摘要
微电网技术是构建智慧能源网不可或缺的一环,微电网的发展,必须摆脱对其单一理解的局限,要将其纳入智能能源网系统来综合考虑。该文将微电网问题提升归纳为系统级能量绩效管理和优化设计问题。通过对浙江某选定的区域进行分析,阐述系统级能源优化设计方法。该优化设计方法基于基因算法(genetic algorithm,GA),考虑分析及全寿期分析,目标是建立全寿期经济成本、环境影响最小,效率最大的微电网系统。结果显示,该能源绩效管理方法能有效地对微电网进行优化设计,并对微网中各个组成部分进行分配调度,提高能源利用率,并降低经济成本。
Microgird technology is a necessary step towards smart energy grid. The development of microgrid shall not be understood separately. It is important to comprehensively consider microgrid technology in the context of smart energy grid system. Therefore, the problems of microgrid could be concluded as a system energy performance management and optimization process. Through analysis of a selected area in Zhejiang province, system energy optimum design method is elaborated. The optimum design method is based on genetic algorithm (GA), which considers exergy analysis and life cycle analysis, whose aim is to establish a microgrid system which minimizes the life cycle cost and environmental burdens and maximizes the exergy performance. The result shows that the energy performance management method can effectively optimize the design of the microgrid, distribute and dispatch all parts of the microgrid, and also can increase energy efficiency and reduce economic costs.
