Optimal Configuration of Energy Storage Capacity considering Generalized Energy Storage Resource Dispatching

The rapid development and application of generalized energy storage resources including fixed energy storage and adjustable loads have brought challenges to the safety and economic operation of industrial parks. In this paper, a two-layer planning strategy for energy storage capacity considering generalized energy storage resource control is proposed for an industrial park with photovoltaics (PV) and adjustable loads. Firstly, considering the operating characteristics of generalized energy storage resources, the response models are established. Secondly, through the dispatching of adjustable loads and reducible loads, the PV output is fully absorbed, the operating cost is reduced, and the peak shaving demand is satisfied. Then, the park’s energy storage capacity is configured to improve economy and stabilize load fluctuation. Finally, the simulation result shows that the proposed method can mobilize load-side resources and cut the park’s operating cost.
