This work presents the design and analysis of an optimized Proportional-Integral-Derivative (PID) controller for photovoltaic (PV)-based microgrids integrated into power systems. . Microgrids are a part of the power system that consists of one or more units of distributed generation and are expected to remain in operation after being disconnected from the system. Since they rely on overlying networks, frequency control is very important for network-independent operation. Some. . Microgrids (MGs) are installed with renewable energy sources (RES) to meet the dynamic load demands. Conventional PI controllers often suffer from issues such as prolonged oscillation time, high amplitude responses. . This study provides a novel methodology to design an A. off-grid multi-microgrid (MMG) system and suggests an analytical method for load frequency management utilizing a multistage PID (MPID) controller based on the sine cosine algorithm. The unique benefits of an MMG system are similar to those. .
