In order to effectively control multi branch flexible interconnected distribution networks, a multi time scale hierarchical control method for distribution networks using multi end flexible interconnection devices is proposed. Install high-precision multi terminal flexible interconnection devices, collect traveling wave signals from the distribution network, and use reconstructed wavelet coefficients to denoise the signals. Predicting loads under the application of multi terminal flexible interconnection devices and constructing a collaborative control model for flexible distribution flexible interconnection devices; Establish multi time scale constraints and use population genetic algorithm to solve the multi time scale hierarchical control model of the distribution network, achieving multi time scale hierarchical control of the distribution network. The test results show that this method can maintain the stability of the distribution network load, reduce the network loss rate, and improve the efficiency of load control response.
