Global control of complex power systems

This chapter presents an overview of recent results on an approach to total control of power systems. It is upwards compatible from any conventional or prior advanced control and provides a framework for coordinated development of control to address all major dynamical problems. The approach appears applicable to complex systems generally where behaviour is influenced by nonlinearity, large-scale, uncertainty and hybrid nature. In particular, the presence of bifurcations of various kinds is allowed for while using ideas from switching and optimal control. The approach will be illustrated by consideration of coordinated control for transient stability, voltage regulation and emergency voltage control of power systems
