Frequency Control of Single Area Hybrid Power System with DG

Analysis of power output vs load profile in a system with scattered generation resources connected to the existing traditional energy system is critical, because even a minor frequency shift might cause a total blackout. The load frequency management problem for a hybrid coal-based system incorporated with DG, consisting of fuel cells, diesel engine generators, wind turbine generators, aqua-electrolyzer, and battery energy storage system is explored in this work. Due to the significant output power variation of wind energy systems, integrating them into DG offers a challenge for the creation of an appropriate controller. The stochastic volatility of the load profile makes this issue more difficult. The study’s suggested control method relies on differential evolution (DE). For various disturbances, the efficiency of frequency stabilization is studied. The results demonstrate how the hybrid DG system’s PID controller was able to achieve the least amount of frequency variation.
