Optimal scheduling method for offshore wind thermal energy storage aggregation system

To address the global energy crisis, developing renewable energy sources, particularly wind power, is a key strategy. Numerous wind farms are under construction or planned. However, the inherent randomness and volatility of wind power lead to inefficiencies such as wind curtailment. To mitigate these fluctuations, wind farms are typically paired with energy storage systems (ESS). In practice, ESS often has redundant capacity. This study proposes using this redundancy to support thermal power units during secondary frequency regulation, enhancing regulation quality and reducing energy waste. We develop and optimize a dispatch method for an offshore wind-thermal-energy storage aggregation system, demonstrating significant improvements in dispatch efficiency and system stability.
