Power system applications for phasor measurement units

Identification of Dynamic Load Model Parameters Using Particle Swarm Optimization

“…In other words, it can be applied for load model parameter estimation in the long-term period. As one of current research trends, the researchers are very interested in on-line load modeling using the information from the rather fast monitoring devices such as PMU (phasor measurement units) [18]. For the purpose of on-line load modeling, a deterministic algorithm, one of steepest descent algorithms, needs to be combined with PSO into a kind of hybrid technique.…”

Power System Voltage Stability Classification Using Interior Point Method Based Support Vector Machine(IPMSVM)

“…where α i is the Lagrangian multiplier of the i-th inequality constraint in (1). Instead of the primal problem, the dual problem is usaully used for SVM solutions, because its applicability to nonlinear kernels is better.…”

“…Obviously, however, the SCADA/EMS system has a difficulty to capture dynamic responses after severe disturbances occur. To compensate for this difficulty, phasor measurement units (PMU) was devised and proposed in the power engineering field [1], which fulfills the requirement of real-time monitoring for the view of power system dynamic responses. Time series data from the fast measurement devices can provide the insight of system dynamics to the operators.…”

Genetic algorithms applied to phasor estimation and frequency tracking in PMU development

“…Since the control is defined as a function of distant bus variables, synchronized measurements are a good way of sending remote measurements to the controller [3]. Computer Model Validation: Last but not least, the validation of computational models of transmission and generation systems can be done by comparing results from these models with data from real systems obtained by PMUs [4].…”
