Research on Energy Station System Design Based on Substation Function Expansion

In integrated energy supply systems, energy stations play an important role as key facilities for the provision of energy services to users. Based on the existing substation facilities in the Power Grid, the construction of energy stations can realize the coordinated supply of various energy sources with electric power as the link. In this paper, an energy station construction method based on multi-energy conversion and storage equipment is proposed, the operation mode of the energy station is analyzed with the case of 35kV substation expanding to a new type of energy station. The economic benefits of the new energy stations under the influence of different power purchase prices are analyzed by considering the indexes of primary efficient energy use and payback period of investment.
