Novel Model Predictive Current Controller for Grid Connected Inverters in a Smart-Grid Environment

This paper proposes a novel current controller for grid connected inverter. It is a new variant of non-linear Model Predictive Controller (MPC) which is modified from the available MPCs widely applied in chemical process systems. This proposed MPC is developed such that to adapt for fast response systems such as micro-grid and smart-grid systems. Using Matlab/Simulink a micro-grid system model with one inverter and local loads connected to grid is developed to study the new MPC along with already available Proportional Integral controller and hysteresis controller.
