Distribution systems analysis employs a set of techniques that allow engineers to simulate, analyse, and optimise power distribution systems. Combined with automation, these techniques underpin the emerging concept of the 'smart grid', a digitally-enabled electrical supply grid that can monitor and respond to the behaviour of all its components in real time. Distribution System Analysis and Automation provides a comprehensive guide to these techniques, with coverage including smart grid for distribution systems; introduction to distribution automation; network and radial load flow analysis; determination of the optimal topology for power electric systems; voltage VAR control and capacitor application; power quality and harmonics in distribution systems; harmonic filter design; distribution system restoration; short circuit analysis; arc flash concepts; numerical relaying and feeder protection; communication and control centres; and distributed energy resources. The book is based on over 30 years of experience in the field of power systems and combines theoretical concepts with real-world applications and MATLAB exercises.
