基于生命周期微网的经济性分析

摘要

针对微网经济分析指标体系不系统、不科学等问题,提出了基于生命周期综合考虑各分布式能源经济运行状况、对环境和不同种类负荷造成影响等因素,确定了各分布式能源等年值投资、拆卸、治污、负荷停电赔偿费用以及碳贸易、可靠性、政府补贴效益等来量化微网成本与效益的经济性指标.通过对算例4种微网方案进行经济性分析,验证了理论可行性,同时研究结果为微网投资决策提供了科学依据.%Because some microgrid economic analyses are less systematic and scientific,comprehensively considering cost of the distributed energy resources (DER) of life cycle (LC),influence of DER on the environment and different kind of loads,etc.,each index value of the microgrid's cost and benefit is quantified.Economic analysis of four microgrid schemes is conducted and reasonable analysis results are attained.At the same time,the research results provide scientific basis for investment decision.
