Problems solved by technology
[0005] However, there is not enough research on the access control of battery energy storage power stations. At present, for the access and control process of battery energy storage power stations, empirical methods are often used, that is, combined control of battery energy storage power stations based on the experience of grid personnel Process control and adjustment, not only strong subjective factors, but also low efficiency, and low scientific and reliability

The invention discloses a battery energy storage power station access control method, which includes acquiring grid operation data; determining the access point of the battery energy storage power station; formulating a charging and discharging scheme for the battery energy storage power station; completing the control of the battery energy storage power station, realizing The peak-shaving and valley-filling function of the battery energy storage power station. The invention realizes the application of peak-shaving and valley-filling to different trunk lines, so as to improve the power quality and the stability of the power grid. At the same time, the utilization rate of the battery energy storage system is improved through multiplexing, and according to the load characteristics of the connection line of the battery energy storage system, a corresponding peak-staggered charging and discharging plan is formulated to realize the improvement of battery energy storage when the power grid is completed. The utilization rate of the system can alleviate the contradiction between the low utilization rate of power equipment caused by the large difference between the load peak and the trough and the stability problem of the power grid caused by insufficient reserve capacity. Therefore, the method of the invention has high reliability, good economy, wide applicability, and convenience.
Description
Technical field [0001] The present invention relates generally to a battery storage power station access control method. Background technique [0002] With the development of economic technology and the improvement of people's living standards, electricity has become a secondary energy in people's production and life, bringing endless convenience to people's production and life. Therefore, the reliable and stable operation of the power system becomes one of the primary tasks of the power system. [0003] The problem of grid peak valley balance is always the key to the construction and operation of the grid. On the power generation side, with fluctuations such as wind power, photovoltaic, uncertain new energy is rapidly developed, and the large-scale power generation grid is challenged for power grid peak capabilities. It is necessary to need enough capacity controllable load, participate in the daily grid valley balance process. . On the electricity side, the power load is mainly...
