Voltage Imbalance Compensation for Droop-Controlled Inverters in Islanded Microgrid
In this paper, a new control strategy is proposed for implementation in low-voltage microgrids with balanced/ unbalanced load circumstances. The proposed scheme contains, the power droop controllers, inner voltage and current loops, the virtual impedance loop, the voltage imbalance compensation. The proposed strategy balances the voltage of the single-phase critical loads by compensating the im...
متن کاملAdaptive Sliding Mode Control of Multi-DG, Multi-Bus Grid-Connected Microgrid
This paper proposes a new adaptive controller for the robust control of a grid-connected multi-DG microgrid (MG) with the main aim of output active power and reactive power regulation as well as busbar voltage regulation of DGs. In addition, this paper proposes a simple systematic method for the dynamic analysis including the shunt and series faults that are assumed to occur in the MG. The pres...
متن کاملRobust Event-Triggered Output Feedback Learning Algorithm for Unknown Voltage Source Inverters
We consider the output feedback event-triggered control of an off-grid voltage source inverter (VSI) with unknown L ́ C filter dynamics and connected load in the presence of an input disturbance acting at the plant. Due to uncertain dynamics and unmodelled parameters in the L ́ C filter connected to the VSI, we use an adaptive observer to reconstruct the system’s states. The control mechanism is...
متن کاملPerformance Improvement of Single-Phase Transformerless Grid-Connected PV Inverters Regarding Common-Mode Voltage (CMV) and LVRT
The single-phase transformerless grid-connected photovoltaic (PV) systems, mainly the low-power single-phase systems, require high efficiency, small size, lightweight, and low-cost grid-connected inverters. However, problems such as leakage current, the DC current injection and safety issues are incorporated with transformerless grid-connected PV inverters. Besides, the new standards such as Lo...
متن کاملVoltage Unbalance and Harmonics Compensation for Islanded Microgrid Inverters
Voltage source inverters (VSIs) are usually used for all kinds of distributed generation interfaces in a microgrid. It’s the microgrid’s superiority to power the local loads continuously when the utility fails. When in islanded mode the voltage and frequency of the microgrid are determined by the VSIs, therefore the power quality can be deteriorated under unbalanced and nonlinear loads. A volta...
