Abstract

The invention discloses a method and device for power supply and seasonal energy storage planning. The method includes: evaluating the regional demand-side response potential according to the maximum load of each industry, the peak-shaving ratio of each industry, user participation and the maximum load simultaneous rate; obtaining Regional new energy power generation output limit scenarios and regional new energy power generation output typical scenarios; determine the objective function and constraints, and establish a planning model with the goal of minimizing the total system cost according to the objective functions and constraints; set the upper limit of seasonal energy storage capacity constraints; Input the typical scene of the regional new energy power generation output into the planning model, solve the planning model according to the regional demand side response potential, and obtain the optimal solution; and check the robustness of the optimal solution to obtain Power and seasonal energy storage planning solutions. The present invention improves the robustness of planning results by considering extreme scenarios.

Description

technical field [0001] The invention relates to the technical field of electric power planning, in particular to a method and device for power supply and seasonal energy storage planning. Background technique [0002] Compared with traditional fossil energy power generation, new energy power generation has randomness and volatility, and large-scale access will bring all-round new challenges to the power system. In order to meet the demand for new energy regulation, large-scale energy storage must be developed. Among them, seasonal energy storage can support the energy translation of electric energy for a long time, thereby solving the long-term consumption problem of high proportion of new energy. Compared with other seasonal energy storage, hydrogen energy is the best way for large-scale and long-term energy storage. At least 23 provinces across the country have released hydrogen energy development plans, and more than one-third of central enterprises are formulating the ...
