The power system peak load regulation is conducted by adjusting the output power and operating states of the power generating units in both peak and off-peak hours.
To explore the application potential of energy storage and promote its integrated application promotion in the power grid, this paper studies the comprehensive application and configuration mode of battery energy storage systems (BESS) in grid peak and frequency regulation.
The proposed method was verified in a real prefecture-level urban power system in southwest China, and its modified test systems. The case studies demonstrated the intrinsic capacity of the thermal units in the system peak load regulation.
Accordingly, the proportion of electricity generated by local thermal power units has declined to 40% in Shanghai. Referring to the peak load regulation capacity defined in , the decline of local thermal power generation leads to a decrease in the local peak load regulation capacity.
An integrated optimal scheduling model for power system peak load regulation with a suitable rolling optimization strategy is proposed. A real prefecture-level urban power system in southwest China and its modified test systems are used to test and verify the validity and effectiveness of the proposed methodology. 1. Introduction
