The ever mounting demand of electrical energy and the keen scarcity of conventional energy sources leads to the burgeon of distributed generation (DG) system. The main abstruse is the harmonization of the DG to the utility grid. Generally current regulated PWM voltage-source inverters (VSI) are used for synchronizing the utility grid with DG source in order to meet the following objectives: 1) To...
In most of the situations, power electronics converters are mainly used as an interfacing device between distributed generation (DG) system and utility grid in order to meet the following objectives: 1) grid synchronization 2) active and reactive power control through voltage and frequency control 3) improvement of power quality (i.e. harmonic elimination) etc. But due to wide variation of the reactive...
This paper proposes a mathematical model and a voltage/frequency regulation strategy for an islanded, electronically-coupled, distributed resource (DR) unit. The DR unit can either represent a distributed storage (DS) unit or a dispatchable distributed generation (DG) unit. The proposed control strategy benefits from the power circuit configuration, dq-frame current-control scheme, and the phase-locked...
