Collaborative Optimal Configuration of Electric Power Conversion Equipment and CCHP Equipment in IES Considering Variable Working Condition
In order to further improve the operation efficiency of integrated energy system and ensure the reliability of integrated energy supply, this paper presents a complementary optimal allocation method of energy conversion equipment and CCHP equipment in IES considering the characteristics of variable working conditions. Firstly, considering the complementarity of CCHP system and power conversion equipment, the equipment configuration strategy is proposed, the integrated energy supply system is constructed. Then, taking the lowest annual total cost of IES as the optimization objective and considering the reliability constraints of N-1 energy supply, a bilevel optimization model of equipment configuration is established and solved by differential evolution algorithm. The validity of the model and the feasibility of the scheme are verified by an example.
