A Planning Approach for Grid-side Energy Storage Considering Load-peak in the Urban Power Grid

With the continuous development of China's economy and the acceleration of urbanization, the load level of urban power grid is increasing and the peaking pressure is growing year by year. Grid-side energy storage using battery storage technology has the characteristics of fast response, high flexibility and low loss. Based on this, this paper proposes a grid-side energy storage planning considering the urban power grid peaking demand. The method first constructs a multidimensional evaluation system of urban power grid load level according to the evaluation index of urban power grid load level to realize the perception of urban power grid peaking demand, and then establishes the grid-side energy storage planning model and distribution network revenue model, respectively. Finally, simulations are performed in a modified IEEE 14 node system to demonstrate the feasibility of the proposed method.
