Abstract

The invention discloses a multi-region integrated energy system operation method based on an operation optimization model. The method comprises the steps that 10) a thermal network energy transmission general model is established and simplified into a thermal network energy flow model and a thermal network flow- temperature equation, and a thermal network operation cost model is established; 20) based on a CCHP operation optimization model, the thermal network energy flow model is combined to establish a multi-region integrated energy system operation optimization model; and 30) a multi-region integrated energy system operates according to the operation optimization model established in the step 20). The method can realize thermal energy exchange in different regions, realizes unified scheduling of equipment in different regions, enables the equipment to work in the best condition as much as possible, realizes the optimal work coordination, and improves the energy system economy.

Description

technical field [0001] The invention belongs to the field of operation optimization of comprehensive regional energy systems, and specifically relates to a multi-region comprehensive energy system operation method based on an operation optimization model. Background technique [0002] The increasingly prominent energy and environmental issues have promoted the transformation of human energy utilization. How to improve energy utilization and reduce environmental pollution in order to achieve sustainable energy development is a topic of common concern today. The IES (corresponding to Chinese: integrated energy system) with CCHP (corresponding to Chinese: Combined Cooling, Heating and Power) microgrid as the core unit conducts unified dispatch of grid power, natural gas energy and distributed energy, while meeting various load demands. It improves the economic and environmental benefits of the energy system and is an important direction for the development of the energy system ...
