摘要

提出了一种新的光伏发电系统在实际天气条件下的瞬态现象模拟方法，为光伏发电系统的研究与开发提供了一种简便、经济的分析方法，同时考虑了电池的种类、系统容量和所使用的变换器系统。本文模拟了与电源变流器相连的光伏阵列。描述了光伏阵列在实际天气条件下输出电流的瞬态变化，并利用PWM开关宽度对直流/交流变换器输出到公用电网的电流进行了分析。并将光伏发电系统的MPPT控制与系统仿真相结合。仿真结果验证了所提仿真方案的有效性。结果表明，在相同天气条件下，对光伏发电系统的效率或可用性和稳定性进行成本效益验证以及对MPPT等各种控制方案进行比较研究是可能的。

A study on the simulation scheme for utility interactive PV generation systems

A novel transient phenomenon simulation method for PV power generation system under the real field weather condition (SPRW) has been proposed, and the research and development of PV power generation system is expected to be able to analyze easily cheaply under various conditions with considering the sort of cell, the capacity of system and the used converter system. In this paper, a PV array was simulated being connected up to the power converters. The transient change of the output current of PV array under the real field weather condition was described and also the output current of the DC/AC converter flowing to the utility power network was analyzed with the PWM switching width. Moreover, the MPPT control of the PV power generation system was combined to the system on simulation. The outcome of the simulation demonstrates the effectiveness of the proposed simulation scheme. The result shows that the cost effectiveness verifying for the efficiency or availability and stability of PV generation systems and the comparison research of various control schemes like MPPT under the same weather conditions are possible.
