- Abstract:
- The operation of water supply and drainage plants and stations need to consume great amount of electric energy, and the electricity consumption has a certain variation cycle, there are many problems that affect the reliability of electricity consumption. The energy storage power station uses the principle of battery energy storage to charge and discharge power from the grid through the energy storage and release system during the peak and valley periods of the city, achieving the effect of balance and can use the peak and valley tariff rate difference to reduce part of the electricity cost. It can also be used as a shortterm emergency power supply for plants and stations when the external power grid loses power to improve the reliability of electricity use. The construction of energy storage power stations is restricted by factors such as land use situation, electricity costs, and electricity consumption. Technical and economic feasibility analysis is required before construction. Taking a sewage pumping station as an example, the article introduces the technical scheme and operation mode of the energy storage power station, and analyzes the investment and operation benefits in detail. The static investment can generally be recovered in about 6 years. Water supply and drainage plants can improve their own electricity reliability through the construction and operation of energy storage power stations, and also can reduce a part of operating costs.
