摘要
微网技术是新能源及可再生能源并网发电规模化应用的有效途径,可在一定程度上解决孤立海岛或偏远地区的供电问题。利用柴油发电机作为孤岛型微网的主要能源支撑时,其型号选取、容量确定等因素均直接对系统的供电可靠性产生影响,并间接影响系统的经济性能。本文以某海岛孤岛型微网系统为例,提出了柴油发电机设备的优化配置方法。经研究分析表明,在兼顾考虑微网系统经济效益、可再生能源利用比例、污染物排放以及柴发寿命等因素的情况下,可得到具有最佳综合性能的柴发优化配置结果。
Microgrid is an efficient approach for taking advantage of renewable energy resources which can to a certain extent ensure reliability of the important load isolated from the power supply in island or remote area. How to choose the model and confirm the capacity of the diesel generator as a primary energy support in an islanded microgrid has a direct impact on the reliability of power supply and on the economic performance of the system. Based on an island microgrid system as an example,this paper puts forward a method to optimize the performance of diesel generator. Simulation results show that the integrative performance using the optimizing configuration proposed is excellent while taking the microgrid economic performance,the proportion of the renewable energy resources,pollutant-emission and the diesel generator life into considering.
