Smart Automatic Generation Control

While the main objectives of Automatic Generation Control (AGC) remains unchanged, it becomes more challenging to operate AGC to achieve the desired generation control performance and overall system economics performance. There is a need to make AGC smarter so that it has the capability to handle the additional complexities introduced by the energy and ancillary service market environment, and the uncertainties introduced by the integration of renewable energy resources to the power grids, which are essentially intermittent in nature. This paper presents a unified optimal control framework where network security, system control performance, and system economics are all considered. Several key modules are presented and investigated within this unified framework. The impacts of renewable energy resources such as wind generation on AGC are studied.
