Performance Assessment of Novel Solar Thermal-Based Dual Hybrid Microgrid System Using CBOA Optimized Cascaded PI-TID Controller

Abstract

The article assesses the frequency control of a dual area hybrid microgrid (DHM) that comprises solar thermal systems alongside biodiesel-powered generators, energy storage components, and DC link. The chaotic butterfly optimization (CBOA) technique is used to attain the tuned gain constraints of the cascaded PI-TID controller. The novelty of the system lies in the integration of a combined solar gas turbine and solar chimney for load frequency control studies. Also, the application of CBOA to tune the controllers of cascaded PI-TID controllers is a novel approach. The superiority of CBOA tuned PI-TID controller is obtained after performing a comparative analysis of PID, TID, and PI-TID for controller selection and PSO, SCA, BOA, and CBOA for selecting the superior algorithm. The outcome of each component of the system is analyzed and subjected to the consideration of different real-time scenarios. Sensitivity evaluation is carried out by altering the source and load settings to establish the domination of the CBOA optimized PI-TID controller.
