Energy storage optimization configuration method based on transmission congestion containing wind and light access

An energy storage optimization configuration method based on transmission congestion containing wind and light access comprises the following steps of acquiring each unit data; establishing an energystorage capacity two-stage optimization model; taking the economic operation of a system as a target to construct the model without energy storage, selecting a power transmission line which is most likely to generate system congestion and determining an installation node set to be selected; coding an energy storage position and a capacity and randomly forming a first generation population; using the population as a known quantity, using a gradient method to calculate each time output of energy storage in a first-stage function and system operating cost G, using the maximum output of the energystorage as the rated power of the energy storage, and calculating system comprehensive operating cost F; calculating population individual fitness; determining whether the function is converged or reaches the maximum number o
