摘要
准确计算光伏发电系统的输出功率,对光伏发电系统发电量的监管和光伏并网系统与电网调度、电力负荷等的配合问题具有重大意义。根据光伏发电系统的结构和工作原理,提出了光伏发电系统输出功率计算方法,可以计算任意太阳辐射量、环境温度、系统结构下的光伏发电系统输出功率。通过与真实光伏电站运行数据的比对,结果显示了光伏发电系统输出功率计算方法的适用性与准确性。
Accurate calculation of output power of the photovoltaic system is critical to the photovoltaic system energy management and satisfactory coordination between the photovoltaic system and electricity control dispatch as well as the power load. The current study develops a calculating method for the photovoltaic system output power based on the structure and working principle of the photovoltaic system, by which the output power can be computed at any solar irradiation level, ambient temperature, parameters of the photovoltaic module. By comparing the calculated data with the authentic operating data of PV station, the suitability and accuracy of this calculating method is demonstrated.
