Optimization of voltage control in wind farms

Abstract

In recent years, wind power has experienced a wide development, emerging both as a potentially attractive means of providing new electricity generating capacity. In addition, modern wind power generators use double fed induction technology that makes the control the reactive power possible. These technology developments allow wind farms to adjust reactive power interchange with the network to the power factor requirements established by the DSO. This paper presents an OPF for power losses minimization of a wind farm using reactive power of wind power generators as control variables. The OPF also considers power factor requirements established by the DSO. Performance of the method proposed is illustrated considering actual load scenarios of a wind farm.
