Real-time Control Strategy for Wind-solar-storage Industrial Park Based on Variational Modal Decomposition

The large-scale access of renewable energy will make the grid structure become increasingly complex, and the risk of operation and control will increase dramatically. In this paper, a real-time control strategy for wind-solar-storage industrial park based on variational modal decomposition is proposed with wind-solar industrial park as the research object: Analyze the deviation power signals of the wind-solar-storage industrial park contact line using variational modal decomposition (VMD) calculations and allocate the power of the hybrid energy storage system to smooth out the power deviation of the park contact line. Simulation results show that the method can better fit the current power spot market operation rules in China, effectively improve the planned power deviation and various assessment indicators, and improve the economic operation level of the park.
