New energy consumption optimization method and system suitable for cities and counties

The invention discloses a new energy consumption optimization method and system suitable for cities and counties. The method comprises the following steps: acquiring operation data of source, network, load and storage side resources in cities and counties; calculating a typical scene of theoretical to-be-analyzed level annual generation power of the new energy station in the city and county region; establishing a new energy-energy storage optimization model in the city-county region by taking maximum new energy consumption electric quantity in the city-county region as an optimization target; taking the minimum comprehensive optimization cost as a target, considering key power transmission line constraints between city and county regions, and establishing a source network load storage coordination optimization model between the city and county regions; according to a source-network-load-storage coordinated optimization result, determining a source-network-load-storage coordinated optimization scheme between c
