Smart loads are now a days immensely used in isolated microgrid systems for various application. This technology contributes towards demand side management. This feature makes it a smart device in future energy crises. The smart load is the combination of an electric spring and some voltage insensitive loads. The electric spring in this work is considered to be a bidirectional voltage source converter. This paper focuses on improving the voltage profile of an isolated system. Bolstering the robustness and low-cost application by improvising the control structure can be the major research gaps in this particular field. In this work a novel control strategy for the operation of the smart load is suggested. The smart load performance with new control strategy is evaluated for both load and torque variation in real time simulation. The superiority of the control strategy is proved by comparing it with the traditional quadrature control scheme. The whole modelling and simulation are carried out on OPAL-RT 4510 platform.
