Abstract

The comprehensive energy system optimization operation model considering network constraints proposed by the invention belongs to the field of energy system analysis. The present invention establishes an integrated energy system optimization operation model with the power system, gas supply system, and district heating system as the main body. The model aims at minimizing the operating cost of the integrated energy system, and considers the power network, gas network, and thermal network. The characteristic constraints can ensure the balance of energy supply and demand of the integrated energy system and the security of network operation, and have practical value and guiding significance for the economic and safe operation of the integrated energy system.

Description

technical field [0001] The invention belongs to the field of energy system analysis, and is specifically an optimized operation model of an integrated energy system considering network constraints. Background technique [0002] The integrated energy system refers to a large energy system with electricity, heat, and gas systems as the main body. Different types of energy have complex coupling relationships in each link of circulation, and then form an interrelated organic whole, so it can be called an integrated energy system. [0003] At present, in terms of energy system optimization and operation, my country's power, heat, gas and other energy systems are all in a state of separate management, without considering the coupling effect of energy and the overall efficiency of the energy system, so it can only achieve "local energy" within each energy system. Optimum” cannot achieve the “global optimum” of the overall energy system. In addition, electricity, heat, and gas usual...
