However, some technologies come with negative factors that limit its market penetration. For wind power, the quality of the generated power limits its extensive use. The main concern for the quality of wind power installations is the fluctuation of voltage levels, which can be attributed to transient states where of the wind turbine generators are first connected to the grid, steady-state levels attributed to the inherent nature of injecting power to the grid, momentary disruptions due to wind gusts and general wind speed variations. This paper adopts the One Cycle Control (OCC) method in a series connection topology, which here acts as a Unified Voltage Quality Conditioner (UVQC), to deal with most of the problems identified above. The new OCC-UVQC has many advantages including no reference calculation resulting in great simplicity, fast transient response, high precision, and a constant switching frequency. The principle of the proposed UVQC is provided in detail. The performance of the voltage quality improvement to the wind turbine is verified to be excellent with the provided experimental waveforms.

Voltage sags/dips may originate both from the source side and the load side. Without proper regulation, utility customers connected to the same bus could be disturbed. This paper studies the load side voltage sags caused by the resistive load disturbance and the current source type disturbance. The one-cycle controlled unified power quality conditioner (OCC-UPQC) can effectively compensate both the load side and the source side voltage sags under the resistive load disturbance. When the current source type disturbance is experienced, the load side voltage shows more significant improvement than the source side. The OCC-UPQC features constant switching frequency, simple circuitry, fast transient response, high precision, and excellent stability. The compensation strategies for load side voltage sags are analyzed and verified to be effective by experiments
