From the perspective of the CES operator, the purpose of installing extra energy storage facility is to increase CES system's profit. The objective function of the upper layer model (24) is to maximize the annual profit of the CES system after installing the Li-ion battery station.
Optimal energy storage planning framework of CES. In this paper, we proposed the optimal operation model of DHS system and power system to evaluate the baseline working point of CHP unit and the expected renewable power curtailment.
In [ 23 ], an optimal sizing planning strategy for energy storage was formulated for maintaining the frequency stability under power disturbance, and a scenario tree model was used to describe the uncertainties of wind power forecast in the optimization framework.
The applications of energy storage for the power system operator are diverse. At present, energy storage has already been widely used in peak-shaving, frequency regulation, back-up reserve, black startup, etc. These functions are mainly provided by pumped hydro storage in China which is mainly invested by the power system operators themselves.
Based on this evaluation results, a bi-layer optimal energy storage planning model for the CES operator is established, where the upper-layer model determines the installed capacity of lithium (Li-ion) battery station and the lower-layer model determines the optimal schedules of the CES system.
Therefore, the optimal energy storage planning method is studied to give advice to the CES operator. The optimal energy storage investment plan should be made with full consideration of existing energy storage resources.
