摘要(Abstract):
合理的综合能源系统优化运行策略是保证系统经济稳定运行的重要手段。针对综合能源系统经济-灵活多目标协调优化问题,选取典型电-气-热能源系统框架并建立系统设备数学模型,综合考虑系统运行成本和灵活性,提出考虑储能寿命特性的综合能源系统多目标运行优化策略。多目标问题的优化求解利用ε约束,将次要目标函数转化为约束后加入求解框架,得到该问题的Pareto前沿,通过模糊决策确定综合能源系统的最佳运行方案。最后,进行算例仿真验证证明了所提模型与方法的可行性。
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.
