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.
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.
Energy storage equipment can realize the input and output regulation of electric energy at different time scales, which can effectively improve the operating characteristics of the system and meet the power and energy balance requirements of a smart grid. The application of different energy storage technologies in power systems is also different.
Energy storage systems play a major role in smoothing the fluctuation of new energy output power, improving new energy consumption, reducing the deviation of the power generation plan, and improving the safe operation stability of the power grid. Specific classification scenarios are shown in Figure 4.
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.
