Over the past few years, modular multilevel converters (MMCs) have become increasingly widely used in the transmission and distribution of electrical systems. Nevertheless, the problem of spreading current inside the converter's circuit has been a topic of worry, resulting in greater loss of conduction in switches & increased thermal strain on capacitors & IGBTs. Maintaining a balanced voltage at the capacitors in the MMC is a critical tactic in addressing this problem. For the transmitted modular multilevel converter, a novel hybrid control approach is presented in this study. It utilises the Grey Wolf's Optimisation (GWO) & Cuckoo Search Algorithms (CSA) to produce optimum controller design. The modular multilevel inverter construction that has been suggested ensures excellent performance, low distortion in the final voltage, a decreased switching frequency, and exceptional flexibility to meet various voltage level requirements. The efficiency of the suggested controller with multilevel converter is validated by comprehensive testing, notably in the context of the MMC-Static Asynchronous Compensator (also known as ST application. Under the combination of balanced and unbalanced circumstances in the network under study, the stability of capacitance voltages is closely inspected. In comparison to the original HHO and ASO techniques, the findings demonstrate the remarkable efficacy of the GWO as well as CSA-based hybrids controller algorithm. This demonstrates how it may raise the system's general effectiveness and stability.
