Predictive discrete‐time sliding mode based direct power control for grid‐connected energy conversion systems

A method for digital direct power control design grid-connected energy conversion systems was proposed in this paper. The active and reactive powers are directly controlled with constant switching frequency by selecting an appropriate sequence of voltage source converter as a key part systems. combines discrete-time sliding mode predictive control. selection feasible vectors is result the approach. These satisfy existence conditions mode, but each them induces system motion different properties. task to select reduce chattering phenomenon, steady-state error, overshoot. cost function prediction process defined average value both errors on horizon three sampling periods. Simulation results, experimental results comparative analysis presented order show performance effectiveness design.
