Intelligent Robust Direct Power Controller for Grid Connected Voltage Level Multiplier Module Inverters

The voltage level multiplier module is an emerging class of compact power electronic topologies that aims to maximize the power quality and conversion efficiency using minimum active and passive components. The promising merits of voltage-level multiplier module inverters (VLMMI) render them ideal for integrating renewable energy into microgrid environments. This paper presents a new intelligent direct power control (IDPC) technique for grid-connected VLMMIs to control the power flow directly through a distributed energy resource management system (DERMS). Furthermore, a robust control algorithm is developed using sliding mode control theory to regulate and stabilize the voltage and current of the VLMMI in the grid-connected mode of operation. Preliminary simulation results confirm that the proposed IDPC supported by the robust controller allows VLMMIs to effectively operate in microgrids and accurately respond to a DERMS.
