Moreover, the fast growth of wind energy poses the increasing need for high-power, low-loss, and fast-switching power electronic devices in order to reduce the system complexity and cost, and improve reliability and compactness. Among the

In this chapter, an operating policy is proposed for hybrid wind-hydro power stations (HPS) in island grids, in order to increase wind penetration levels, while at the same ti
