Abstract
- The optimal operation strategy of an integrated energy system is an important means to ensure the economic and stable operation of the system. Given the problem of economic-flexible multi-objective coordination optimization of the integrated energy system (IES), this paper selects the typical electric-gas-thermal energy system framework and builds mathematical models of system equipment. Taking account of system operation cost and flexibility, this paper proposes IES multi-objective operation optimization strategy considering energy storage life characteristics. The optimal solution of multi-objective problems uses the ε-constraint method, which transforms the secondary objective function into a constraint and then puts it into the solution frame to obtain the Pareto frontier. The optimal operation plan of the IES is determined through fuzzy decision-making. Finally, the proposed model and method are proved feasible by example simulation.
