Comprehensive energy system for promoting consumption of renewable energy

Abstract

The invention discloses a comprehensive energy system for promoting consumption of renewable energy sources. Energy equipment of the comprehensive energy system comprises a wind turbine generator, a photovoltaic unit, a cogeneration unit, a micro gas turbine, power-to-gas equipment and an electric refrigerator. The optimization method of the integrated energy system comprises the following steps: obtaining the carbon transaction cost of the integrated energy system by using a carbon transaction cost model of the integrated energy system; using the operation cost model of the integrated energy system to obtain the system operation cost of the integrated energy system; c, constructing a target function of the integrated energy system based on the carbon transaction cost and the system operation cost of the integrated energy system; and D, on the basis of the objective function of the integrated energy system, in combination with a constraint condition formed by an energy equipment constraint and an energy balance constraint, constructing a low-carbon economic dispatching model of the integrated energy system containing the power-to-gas equipment. According to the comprehensive energy system, the renewable energy consumption level and the operation economic benefits can be improved.

Description

technical field [0001] The invention belongs to the technical field of optimized operation of an integrated energy system, in particular to an integrated energy system that promotes the consumption of renewable energy. Background technique [0002] At present, with the gradual exhaustion of traditional fossil energy and the increasingly prominent environmental problems, promoting energy structure transformation and carbon emission reduction is an important part of the future national development strategy.
