Model Predictive Control for Hybrid AC/DC Micro-grids

This paper introduces a smart model predictive control system for hybrid micro-grids which are utilized for voltage regulate and controlling in transient mode operation of hybrid AC/DC micro-grid. Various voltage control approaches have been successfully achieved within AC and DC grids, but the control of hybrid micro-grid depends upon more consideration with spotlight on inter-linking converter (ILC). Model predictive control (MPC) is applied to a hybrid micro-grid, which consists of DC and AC sources. The DC sources include photovoltaic farm, vehicle to grid, while the AC sources are Diesel farm and wind farm. They are connected to the main power grid. The power system is simulated utilizing Simulink/MATLAB. The system is operated at different loading and generation condition to determine the variation of voltage against power variation. MPC unit is added in different locations and scenarios. It is effective in controlling the main bus voltage and frequency. By testing the MPC on the simulated tested system the results are satisfied.
