Low-voltage ride-through (LVRT) requirements demand wind-power plants to remain connected to the network in presence of grid-voltage dips. Most dips present positive-, negative-, and zero-sequence components. Hence, regulators based on symmetrical components are well suited to control grid-connected converters. A neutral-point-clamped topology has been considered as an active front end of a distributed...
In this paper, a new control strategy based on current mode control for dynamic voltage restorer (DVR) is proposed to mitigate the power quality problems in the supply voltage. The DVR is controlled indirectly by controlling the supply current. The reference supply currents are estimated using the sensed load terminal voltages and the dc bus voltage of DVR. The control scheme is based on synchronous...
The paper discusses a bidirectional DC/DC converter for interfacing an energy storage device in an autonomous power system, which consists of wind turbines and diesel generation units. The operation condition variations, such as switching load, could cause significant dynamics in an autonomous system. An energy storage device can effectively increase the utilization of the renewable energy and improve...
