In this paper, controlling of a DC-DC bidirectional converter is investigated using model predictive control (MPC) technique. The converter is supposed to connect a battery bank to the DC bus. The main purpose of MPC method is to maintain the DC bus voltage in a predefined rated range, which means injecting active power to the DC bus to increase bus voltage and discharging the battery, and on the contrary absorbing active power from the DC bus to decrease bus voltage and charging the battery. The control strategy also disconnects the battery bank while DC bus voltage is in the predefined rated range. Simulations have been done in PSCAD/MATLAB software interfacing and results show the feasibility of the proposed controlling strategy to conduct active power on both directions.
