Design of Parallel 2-DOF PID Controller by Bee Algorithm for Interconnected Thermal Power Systems

The article presents the design and analysis of the control of two connected thermal power generator systems by the parallel 2-degree freedom of proportional-integral-derivative (2-DOF-PID) and modified by the bee algorithm (BA). In general, power and control systems are generally characterized as non-linear, so the automatic gain controllers (AGCs) will need to be optimized for parameters, particularly the 2-DOF-PID controllers that use a large number of parameters. The bee algorithms and differential evolution (DE) have been presented to improve parameterization and compare the performance of such an algorithm while using a dynamic electric load size change approach. As a result of testing, when the bee algorithm is used to improve the parameters of the generator system, the system will be more robust to changes and have higher performance.
