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.
Also, the existing widely-used method in energy storage planning, that embeds the system frequency response model into the optimization model to deal with inertia shortage demand, is unfeasible to be directly used in the CES business model due to the data confidentiality problem.
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.
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.
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.
One of the feasible solutions is deploying the energy storage system (ESS) to integrate with the energy system to stabilize it. However, considering the costs and the input/output characteristics of ESS, both the initial configuration process and the actual operation process require efficient management.
