Statistical voltage quality evaluation of wind farm-connected grid network

Reactive power optimisation considering wind farms based on an optimal scenario method

“…Reactive power optimisation (RPO) is used to plan the best voltage profile of a grid in the presence of a series of physical and operating constraints, so as to produce the least real power losses or improve the voltage equality [1–3]. As growing numbers of wind generators are invested in grids, their uncertainty leads to frequent voltage fluctuation due to system reaction delay [4]. This results in voltage quality problems such as voltage beyond limits, increasing power losses and the production of inferior products.…”
