Then, a joint scheduling model is proposed for hybrid energy storage system to perform peak shaving and frequency regulation services to coordinate and optimize the output strategies of battery energy storage and flywheel energy storage, and minimize the total operation cost of microgrid.
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
For energy-type storage system, like pumped storage and compressed air storage, the peak-to-valley price ratio is very sensitive in energy arbitrage. For power-type storage system, like flywheel storage, the mileage ratio is in leading position in auxiliary service benefit by mileage.
Here, we focused on this subject while conducting our research. The multi-timescale regulation capability of the power system (peak and frequency regulation, etc.) is supported by flexible resources, whose capacity requirements depend on renewable energy sources and load power uncertainty characteristics.
Usually, peak shaving and frequency regulation service is a short-term scheduling problem. Considering the characteristics of MG load curve and power grid TOU price curve, this section selects the data of 12:00 for simulation research, which is both the peak load period and the peak electricity price period.
4.2.1. Energy storage power correction During peaking, ES will continuously absorb or release a large amount of electric energy. The impact of the ESED on the determination of ES capacity is more obvious. Based on this feature, we established the ES peaking power correction model with the objective of minimizing the ESED and OCGR.
