Abstract

The invention discloses a standardized construction method of an integrated energy system energy hub model. According to the method, a complex integrated energy system energy hub model is divided into simple integrated energy system energy hub models, coupling matrixes of the simple integrated energy system energy hub model are orderly multiplied, and finally a coupling matrix of the whole complex integrated energy system energy hub model is calculated. In the construction process of the coupling matrix, the energy circulation is taken into consideration by means of adding a limit equation to the integrated energy system energy hub model, and the mismatch of the coupling matrixes of the different simple integrated energy system energy hub models is avoided through adding virtual energy conversion equipment. Meanwhile, in the construction matrix modeling process, the concepts of energy storage equipment location and energy side demand response are extended, thereby enabling the energy storage and energy side demand response of an electric power system to be extended to the integrated energy system.

Description

technical field [0001] The invention belongs to the field of model construction and optimization of a comprehensive energy system, and relates to a standardized construction method of an energy hub model of a comprehensive energy system. Background technique [0002] The energy crisis caused by the decrease of traditional non-renewable energy and the damage to the environment caused by the use of traditional non-renewable energy are driving people to reconsider the existing energy production, consumption and storage models. In order to solve this energy dilemma, governments of various countries have increased research funding and policy support for the production, distribution and consumption of renewable energy, and reached a consensus on the energy Internet and the overall planning of multi-energy systems. However, compared with the traditional power system, the integrated energy system is more complex and large. This has caused great difficulties in modeling the energy h...
