Power System Simulation Using Semi-Analytical Methods

"The purpose of this book is to enhance the speed of time-domain simulations of bulk power systems by introducing a semi-analytical methodology that integrates various simulation techniques. This new approach differs from traditional simulations that use low-order numerical integrators. Instead, it employs a high-order analytical form that approximates the dynamic response of the system with improved accuracy. By embedding symbolic variables and parameters, the resulting semi-analytical solution allows for the decomposition ... Read More

"The purpose of this book is to enhance the speed of time-domain simulations of bulk power systems by introducing a semi-analytical methodology that integrates various simulation techniques. This new approach differs from traditional simulations that use low-order numerical integrators. Instead, it employs a high-order analytical form that approximates the dynamic response of the system with improved accuracy. By embedding symbolic variables and parameters, the resulting semi-analytical solution allows for the decomposition of its computation into sequential or concurrent processes, reducing the time required for simulations. Additionally, a significant amount of computation can be performed offline before a simulation run is needed or be parallelized, making the simulations even faster. These semi-analytical methods can be integrated or interfaced with existing numerical integrators to create more robust power system simulators that can be used with high-performance parallel computers. The book is structured to provide a comprehensive and systematic coverage of such emerging methods for finding semi-analytical solutions and accelerating power system simulation, as documented in literature"-- Read Less
