This book illuminates how synchrophasors achieve the monitoring, protection and control optimizations necessary to expand existing power systems to support increasing amounts of renewable and distributed energy resources. The authors describe synchrophasor techniques that can provide operators with better resolution in capturing dynamic behavior of the power grid. The resulting insights support improved real-time decision making in the face of more generation and load uncertainty, as well as interruptions caused by random acts of nature and malicious attacks. Armed with the information in this cutting-edge resource, grid planners and operators can make optimized, flexible, resilient power systems a reality.

The use of advanced technologies has made it possible to transform the power grid to an intelligent smart grid with real time control and monitoring of the system. The development of Phasor Measurement Units (PMUs) and the resulting possibility of real time measurements has enabled different power system applications to enhance the stability, state estimation, load estimation, power network protection, Wide-Area Security Assessment and reliability of the power grid.

Classic power system dynamics text now with phasor measurement and simulation toolbox This new edition addresses the needs of dynamic modeling and simulation relevant to power system planning, design, and operation, including a systematic derivation of synchronous machine dynamic models together with speed and voltage control subsystems. Reduced-order modeling based on integral manifolds is used as a firm basis for understanding the derivations and limitations of lower-order dynamic models. Following these developments, multi-machine model interconnected through the transmission network is formulated and simulated using numerical simulation methods. Energy function methods are discussed for direct evaluation of stability. Small-signal analysis is used for determining the electromechanical modes and mode-shapes, and for power system stabilizer design. Time-synchronized high-sampling-rate phasor measurement units (PMUs) to monitor power system disturbances have been implemented throughout North America and many other countries. In this second edition, new chapters on synchrophasor measurement and using the Power System Toolbox for dynamic simulation have been added. These new materials will reinforce power system dynamic aspects treated more analytically in the earlier chapters. Key features: Systematic derivation of synchronous machine dynamic models and simplification. Energy function methods with an emphasis on the potential energy boundary surface and the controlling unstable equilibrium point approaches. Phasor computation and synchrophasor data applications. Book companion website for instructors featuring solutions and PowerPoint files. Website for students featuring MATLABTM files. Power System Dynamics and Stability, 2nd Edition, with Synchrophasor Measurement and Power System Toolbox combines theoretical as well as practical information for use as a text for formal instruction or for reference by working engineers.

Recent growth in deployment of distributed energy resources (DERs), energy storage systems, and advanced grid control schemes have increased the levels of variability in generation and load conditions over the electric transmission and distribution system. Microgrids are distribution level power systems that operate as a single controllable system in a grid connected or islanded (disconnected) mode. The balance between supply and demand of power is one of the most important requirements of microgrid management. The ability to control such a system hence becomes a very important task in order to stably and smoothly operate the microgrid. One such elegant method to overcome these challenges is the use of the phasor measurement units (PMUs) for wide-area distributed networks capable of measuring time-synchronized phasor (synchrophasor) data at high rates in the multiples of the main AC frequency (up to 240 Hz for a 60 Hz signal). The importance to use synchrophasors for this application is two-fold: Firstly, the ability for high frequency and synchronized sampling significantly enhances (transient) grid monitoring and also improves performance of the state estimation or (recursive) prediction that can be used for real-time control. Secondly, synchrophasor measurements can be used to coordinate the power exchange between cooperative multiple loads (microgrids) using the time-synchronized measurements. However, due to the high sampling rates of synchrophasor data, it becomes an unwieldy task to process such huge data from multiple locations. Local (signal) processing of PMU data to detect, store and classify events in the electric grid at the point of measurement is one of the main contributions of the dissertation. To address the demand and supply problem in a microgrid, (recursive) demand prediction and (optimal) generation dispatch techniques using synchrophasors are discussed in the dissertation. In order to design high speed control algorithms for such microgrid systems, derivation of a system model via system identification using data driven techniques would be more convenient than derivation via swing equations. Hence, the dissertation contributes in the estimation of a low order linear time invariant (LTI) model for active and reactive power flow (derived from the PMUs) through the microgrid. Using the derived models, it is shown how real-time PMU measurements can further be used in the islanding (power flow and angle) control of microgrids. Finally, robustness of missing PMU data for control applications is addressed in the dissertation.
