ABSTRACT
The advent of microgrids and increased utilization of renewable energy sources (RESs) contributed to the uncertainty of power generation in hybrid power systems (HPSs), which necessitated stringent monitoring and control of grid conditions. The large power swings in RESs cause significant deviations in frequency that can disrupt the stability of the system in case timely control actions are not initiated. Therefore, frequency control is of prime importance and has been handled by different levels of controllers in power systems. Data acquisition plays a major role in frequency control of HPSs for performing real-time control. In this context, supervisory control and data acquisition (SCADA) systems and phasor measurement units (PMUs) are studied based on their dynamic performance in real-time data acquisition. Additionally, the role of PMUs in frequency stability has been reviewed and the challenges faced in enabling PMUs for frequency control of HPSs has been presented.
