Energy-based transient stabilization using facts in systems with wind power

This paper considers the problem of transient stability in networks with wind power. The effects of large and sudden wind changes are considered and their impact on system stability is analyzed. Next, a nonlinear control logic referred to as the energy-based nonlinear control is introduced as a possible means of stabilizing the system during such disturbances. It is shown how the proposed energy-based nonlinear control applied to Flexible AC Transmission Systems (FACTS) can attenuate disturbances and increase system resilience in response to large disturbances. Potential impact of such FACTS control on system stability is illustrated on a real-world example of Flores Island in Portugal.
