In the energy storage planning model, a bi-level planning model that combines planning and operation should be used to consider numerous factors such as new energy output uncertainty, economy, environmental protection, and technology.
Then, the fuel economy and battery degradation are evaluated to return feedback value to each sizing point within the hybrid energy storage system sizing space, obtaining the optimal sizes for the battery and the SC by comparing all the values in the whole sizing space.
As can be seen in Table 3, for the power type and application time scale of energy storage, the current application of energy storage in the power grid mainly focuses on power frequency active regulation, especially in rapid frequency regulation, peak shaving and valley filling, and new energy grid-connected operation.
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.
