Abstract:For wind power storage systems during operation control， excessive fluctuations in the charge/discharge power amplitude of the energy storage system can directly impact the system's operational control effectiveness. To address this， an optimized operation strategy for energy storage systems to mitigate wind power fluctuations is proposed. Based on the structure of the energy storage system， relevant factors affecting system optimization are analyzed in detail and incorporated as constraints in the system operation control process. Aiming to reduce the output volatility of the energy storage system， corresponding objective functions are formulated， and a look-ahead period is introduced， further proposing an advanced control strategy for optimized operation of the energy storage system to achieve its optimal performance. Experimental results demonstrate that the proposed method effectively suppresses the system’s charge/discharge frequency， maintains storage capacity at 69%， and confines power fluctuation within the desired target range， basically consistent with the expected target range. This method exhibits superior performance in system optimization and operational control.
