The current mainstream technical approach is to have CIGs emulate the operational characteristics of SGs and to follow the traditional active power-frequency control framework. This approach not only inherits various stability issues of the system dominated by SGs, but also introduces some new converter-driven stability problems, and has compromised the system's safety and hindered the development of renewable energy sources. Here we propose a novel frequency-fixed active power control (FF-APC) framework that maintains active power balance independently of frequency for the system dominated by CIGs. In this framework, the system frequency is almost always fixed at its rated value, and power flow adjustments are implemented through direct phase angle control. The approach eliminates various safety issues related to frequency variations, and significantly enhances the ability to maintain synchronization and prevent oscillations. Moreover, it is compatible with existing power sources and therefore can be gradually implemented in current power systems. Our work breaks through the frequency-based power control framework that has been in use in AC power systems for over a century, and is more suitable for integration of renewable energy sources.
