PV solar farms operate only during the day and are completely idle in the nights. This research program proposes a novel utilization of the PV solar farm inverters in the nighttime as STATCOM - a Flexible AC Transmission System (FACTS) Device. This novel control allows the solar farm inverter to be used in the night for accomplishing a variety of power system objectives, such as improving system stability, and power transmission capability in transmission systems as well as for performing load compensation in distribution systems. During the day also, the above objectives can be achieved to a substantial extent through the inverter capacity left after production of real power. Similar STATCOM control functionality can also be implemented in inverter based wind turbine generators during no-wind or partial wind scenarios for improving the transient stability of the power system and for other objectives. Since PV solar farms operate during the days and wind farms typically produce peak power in the nights, such novel controls of the solar farm and inverter based wind farm can complement each other and facilitate increased grid connectivity of both the renewable generation systems.

光伏太阳能发电场只在白天运行，晚上完全闲置。本研究计划提出了一种新的利用光伏太阳能发电场逆变器在夜间作为STATCOM -灵活的交流输电系统（FACTS）设备。这种新颖的控制允许太阳能发电场逆变器在夜间使用，以实现各种电力系统目标，例如提高系统稳定性和传输系统中的电力传输能力，以及在配电系统中进行负载补偿。同样在白天，上述目标可以通过在产生真实的功率之后剩余的逆变器容量在很大程度上实现。类似的STATCOM控制功能也可以在无风或部分风的情况下在基于逆变器的风力涡轮机发电机中实现，以提高电力系统的瞬态稳定性和用于其他目的。由于PV太阳能发电场在白天运行，而风力发电场通常在夜间产生峰值功率，因此太阳能发电场和基于逆变器的风力发电场的这种新颖控制可以相互补充，并促进两个可再生发电系统的电网连接性的增加。
