Research on Energy Storage Regulation Method in DC Microgrid Based on Discrete Fourier Transform

The current DC microgrid energy storage regulation method is easy to produce unbalanced power grid load, and the reliability of regulation results is low. We propose a new DC method for microgrid energy storage regulation based on Fourier transform. Establish grid data topology structure, set a complete subset, to supply the energy for the main space, realize the energy storage data acquisition, establish energy storage system power cut-off, analyze the economic cost, establish the lowest cost, using the discrete Fourier algorithm to solve the hybrid energy storage capacity regulation method, obtain the optimal regulation method. The experimental results show that the energy storage regulation method of DC microgrid based on discrete Fourier transform can effectively solve the problem of unbalanced power grid load power distribution and improve the regulation reliability.
