Abstract

This paper proposes a robust control approach for improving the power quality in three-phase standalone based micro-grids. The key developed idea is to increase the disturbance rejection ability of an Interconnection and Damping Assignment Passivity-Based Controller (IDA-PBC)by adding an integral action. Indeed, the classical IDA-PBC techniques suffer from their parametric dependency. Hence, the use of the proposed technique allows enhancing the load voltage quality either in nominal operating conditions or in presence of system uncertainties. The power system circuit is modeled as a Port-Controlled Hamiltonian (PCH)system. Then, the control design is detailed. The validity of the proposed control algorithm is verified using simulation studies, and its effectiveness is illustrated through a comparison analysis with a Proportional-Integral (PI)under various operating conditions.
