Voltage regulation, network balancing, and stability enhancement are just few of the many uses for static synchronous compensators in alternating current electrical networks. These compensators, which boost the performance of ac networks by smoothing out voltage fluctuations, have been the subject of extensive study. In this paper, we provide a complete method of control for synchronous compensators operating in deviant network environments. This control method is novel because it incorporates both a novel reactive current reference generator and a novel voltage support control loop. The present reference generator's standout characteristic is its precision in producing reactive current, even when the voltage amplitude drops as in a voltage sag. The system's reliability is ensured by setting the minimum current demand at the maximum rated current. By altering the two voltage set points, the voltage control loop can implement a wide variety of control systems. This study presents three different voltage support control systems and compares and contrasts their features and shortcomings. Two theoretical contributions made in this investigation have been verified by experimental evidence. Clearly, there is a need for more research on the topic of voltage support, and the control system demonstrated in this dissertation can be seen as an intriguing arrangement for the development of different control systems in future investigations.
