Robust power control design for wind energy in microgrid

Abstract

There has been extensive research concerning wind turbine power generators. However, reducing wind turbine uncertainty in a microgrid with gas turbine and storage has received limited interest. Our objective is to reduce costs, while controlling a microgrid in an environment friendly manner. Since the production and consumption of wind energy is unpredictable, it is desirable for the connection between a wind farm and a gas turbine to maintain a constant energy output for the consumer. This dissertation presents an optimal control design strategy for a microgrid system that delivers electricity from wind and gas turbines through joint control centers. These control centers are able to utilize any extra green power by introducing an energy storage facility. Simulation results have shown an improvement in power availability to the consumers with both consumption and production uncertainty.
