The method comprises steps of firstly carrying out scene division of the active output of distributed renewable energy power generation based on the multi-scene technology, and considering the uncertainty of the active output of the distributed renewable energy power generation; secondly, an active power distribution network source network load storage collaborative optimization model being established with the lowest intra-day comprehensive operation cost of the active power distribution network as the target, and on the basis that only the source load storage collaborative optimization operation model is considered, the load storage collaborative optimization model being established; network reconstruction, reactive power output of a distributed renewable energy power generation inverter and an energy storage inverter and collaborative optimization operation of active power output of distributed renewable energy power generation being also considered, and collaborative optimization operation of active power distribution network source network load storage being realized; and finally, for the active power distribution network source network load storage collaborative optimization model, combining with a particle swarm optimization algorithm to solve a mixed integer programming problem.

Description

technical field [0001] The present invention relates to the technical field of distribution network operation, in particular to a multi-scenario technology-based collaborative optimization method for source, network, load, and storage of active distribution networks, which is suitable for formulating operating strategies for active distribution networks and realizing economic dispatch of active distribution networks . Background technique [0002] The active output of distributed renewable energy generation is uncertain. Compared with the traditional economic dispatch, the economic dispatch of the active distribution network should scientifically and rationally formulate the coordinated optimization operation strategy of the source, network, load and storage to realize the distributed renewable energy. The full consumption of power generation improves the economy of the active distribution network. Therefore, the coordinated optimization operation of source-grid-load-storag...
