Abstract

To ensure that customers receive a steady and dependable supply of electricity, power systems must operate and be under control. One of the main problems encountered during interruptions to the system is irregular electrical power flow through interconnected power areas and frequency aberrations. Therefore, the load frequency control system (LFC) was used to reduce frequency variations and provide a stable power flow in multiple-areas power system. This study presents several techniques for controlling the load frequency in two area power systems employing a combination of fractional order proportional integral derivative (FOPID) and fuzzy logic-proportional integral derivative (FPID) controllers and comparing them to conventional controllers (PID). MATLAB/Simulink is used to simulate the overall system. The error is estimated using the integral of time-weighted squared error (ITSE) goal function. In this paper, the settings of the suggested FOPID controller were adjusted using the zebra optimization algorithm (ZOA). Moreover, the settings of the traditional PID controller were modified using a fuzzy logic controller. To evaluate the effectiveness of the controllers and their superiority in handling disturbances, compared each of the controllers using the following three factors: overshoot, settling time, and peak time. The simulation's conclusions indicate unequivocally that the FOPID-ZOA controller works better than the fuzzy-PID and PID-ZOA controllers. Research has improved the quality of the ZOA-based controller FOPID, which is a very successful method for controlling load frequency in two-Area power systems. In the end, customers gain from this distinct solution's substantial contribution to power distribution stability, which guarantees a steady supply of electrical power even in the event of network troubles.
