Abstract

The invention relates to a working state evaluation method for a multi-energy flow system based on an energy network equation. The method comprises: S1, heat energy and electric energy are used for jointly heating N independent spaces, and an energy network is established; S2, an energy network equation set is established for the energy network according to the generalized Kirchhoff intensity lawand the generalized Kirchhoff broadening law; S3, combining constraint conditions of the energy network equation set and the energy system to form a complete equation set; and converting the physicalquantities of different units in the energy network equation set into dimensionless parameters by adopting a per unit system calculation method, and uniformly solving to obtain the working state of each unit device. For a complex energy network, a uniform model and a uniform energy network equation are established and solved by using a scheme method, so that the working state of each device in thenetwork can be conveniently obtained.

Description

Technical field [0001] The invention relates to the technical field of integrated energy system analysis, in particular to a working state evaluation method of a multi-energy flow system based on an energy network equation. Background technique [0002] The use of renewable and clean energy such as wind power and photovoltaics has become an inevitable trend. These renewable energy sources are highly uncertain, and the power generation is difficult to control, and access to the grid is likely to cause grid fluctuations. Therefore, only the power grid as the carrier of energy transmission has gradually been unable to meet the demand. Under this circumstance, the Energy Internet, which transmits energy in multiple forms of electricity, heat, cooling, and gas, has its advantages. At present, there are more and more demonstrations of the Energy Internet. Among the above-mentioned multi-energy networks, the combined heat and power network is currently developing the fastest. Since the...
