Selection of linear feedback to operate with plants having actuator saturation limits has long been important in control design research, with one approach represented in the work of Saberi and his co-workers. The work here seeks to tailor this “saturation-accommodating” design method to problems motivated by integrating into the grid renewable energy sources, such as wind turbines, and energy storage...
The paper addresses a novel scheme for the control of variable wind energy and energy storage plant such that the generation and energy storage can deliver a smooth and constant power as demanded by the grid load. In addition, the wind energy generators are assumed large compared to the local grid rating and will contribute to the voltage and frequency regulation of a grid using adaptive frequency...
Grid integration of wind power plants is complicated by wind variability and the technical characteristics of wind generators. At high levels of wind power penetration, the need for several types of ancillary services increases while the traditional resources that provide those services may become less economic or available. This paper describes a suite of advanced wind plant controllers designed...
Rising wind generation penetrations and the distinctive inertial characteristics of associated turbine technology will impact system frequency control. While wind production will displace conventional synchronous plant, empirical study data presented also suggest that the relationship between the total stored turbine kinetic energy and the total system power production for wind is a variable that...
The increasing penetration rate of wind generation in power system is likely to change frequency behavior of grid. This is due to the specific response of these technologies to frequency changes. In order to better assess these changes, this paper focuses on the primary frequency control requirements. It now appears that an active contribution of wind power will be required to cope with high level...
