With the integration of more distributed or aggregated renewables, and the wide utilization of power electronic devices, modern power systems are facing new stability and security challenges, such as the weakly damped oscillation caused by wind farms connected through long distance transmission lines, the frequency stability problem induced by the reduction of inertia and the voltage stability issue resulting from the interactions between transmission systems and dynamic loads. Meanwhile, synchronized phasor measurement technology developed very fast in the last decade, and more phasor measurement units (PMUs) and wide area measurement systems (WAMSs) have been deployed. These provide more insights into the system dynamics and approaches to overcoming the new challenges. This book addresses the emerging concepts, methodologies and applications of wide area monitoring, control and protection in power systems with integrated large scale renewables. Chapters cover monitoring, modelling and validation, control, and data mining with an emphasis on synchrophasor technology, and experiences with real power grids.

Focuses on the array beamforming technology that has been applied in current commercial communication system, including 5G communication, WiFi 6, etc, and has broad application prospects in future communication systems. Covers the basic principles of array signal processing and new technical problems in communication systems, including channel estimation, codebook design, point-to-point transmission, multiple access, networking, etc. Provides feasible solutions for these classical problems and heuristic guidance for further research in this field.
