Problems solved by technology
Although the application of different data mining techniques determines the different geometric appearances of data-driven uncertain sets, it is common to form convex polygons with multiple vertices to achieve the closest distribution of historical data and reduce unnecessary waste of resources. The above method Although it can improve the defects of traditional box-type uncertain sets, but the calculation efficiency is low due to the complex construction of uncertain models and too many geometric vertices

The invention discloses a method for solving a robust unit combination model of an electric heating comprehensive energy system. The method comprises the following steps: firstly, establishing a robust unit combination pre-scheduling model of the electric heating comprehensive energy system based on optimal economic scheduling; solving the established pre-scheduling model based on the prediction value of the wind power, and obtaining an operation strategy with optimal economic benefit and an admissible domain of the wind power and the environment temperature; judging whether the spatial correlation of the wind power is mined or not, and if yes, establishing a data driving uncertainty set based on the wind power correlation and eliminating invalid vertexes; establishing an electric heatingcomprehensive energy system robust unit combination rescheduling model; solving the rescheduling model based on a data-driven uncertainty set, and obtaining the worst scenes of wind power and environment temperature and the corresponding power unbalance amounts; judging whether the power unbalance amount obtained in the step 5 meets a convergence condition or not; and if so, considering that the operation strategy is feasible, and ending iteration. The method can effectively improve the calculation efficiency on the premise of ensuring that the operation strategy is not conservative.
Description
Technical field [0001] The present invention relates to the technical field of electrothermal integrated energy systems, and more particularly to a solution method of a combination model of a robust unit of an electric heat integrated energy system. Background technique [0002] In the winter, in the northern my country, there is a concentrated production capacity of thermoelectric production, and the installed capacity of the thermoelectric gauge is growing, and the total amount of thermal power appliance is approximated. At the same time, in the northern my country has rich wind resources. In winter, wind power production capacity has grown rapidly, and the routine "thermal power supply" working model of the thermoelectric network is not conducive to the wind power in the same time, there are many The factors jointly promote the exploration and development of electrothermal integrated energy system scheduling model centered on electrothermal concentration. [0003] The explorat...
