Study on the day-ahead co-operation strategy of regional integrated energy system including CCHP

Energy is usually used in the form of cool, heat and electricity power in industrial park and town. Different types of energy are often coupled in generation, convention, storage and usage sides, especially with the existence of energy storage devices. Under this background, considering coupling of cold, heat and power in a regional energy system, this paper researches on the day-ahead co-operation strategy of regional combined cool, heat and power (CCHP) system. Based on modelling of typical equipment in the regional integrated system, a day-ahead co-operation strategy is proposed with the objective function to minimize daily operation cost of the CCHP system. The established mixed-inter non-linear programming model is solved by CPLEX mathematical programming software. Case study results demonstrate the feasibility and effectiveness of the proposed co-operation strategy of regional CCHP system.
