Abstract
The paper confers an extensive assessment of the load frequency control (LFC) technique, effectively utilized for frequency regulation in the power system. The scope of LFC is to restore the mismatch between the load and generation in each control area and minimize the transient deviations with zero steady-state error in advance. This paper addresses the structural design, methods, and methodologies carried out in conventional, deregulated and microgrid systems used widely to suppress the frequency deviations occurring in the power sector for various reasons. It enumerates the recent trends and approaches in designing different market models and proposes control strategies for structures integrated with renewables and flexible AC transmission systems (FACTS) devices. This critical research also imposes the need for frequency regulation for the microgrid systems that include distributed energy resources and related findings.
