By combining PF control with frequency monitoring and control, the power system can maintain both the power factor and grid frequency within desired ranges, ensuring efficient operation and stable power supply.
So, it's important to note that the specific implementation of PF control and frequency synchronization can vary depending on the power system's characteristics, control infrastructure, and regulatory requirements. The control strategies and devices employed may differ between utility-scale systems and microgrids, as well as in different regions and power systems.
For power system efficiency, stability and reliability, monitoring of frequency and power factor are very important. Induction motors are the mainly used drive in industrial load areas are the inductive loading, responsible for lowering the power factor and reducing the system efficiency with increased current, could be controlled with in the limit needed for system stability, by field excitation control or providing capacitance bank, though with modern solar system batteries backup and, on line measurement, protection and control the limit have changed near to unity from 0.8 lag, depending on smartness of engineers.
For active power demand , the load frequency control is very important , by monitoring the frequency with in the limit, though with increased mechanical loading the increased active current would reduced the frequency and the load demand (as Ns=120(f))/P), giving sufficient time for economical load shearing to alternators for better system efficiency ….
