Abstract: We consider using a battery storage system simultaneously for peak shaving and frequency regulation through a joint optimization framework, which captures battery degradation, operational constraints, and uncertainties in customer load and regulation signals.
Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
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.
Here, multiple modes of action for peak and frequency regulation are established and other peak and frequency regulation units present in the grid beside the BESS are considered that can assume the corresponding regulation functions. Therefore, no additional frequency or peak-to-valley differences are triggered in the different modes.
In Ref. , an optimal control strategy for ES participation in frequency regulation was proposed based on actual market settings and an accurate battery-aging model. In Ref. , a bi-level optimization problem model was proposed, considering the application of ES in frequency regulation of power systems.
