VS-CCI and VS-CCI/APF configuration for PMSG wind energy conversion system

Recently, many efforts are dedicated to finding the most efficient way to utilise wind energy as a power source and integrate it to the grid. This paper presents a permanent magnet synchronous generator (PMSG) wind energy conversion system (WECS) with reactive power control. The WECS is implemented through a voltage source - current controlled inverter (VS-CCI). The implementation of WECS with reactive power control allows the system not only to supply renewable active power to the grid, but also reactive power to maintain the grid power factor at unity. The VS-CCI is capable of providing reactive power support and requires no additional components. A comparison of the reactive power configuration of the VS-CCI and the active power filter (VS-CCI/APF) configuration is also presented in this paper.
