Recently, the State Intellectual Property Office announced the patent “Microgrid Operation Planning Method and Systemâ€. The applicants are China Southern Power Grid Corporation Power Grid Technology Research Center, China Southern Power Grid Science Research Institute, and North China Electric Power University.
The invention relates to a microgrid operation planning method and system. The method comprises: obtaining parameter information of the distributed unit and the energy storage system in the micro grid, and using the lowest total operating cost of the micro grid in the planning period as the objective function, constructing the micro grid planning model including the energy storage system according to the parameter information; obtaining the pre-built The model constraints, the planning model is solved according to the model constraints; the optimal solution of the planning model is obtained, and the corresponding microgrid operation planning scheme is obtained according to the optimal solution.
Based on the solution of the invention, the planning scheme with the lowest total operating cost of the microgrid containing the energy storage system can be obtained, and the actual operation effect of the planning scheme is improved.
