The largest distributed energy storage project in China has been put into operation
2024-04-17
Recently, the largest distributed energy storage project in China designed by China Energy Construction Shaanxi Institute, the first user-side distributed energy storage project in China, the distributed energy storage project in Shaanxi Province's large-scale distribution station area, was completed and put into operation! The project has deployed and installed 149 sets of distributed energy storage equipment in the station area, covering an area of nearly 8000 square kilometers in Guanzhong, southern Shaanxi and other counties and cities in Shaanxi. Since the start of the project, China Energy Construction Shaanxi Institute has surveyed 422 distribution station areas. Through solid investigation of the historical data of the station area and detailed analysis of the operation characteristics of the station area, it has put forward a targeted energy storage solution. It has made full use of the rapid response and flexible adjustment of the energy storage system to effectively solve the problems of the problems of the problems of the problems of voltage limit and distributed the flexible adjustment capacity of the station area and the flexibility of the operation of the distribution network extend the reading station area energy storage refers to the distribution network, by installing energy storage equipment (such as batteries, super capacitors, etc.) to achieve the storage and release of electrical energy to balance the grid load and improve the reliability of power supply technology. 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.
