A high power emulation of a wind farm

Abstract

As more wind farms are connected to the grid, the variable nature of wind energy begins to influence grid stability. Energy storage could help smooth the variable nature of wind energy. Laboratory demonstration and exploration of the interaction between different energy storage devices and wind energy could help improve and encourage wind energy integration. To this end, a wind energy and energy storage project will be implemented in WESRF?s lab comprising of a zinc bromine battery, supercaps, hydropower, and wind energy. In this thesis, a scale model of the wind farm component of the project is modeled and experimentally tested. The wind farm is physically modeled by a 120kVA three-phase controllable voltage source and controlled in the synchronous reference frame.
