Voltage and Frequency Droop Control in Low Voltage Grids by Distributed Generators with Inverter Front-end
In recent years, an ongoing increase of grid-connected distributed and renewable electricity generation technologies is clearly noticeable. From an environmental perspective, the increase of renewable technologies is highly desirable, as they do not emit greenhouse gasses and thus not contribute to climate change. Nevertheless, their increase poses increasing challenges on the reliable operatio...
متن کاملDC Voltage Control and Power-Sharing of Multi-Terminal DC Grids Based on Optimal DC Power Flow and Flexible Voltage Droop Strategy
This paper develops an effective control framework for DC voltage control and power-sharing of multi-terminal DC (MTDC) grids based on an optimal power flow (OPF) procedure and the voltage-droop control. In the proposed approach, an OPF algorithm is executed at the secondary level to find optimal reference of DC voltages and active powers of all voltage-regulating converters. Then, the voltage ...
متن کاملA New Control Strategy for Voltage Restoration and Voltage Unbalance Compensation in an Islanded Droop-Controlled Microgrid
Low voltage microgrids including sensitive loads often face unbalanced load conditions. Therefore, a compensation procedure should be carried out in order to balance and restore sensitive load’s voltage. In this paper, an effective voltage control strategy has been proposed for the autonomous operation of microgrids, under unbalanced load conditions. The proposed strategy balances single-phase...
متن کاملOptimal Droop Control for Voltage Source Converters in Islanded Microgrids
A new procedure for the design of the droop control for voltage source converters (VSC) in islanded microgrid is presented. The droop control is commonly used to achieve the power balance in power system. It consists in a simple proportional control and the selection of its gains are commonly based only on power balance criteria. However, some values of the gains may cause poor damped responses...
متن کاملVoltage 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...
