The multi-power joint optimized scheduling operation method comprises the steps of: establishing an optimized unit combination scheduling operation method model according to a set number and operation parameters ofthermal power generating units, a set number and operation parameters of wind power generating units, a set number and operation parameters of nuclear power generating units and a set number and operation parameters of pumped-storage unit in a power system, and load data and wind power forecasting data of the power system; and calculating a unit joint operation result with maximum power grid revenue and maximum wind power consumption according to the optimized unit combination scheduling operation method model. The multi-power joint optimized scheduling operation method takes power grid scheduling cost minimization and wind power consumption maximization as optimization goals, and can meet the requirements for power grid revenue maximization and wind power consumption maximization.

Description

technical field [0001] The invention relates to the technical field of power grid control systems, in particular to a multi-power source joint optimal scheduling operation method based on wind-core coordination. Background technique [0002] In recent years, energy and environmental issues have become increasingly prominent. Emerging energy represented by wind power and nuclear power has become an important direction of energy development because of its non-polluting, no greenhouse gas emissions, and renewable characteristics. As a special power source, the pumped storage unit pumps water when the load is low and generates power when the load is peak. As the installed capacity of my country's power system continues to increase, the types of power sources and load types continue to diversify, and the task of peak regulation in the daily operation of the power grid and the task of accommodating large-scale clean energy has become more and more difficult. The regulation of ther...

Problems solved by technology

[0003] Through the search of the existing literature, it is found that there are relatively few studies on the optimal scheduling operation mode of multi-power sources based on wind-nuclear coordination, and there are the following four problems: In the dispatching model, many studies take the lowest overall operating cost of the power plant and the least fuel consumption as the optimization goals; in the joint dispatching model, most nuclear power units always maintain the base load operation state; the joint dispatching model has high accuracy in dealing with wind power uncertainty, but It is difficult to realize in practice; in the joint joint dispatching model, the problem of exceeding the limit of the reservoir of the pumped storage unit is less considered
