Abstract

To realize the efficient and economic consumption of new energy in the multi-energy complementary system, this paper studies the economic effects of the multi-energy coupling system based on the perspective of the value chain, and constructs a complex value chain system with wind and solar power subsystem and thermal-hybrid energy storage subsystem as the key subsystems—electro-hydrogen coupling system (EHCS). Firstly, a value co-creation analysis framework to promote the economic effects of EHCS under the energy internet is analyzed. Secondly, a bi-level model to optimize capacity allocation and operations is constructed. Based on the typical scenarios generated by R-Vine Copula function and K-medoids, the upper determines capacity allocation with maximum net benefit. The lower level combines the operating characteristics of THESS to minimize the operating cost and wind and solar curtailment. The bi-level optimization is solved by GUROBI and MOBWO-VIKOR method. Finally, case studies are conducted to verify the validity and feasibility of the model. The results show that the proposed model can achieve new energy consumption of 97.5 % while the net benefit to 1270.18 billion CNY and reduce the operating costs over the planning period. This study can provide useful suggestions for the investment and construction of multi-energy coupling projects.
