本研究提出了一个100%逆变器传输系统的控制和功率共享设计和架构。这样的操作场景已经在美国、欧洲和澳大利亚的几个系统的部分地区发生了很短的时间，并且将来可能会更频繁。该算法使基于逆变器的资源（IBR）能够参与基于角下垂方法的电力共享，该方法明确考虑了IBR额定值和首选设定点。这种策略的结果是电力系统本质上的恒频运行，而不依赖于二次控制器或通信进行频率恢复。通过在PSCAD/EMTDC软件中进行广泛的仿真案例研究，评估了所提出的架构在不同操作条件下的性能。
This study proposes controls and power sharing design and architecture for a 100% inverter‐based transmission system. Such an operation scenario has already occurred for short periods in portions of several systems in the United States, Europe, and Australia, and is likely to be more frequent in the future. The proposed algorithm enables the inverter‐based resources (IBR) to participate in power sharing based on an angle droop method that explicitly takes into account the IBR ratings and preferred set points. This strategy results in an essentially constant‐frequency operation of the power system without relying on secondary controllers or communication for frequency restoration. The performance of the proposed architecture under different operating conditions is evaluated via extensive simulation case studies in PSCAD/EMTDC software.
