Embodiment Construction
[0111] The present invention proposes a comprehensive thermoelectric system scheduling method based on the tightening McCormick method, which is described in detail below in conjunction with the accompanying drawings and an embodiment:
[0112] The present invention proposes a comprehensive thermoelectric system scheduling method based on the tightened McCormick method. The method first establishes the basic model of the district heating system based on volume regulation and reconstructs it, and then establishes the power system model and the energy model respectively. According to the three A model is established to establish a combined heat and power system joint scheduling model composed of objective functions and constraints, and transform the joint scheduling model into a convex McCormick model. The McCormick model is converted using the segmental McCormick technique, and the converted model is solved using the boundary shrinkage algorithm. , to get the final integrated he...

The invention provides a comprehensive thermoelectric system scheduling method based on a tightening McCormick method, and belongs to the technical field of thermoelectric system joint scheduling. According to the method, a basic model of a regional heat supply system based on quantity regulation is established and reconstructed, then an electric power system model and an energy model are established, a comprehensive thermoelectric system joint scheduling model composed of an objective function and constraint conditions is established according to the three models, the joint scheduling model is converted into a convex McCormick model, the McCormick model is converted by using a segmented McCormick technology, and the converted model is solved by using a boundary contraction algorithm to obtain a final integrated thermoelectric system scheduling scheme. According to the invention, the calculation complexity can be reduced, and the feasibility and optimality solutions meeting actual operation requirements can be quickly obtained, so that the method is used for comprehensive thermoelectric system scheduling based on heat supply network quantity adjustment.
Description
technical field [0001] The invention belongs to the technical field of joint dispatching of thermoelectric systems, and particularly proposes a dispatching method for comprehensive thermoelectric systems based on the tightening McCormick method. Background technique [0002] The electricity system is an important part of the country's energy supply, while heating also plays a key role in the energy system. The International Energy Agency found that more than half of global energy use is used for heating. In terms of heating, district heating systems are predominantly used in high population density areas, while other heat alternatives (such as individual heat pumps, gas boilers, solar and electric heating) are often used in low population density areas. The proportion of these heating methods varies in different countries and regions, and district heating among them has proved to be more energy efficient. [0003] Electricity and heat can be produced simultaneously with ce...
