Study of flatness-based Automatic Generation Control Approach on an NPCC system model

The rapid integration of wind power has begun to impact overall power system control, and particularly frequency control. On the other hand, power system sensor and measurement technologies have shown great improvement during the last decade. These technologies could allow for greater use of advanced control techniques based on wide-area measurement signals to mitigate the challenges related to wind and similar renewable resources integration. In this work, it is proposed that the Automatic Generation Control (AGC) can be performed using local Phasor Measurement Units (PMUs), in two levels of trajectory generation and trajectory tracking, based on flat systems properties. The approach is implemented on NPCC system in presence of load changes and wind power variations.
