随着光伏发电在电网中穿透功率水平的逐渐提高,光伏发电的容量价值逐渐成为电网规划中关注的新热点,但目前固定式并网光伏阵列朝向与倾角的选取仍以能量价值最大为依据,极大地限制了光伏发电的综合价值。针对此问题,文中建立了光伏阵列的出力模型,分析了朝向与倾角对光伏发电能量价值和容量价值的影响,提出了基于综合价值的光伏阵列朝向与倾角优化方法,并通过仿真算例验证了方法的有效性。

As the penetration of photovoltaic(PV) generation increases rapidly in recent years,capacity credit of PV is becoming one of the hot topics in power system planning.However,the optimum orientation and tilted angel of grid connected fixed PV arrays are still obtained according to the principle of maximum energy value,which limits the comprehensive value of PV generation.The power output model of PV arrays is established first,followed by the effects of orientation and tilted angel on energy value and capacity value analysis.Finally,a novel optimization method for orientation and tilted angel according to the principle of maximum comprehensive value is proposed,and its effectiveness is proved by tests in a simulation system.
