Hybrid Control Design for Improvising the Performance of Multi-tap Variable Shunt Reactors

Nowadays, there is a scarcity between the demand and supply of electrical energy, this is because of the instability of high voltage transmission and the reactive load used at consumer's side. This is one of the biggest issues so far in transmission lines. Researchers prefer the utilization of shunt reactors to reduce this instability issue. These conventional shunt reactors work like an ordinary electro-mechanical relay and therefore have sluggish switching response. This paper proposes the use of thyristors-based multi-tap shunt reactors that are fully controlled using an intelligent Fuzzy based Proportional Integral Derivative (F-PID) control algorithm. This proposed strategy will initiate a voltage rise at receiver end to stabilize the system and reduces the settling time. The paper comprises of simulation results that are performed on MATLAB R2020a version and later validated with hardware design based on Arduino Mega controller.
