Wide area monitoring, protection and control systems (WAMPACs) have been recognized as the most promising enabling technologies to meet challenges of modern electric power transmission systems, where reliability, economics, environmental and other social objectives must be balanced to optimize the grid assets and satisfy growing electrical demand. To this aim WAMPAC requires precise phasor and frequency information, which are acquired by deploying multiple time-synchronized sensors, known as Phasor Measurement Units (PMUs), providing precise synchronized information about voltage and current phasors, frequency and rate-of-change-of-frequency. This book provides an overview of this emerging technology. Topics covered include an introduction to WAMPACs; reliability-based substation monitoring systems placement; system integrity protection scheme based on PMU technology; new methodologies for largescale power system dynamic analysis; a fuzzy-based knowledge discovery paradigm for on-line optimal power flow analysis; and false data injection attacks and countermeasures for wide area measurement system.

Commercial energy storage has moved from the margins to the mainstream as it fosters flexibility in our smarter, increasingly integrated energy systems. Natural gas has been identified by many as the fuel to take us to the no-carbon horizon; where a hydrogen economy waits on development. These two actors are already connected in precursor applications as transitional solutions for hydrogen handling and transportation are sought ahead of a fully established hydrogen infrastructure. This monograph explores some of leading advances in methane and hydrogen storage as well as the interesting link between these two important elements in our evolving energy system mosaic. Topics covered include: hydrogen absorption for storage; power-to-gas for energy system integration and storage; methanation for power-to-gas applications; production of hydrogen from methane decarbonisation into power to gas scenarios; power-to-gas in an ancillary service market; methane in MOFs: where, why and how; thermal management as a key in storing adsorbed natural gas; and gas hydrate potential and development for methane storage.
