摘要
从用电侧的能源条件和负荷需求入手,设计规划了智能微网主要发电单元的装机容量,并从经济性和低碳化两个方面分析了智能微网运行的效益形成机理,进而利用低碳经济要素将两方面效益统一,提出了低碳综合效益的概念。结合智能微网的建设成本,建立了智能微网运行的低碳综合效益分析模型,阐述了以低碳综合成本最低为目标的智能微网日前调度原则,并依据典型的智能微网设计方案所提出的模型对智能微网的投资收益情况进行了分析。结果表明:智能微网的运行方式与传统电网相比,有着很大的低碳综合效益优势;参与到电网互动的智能微网,能够发挥其成本调节作用和灵活运行能力;未来通过降低分布式能源的发电成本,优化电力市场电价系统,加快低碳经济的开展,可达成智能微网运行的经济性与低碳性的高度统一。
Beginning with local renewable energy source situation and load demand at consumer side, the installed capacities of generating units in smart microgrid were planned; considering economic effect and low-carbon effect the benefit formation mechanism of smart microgrid operation was analyzed, and then through integrating the benefits from the two aspects by low-carbon economic elements a concept of low-carbon integrative benefit was proposed. Combining with construction cost of smart microgrid, an analysis model of low-carbon integrative benefa from smart microgrid operation was built and the principle for day-ahead dispatching of smart microgrid, in which the minimum low-carbon integrated cost was taken as objective, was expounded, and based on typical design case of smart microgrid the income from investments of smart microgrid was analyzed by the proposed model. Analysis results show that comparing with operation modes of traditional power grid, the operation modes of smart microgrid possesses evident superiority in low-carbon integrative benefit; smart microgrid participating the interaction with traditional power grid can play its role in cost adjustment and flexible operation; the operational economy and the low-carbon effect of smart microgrid can be highly unified by means of decreasing the generation cost of distributed energy resources, optimizing pricing system in electricity market and quickening the development of low-carbon economy in the future.
