Research on Optimization Model and Method of a Multi-energy Complementary Combined Heat and Power System

With the increasing energy consumption and the increasingly severe environmental situation today, it is urgent to actively carry out the transformation and upgrading of energy consumption. The multi-energy complementary integration system can make the complementary advantages among various forms of energy, and make the whole energy utilization system improve in many aspects, such as energy consumption, economic cost and environmental benefits. This paper constructs a multi-objective optimization model containing both economic and environmental benefits, and the cogeneration system source side load as the constraint condition, the dynamic-objective method (DOM) based on the improved algorithm of constraint mechanism for source network collaborative optimization.Through the optimal combination of units and reasonable load distribution, the overall economic efficiency of the system can be optimized.
