Area energy storageIt refers to the storage and release of electric energy through the installation of energy storage equipment (such as batteries, super capacitors, etc.) in the distribution network, so as to balance the load of the power grid and improve the reliability of power supply. This kind of energy storage equipment is usually installed in the power distribution station or station area where the distribution transformer is located, which is used to deal with the instantaneous load fluctuation and peak load demand in the distribution network, improve the stability and response speed of the power grid, and play an important role in peak filling, peak supply, safety and stability, frequency regulation and so on.
With the comprehensive and high-quality development of the economy and society, the demand for electricity in the rural power grid is increasing year by year, and some mountain villages are scattered and far away from the main power supply network, and there are heavy overload and low voltage problems caused by the large power supply radius, which is difficult to meet the customer's requirements for power quality. At the same time, the problem of overvoltage and photovoltaic consumption caused by the rapid development of photovoltaic is difficult to achieve dynamic governance in a short time.
When the station is faced with heavy overload and voltage limit, the energy storage system can respond quickly to provide the necessary power support, and at the same time can effectively balance the grid voltage and prevent the occurrence of voltage limit problems. Through real-time monitoring and analysis of the three-phase voltage and current of the distribution network, the energy storage system accurately adjusts the current distribution of each phase and balances the voltage amplitude of each phase, thereby improving the power supply quality and operating efficiency of the distribution network.
Through the sharing of energy storage microgrid by the station group, the surplus electricity generated by photovoltaic power generation during the day between villages will be automatically stored in the energy storage system or consumed across the station area. When the electricity load of villagers increases at night, the energy storage system automatically releases electric energy to assist in adjusting the balance of supply and demand, thus playing the role of peak cutting and valley filling.
