Hydropower is a mature and cost-competitive renewable energy source, contributing the bulk of global renewable electricity. Over the past decades, computer technology has led to significant possible improvements in monitoring, diagnostics, protection and control through retrofitting of large plants, and there is potential for additional large plants as well as for smaller installations.This book presents a systematic approach to mathematical modeling of different configurations of hydropower plants over four sections - modeling and simulation approaches; control of hydropower plants; operation and scheduling of hydropower plants, including pumped storage; and special features of small hydropower plants. The chapters address the fundamentals and the latest concepts, providing the most appropriate solutions for cost-effective and reliable operation, and include several real-world case studies of hydropower plants in operation.Modeling and Dynamic Behaviour of Hydropower Plants is essential reading for researchers involved with hydropower, as well as for advanced students in power engineering.

Electric vehicles (EVs) offer a cleaner mode of personal transportation and a new way to store energy, but also present challenges to the grid due to additional distributed storage and load. With rising numbers of EVs on the streets, problems can include voltage limits violation or line congestion, mainly at the distribution level. All those operating devices in the grid, from network operators/managers to EVs owners, need fast communication with low latency, high security and reliability. The book addresses EVs as a driving source for realizing smart grid operation. It provides chapters from multidisciplinary academic and industry communities related to EVs charging schemes and technologies, and its associated communication, networking and information architectures.This book for researchers and practitioners provides a basis for full integration of EVs into the grid through extensive use of ICT tools in: (i) transport as energy storage system (TES) modelling, simulation and optimisation processes; (ii) vehicle on-line optimal control, estimation and prediction; (iii) energy system strategic planning with renewables; and (iv) supporting services such as those related to smart grid via smart charging.

Phasor measurement units (PMUs) provide time synchronized measurements of phase angles of voltages or currents. These synchrophasors are used in electricity grids to support planning and operation. In the past decade, transmission network planners and grid operators have been using PMUs for monitoring applications. Improvements are still needed to realise the full potential of PMU data for more complex power systems with distributed renewables and increased loads. Challenges related to noise and higher frequency components from various dynamic behaviours of grid components, including electric vehicles, are prevalent.This book conveys the technology of PMUs and the application of synchrophasors to wide-area networks and interconnected grids. The chapters cover synchrophasor-based applications and technologies, including monitoring of power oscillation, wide area control and predictive protection, congestion management in transmission networks, synchrophasor-based fault location for multi-terminal transmission systems, system integrity protection, and application of synchrophasor technology to microgrids.This book is important reading for researchers and engineers in academia and industry, and grid operators involved with power systems and renewable energy generation, networks and communication.
