6.1 Introduction

This chapter presents the stabilization aspect of energy cyber-physical systems (CPSs). The focus is on wide-area monitoring and control of smart grids, which is enabled by remote signals communicated from the phasor measurement units (PMUs) to the control center through a phasor data concentrator (PDC). A global positioning system (GPS) provides timing pulse to correlate the sampled measurements and achieve precise time synchronization. The PDC synchronizes the measurements from all the PMUs with microsecond precision and, under normal condition, sends data once every cycle ...
