摘要
以带储能的光伏发电系统为研究对象,通过对系统结构的分析,得到系统各部分之间的能量关系。介绍了各功能模块的控制方法,在此基础上以系统经济效益最大化以及提高负荷利用效率为目标,提出一种能量优化控制方案,并对该方案进行了算例分析。结果表明,该方案可使系统节约用户电费约10%,在保证光伏电能就地有效利用的同时,有效地提高了系统经济性。
Taking photovoltaic generation system with energy storage as research object and by means of analyzing system structure,energy relationship between each part of the system was acquired.Control method for each function modules was introduced and a kind of energy optimization control scheme that aimed at maximizing system economic benefit and impro-ving load use ratio was proposed.Meanwhile,example analysis was carried out for this scheme.The result indicated that this scheme was able to save electric charges about 10% and effectively improve economy of the system at the same time of ensuring spot utilization of photovoltaic power.
