data through the energy storage system in real time, and the charging power of a battery pack is reduced or improved for batteries with different capacity performances by comparing the data, so that the accidents during energy storage of the battery pack are avoided; and an optimized result can effectively reduce the accidents of the waste battery energy storage system.
Description
technical field [0001] The invention relates to the technical field of waste battery utilization, in particular to a real-time control method for peak shifting and valley filling of a waste battery system. Background technique [0002] The battery energy storage system can realize the peak-shaving and valley-filling function of the load by discharging at the peak of the load and charging at the valley of the load. For the power grid, using the battery energy storage system to shave peaks and fill valleys can delay equipment capacity upgrades, improve equipment utilization, and save equipment update costs; for users, using battery energy storage systems to shave peaks and valleys can take advantage of peak and valley electricity prices Poor economic benefits. There are already many large-scale BESSs in operation abroad; in China, China Southern Power Grid has launched demonstration projects for megawatt-scale battery energy storage systems. [0003] A waste battery is a bat...
