[0019] Specific implementation plan
[0020] Aiming at the instability problem of wind power grid connection, this paper proposes a hybrid energy storage capacity configuration method to suppress wind power instability. First, the overall average empirical mode decomposition is performed on the unbalanced power of wind power, and the filter order d is selected based on the cumulative average of the standardized modes. 1 , D 2 , Divide the compensation order of different energy storage equipment, and determine the power and capacity configuration of different energy storage equipment; then, introduce the gradient method to optimize the filter order, and compare the equipment cost of different filter orders, and select the cost The smallest filter order is used as the power and capacity allocation standard; finally, the opportunity constraint model is established based on the volatility of electricity prices, and the improved quantum genetic algorithm is used to calculate the econom...
