The invention relates to a short-term combined optimization and scheduling method for water, wind, and wind, which takes into account the uncertainty of new energy output, and belongs to the technical field of multi-energy complementary coordination and scheduling. This method proposes a method for generating typical combined output scenarios in the future with the predicted output of new energy as the input condition, and uses historical statistical information to convert the single deterministic output forecast of new energy into a variety of actual possible output scenarios and corresponding probabilities. Based on this, a stochastic expected value peak-shaving model for multi-scenario water-solar joint dispatch is constructed. And use the optimization software to solve the model, and finally obtain the hydropower operation plan. The invention can effectively deal with the influence of the uncertainty of new energy output on the hydropower operation plan, is beneficial to improve the reliability of the hydropower plan, and provides a new technology for the combined optimization and dispatching of water and wind power in a high-proportion renewable energy power system dominated by water bills way.
Description
technical field [0001] The invention belongs to the technical field of multi-energy complementary coordination and dispatching, and particularly relates to a short-term combined dispatching method for water, wind, and wind in a hydropower-dominated high-proportion renewable energy power system. Background technique [0002] With the increasing problems of resource shortage, climate change, and environmental pollution, prioritizing the development and utilization of renewable energy such as hydropower, wind power, and solar energy is an important way to promote environmental protection and reduce dependence on fossil energy, which is also the consensus of the international community. Driven by relevant national policies, there have been a number of high-proportion renewable energy grids dominated by hydropower in my country, of which Yunnan and Tibet are the most typical. Due to the unschedulable characteristics of new energy (wind power, photovoltaic), the grid often adopts ...
