Background:
Due to the increasing demand for the electrical power and limitations of
conventional energy to produce electricity.
Methods:
Now the Microgrid (MG) system based on alternative energy sources are used to provide
electrical energy to fulfill the increasing demand. The power system frequency deviates from its nominal
value when the generation differs the load demand. The paper presents, Load Frequency Control
(LFC) of a hybrid power structure consisting of a reheat turbine thermal unit, hydropower generation
unit and Distributed Generation (DG) resources.
Results:
The execution of the proposed fractional order Fuzzy proportional-integral-derivative (FO
Fuzzy PID) controller is explored by comparing the results with different types of controllers such as
PID, fractional order PID (FOPID) and Fuzzy PID controllers. The controller parameters are optimized
with a novel application of Grasshopper Optimization Algorithm (GOA). The robustness of the
proposed FO Fuzzy PID controller towards different loading, Step Load Perturbations (SLP) and random
step change of wind power is tested. Further, the study is extended to an AC microgrid integrated
three region thermal power systems.
Conclusion:
The performed time domain simulations results demonstrate the effectiveness of the
proposed FO Fuzzy PID controller and show that it has better performance than that of PID, FOPID
and Fuzzy PID controllers. The suggested approach is reached out to the more practical multi-region
power system. Thus, the worthiness and adequacy of the proposed technique are verified effectively.
