Mixed Energy Storage Capacity Configuration Strategy There are self-consumption factors in the active frequency support operation process of the mixed energy storage station. From the literature we inferred that the rated power of the energy storage system surpasses the current system’s target.
This means the rated power of the energy storage should be capable of meeting the maximum power requirement in the T period, independent of the charging state, to achieve an active power balance. Therefore, the power constraints for energy-type, hybrid-type, and power-type storage are as follows:
According to the required power for frequency regulation for energy storage, the power and capacity configuration of the hybrid energy storage is feasible. 3. Capacity Configuration Method for Hybrid Energy Storage
The fluctuation of renewable energy resources and the uncertainty of demand-side loads affect the accuracy of the configuration of energy storage (ES) in microgrids. High peak-to-valley differences on the load side also affect the stable operation of the microgrid.
The configuration ratios of RESs have significant impacts on the aggregated power generation, thus influencing the planning results at the SW level and the system's techno-economic performances.
This article will delve into the importance and necessity of capacity configuration when energy storage stations participate in the regulation of primary frequency. Currently, there have been some studies on the capacity allocation of various types of energy storage in power grid frequency regulation and energy storage.
