摘　　要：针对综合能源微网涉及多种能源相互耦合、各能源负荷供应能力难以量化评估的问题,提出了综合能源微网可行供能区间及可靠供能区间评估方法。首先,以综合能源微网为研究对象,结合能源集线器模型构建了典型微网系统模型,并提出综合能源微网供能能力概念。其次,构建综合能源微网可行供能区间模型,并进一步考虑供能可靠性约束,构建综合能源微网可靠供能区间模型。再次,基于NSGA-2多目标优化算法提出综合能源微网可靠供能区间模型的求解方法及流程。最后,通过算例验证了所提模型和方法的有效性和实用性。Aiming at the problems that the energy supply of multi-energy microgrid involves in coupling of multiple kinds of energy sources and the energy supply capability of each energy load is hard to be quantificationally evaluated.The evaluation method of feasible and reliable energy supply intervals for multi-energy microgrid are proposed.Firstly,taking the multi-energy microgrid as the research object,a typical model of microgrid system is constructed based on the energy hub model,and the concept of energy supply capability of multi-energy microgrid is proposed.Secondly,the model of feasible energy supply interval of multi-energy microgrid is constructed,the constraints of energy supply reliability is further considered,and the model of reliable energy supply interval for multi-energy microgrid is built.Thirdly,based on NSGA-2 multi-objective optimization algorithm,the solution method and process of the model of reliable energy supply interval is proposed.Finally,the effectiveness and practicability of proposed models and methods are verified by a case.
