A Closer Look at the CPU and GPU Architecture

From the perspective of architecture, both the multi-core CPU and many-core GPU package several cores into one die, sharing the same memory channel. To maintain high performance, this type of computation architecture needs to have a high-speed memory bandwidth, feeding data to and getting results from computa­tional cores. Generally, the performance of the computation architecture […]

Maintaining adequate dynamic voltage support (reactive power ca­pability) to respond to voltage events

Generation resources utilizing traditional synchronous generation technology employ a standard Automatic Voltage Regulator (AVR) to ensure automatic vol­tage control. In the case of wind units, while the older wind units rely on external switching devices (capacitor banks, Static Var Compensator (SVC) etc) for reac­tive power support the newer wind units utilize the in-built power electronic […]

Features of the Numerical Methods Applied to Power System Calculations

To identify the features of performance issue in power system calculations, this work evaluates the serial version of the conjugate gradient normal residual (CGNR) [44] in the context of the power system state estimation application. The CGNR method is selected because it is a general technique for solving a WLS based system of linear equations […]
