Description

technical field [0001] The invention relates to an integrated energy system considering an electric-heat-gas network, in particular to a multi-objective operation optimization method for an integrated energy system considering an electric-heat-gas network. Background technique [0002] The integrated energy system refers to the "regional energy Internet" system that can accommodate the input of multiple energy resources and has multiple output functions and transportation forms. In an integrated energy system, various energy conversion devices and storage devices form a coupling relationship between the input and output of the system. Compared with a single energy system, electricity, gas, oil, heat and other energy sources in a multi-energy system form a complementary relationship in a certain coupling form. , together constitute the energy supply system. In the traditional energy utilization model, the energy system can be divided into power network, thermal network and n...

Problems solved by technology

However, the traditional energy supply and utilization method that separates electric energy, thermal energy, and natural gas dispatch and supply does not consider the connection between the electric power network, natural gas network, and thermal network, and cannot fully explore their respective energy supply advantages and potentials, reducing the flexibility of the energy supply model. sex
