Intelligent Optimization Algorithm of Active Distribution Network Based on Load Storage Cooperative Optimization of Source Network

Since the beginning of the new century, the rapid development of human science and technology has increased the productivity and energy consumption, which has led to the depletion of traditional fossil energy and accelerated environmental pollution. According to the national strategic plan for future energy development, more distributed generation will be connected to the distribution network in the future, which will transform the urban distribution network from the traditional load-side network to the multi-source network with two-way power flow, which will bring challenges to the operation of the urban distribution network. The distribution network dispatching operation of active distribution network will not only be the operation and adjustment of the sectional switch, but also consider the multi-source optimal dispatching control after a large number of distributed power sources, flexible loads and energy storage devices are connected. By controlling the voltage of optical storage and parallel node, the optimal configuration of optical storage access location and capacity is realized. Based on the operation characteristics of active distribution network, this paper puts forward the overall architecture and application framework of multi-source cooperative optimal dispatching, and studies the key technologies such as multi-source data fusion, rapid simulation of active distribution network, multisource cooperative optimal dispatching strategy and evaluation of multi-source cooperative optimal dispatching strategy.
