Modelling and Stability of Smart Grids

This comprehensive book describes how to systematically assess the stability of electrical grids with a high share of power electronics converters and considers what their presence in the electrical grid entails. It is divided into three areas: Part 1 presents the three fundamental stability analysis methods and tools for power electronics systems; Part 2 examines applications in power utility systems; and Part 3 describes applications in microgrids and mobile power systems. Topics covered include linear state-space phasor methods; impedance analysis in synchronous reference frame; effects of distortion on stability; harmonic linearisation and sequence impedance analysis; nonlinear effects of power electronics on stability; grid-connected inverters for renewable energy and energy storage; high voltage dc transmission converters and systems; power electronics controllers in power systems; stability impact of grid impedance and interactions with grid synchronisation methods; droop controllers in microgrids; internal protections and limitations of converter control systems and their impact on stability; agent-based control of microgrids; adaptive control of microgrids; electric ship power systems. Modelling and Stability of Smart Grids will be invaluable to researchers and advanced students in power electronics and power grid engineering.
