Implementation of an 11-Level Inverter with FACTS Capability for Wind Energy Systems

Abstract

In this paper, a new single-phase wind energy inverter (WEI) with flexible AC transmission system (FACTS) capability is presented. The proposed inverter is placed between the wind turbine and the grid, same as a regular WEI, and is able to regulate active and reactive power transferred to the grid. This inverter is equipped with distribution static synchronous compensators option in order to control the power factor (PF) of the local feeder lines. The goal of this paper is to introduce new ways to increase the penetration of renewable energy systems into the distribution systems.
