Abstract

The invention discloses a regional integrated energy system operation optimization method. The method comprises the following steps: S1, establishing an energy network transmission model; s11, establishing a natural gas network model; s12, establishing a thermodynamic network model; s13, establishing an electric-thermal-gas coupling network system model; s2, establishing an economic dispatching model of the regional comprehensive energy system; s3, combining the economic dispatching model of the regional comprehensive energy system with the natural gas network model, the thermal network modeland the electric-thermal-gas coupling network system model, and establishing a mixed integer linear programming model of the regional integrated energy system; and S4, obtaining a result of the mixedinteger linear programming model through a fruit fly optimization algorithm. The coupling relation among the power system, the thermodynamic system and the natural gas system is comprehensively considered, the economic advantage of heat and power cogeneration can be achieved, and the utilization efficiency of regional comprehensive energy is improved.

Description

technical field [0001] The invention relates to the field of energy, in particular to an operation optimization method for a regional comprehensive energy system. Background technique [0002] Energy and environmental issues have become increasingly prominent, which has promoted the transformation of human energy consumption patterns. How to improve energy efficiency, reduce environmental pollution, and achieve sustainable energy development is a topic of common concern today. The regional integrated energy system (RIES) takes the microgrid including combined cooling, heating and power (CCHP) as the core unit, and can uniformly dispatch the power grid, natural gas energy (NG) and distributed generation (DGs). RIES can meet the needs of various loads and improve the economic and environmental benefits of energy systems, which is an important direction for the development of energy systems in the future [1-2]. [0003] At present, the planning and operation of RIES usually t...
