Abstract—This paper proposes a novel control for Inverter-based Resources (IBRs) based on the Complex Frequency (CF) concept. The controller's objective is to maintain a constant CF of the voltage at the terminals of the IBR by adjusting its current reference. Utilities must maintain reliability on the distribution grid and are. . These systems often require the capability to operate either connected to the main grid or in islanded mode where inverters also help control voltage, frequency, and power flow, ensuring stable and efficient integration of renewable energy into the grid.

The methodology integrates controlled energy storage systems, including ultra-capacitors (UC), superconducting magnetic energy storage (SMES), and battery storage, alongside a robust frequency regulation management system (FRMS). . The rapid proliferation of renewable energy sources (RESs) has significantly reduced system inertia, thereby intensifying stability challenges in modern power grids. To address these issues, this study proposes a comprehensive approach to improve the grid stability concerning RESs and load. . One of the critical aspects of grid stability is frequency regulation, which involves maintaining the grid frequency within a narrow range to ensure reliable operation of the power system. It involves balancing electricity supply and demand to ensure that the frequency of alternating current (AC) remains within a specified range—typically 50 or 60 Hz, depending on the region.
