“…Existing conventional and renewable plants are calibrated in (J. Chen, P. Shrestha, S. Huang, N. D. R. Sarma, J. Adams, D. Obadina, and J. Ballance, 2012) using PMU data to help determine the cause of faults within the system. The dynamic parameter identification uses a combination of particle swarm optimization (PSO) and sensitivity analysis for a system consisting of a wind turbine, its reactive power support, and step up and step down transformers.…”

The power industry heavily relies on power system modeling to understand system operations, perform system planning studies, and identify and correct problems that arise within the system. By minimizing the error between the models and actual physical system, it can be ensured that the models provide representation of both the existing and future the power system. Many of these models in the system are user-defined, i.e. they are specialized representations of a specific system component in the system. It is important that these customized models produce an accurate response. However, maintaining such models is costly, so it is of value to determine if those models can be replaced with a generic model. Phasor measurement data can be used to calibrate model parameters and reduce error. In this paper, this process is automated for a generator in the Itaipu power plant using RaPId, a MATLAB toolbox that integrates measurements, models using Modelica/FMI standards, and optimization routines. This is achieved by using a combination of particle swarm optimization (PSO) algorithm and classical gradient optimization routines to calibrate the model parameters. In this paper, the calibration of a generic model of a synchronous generator, automatic voltage regulator, and power system stabilizer are estimated and compared to the user-defined models for an automatic voltage regulator, power system stabilizer, and turbine governor.

Phasor measurement units (PMU) are playing an increasingly important role in power system dynamic security monitoring and control. However, the wide-area deployments of the renewable energy sources and the high voltage direct current (HVDC) transmission bring a large number of inter-harmonics to the power grid, which may result in further power system security problems. The impacts of inter-harmonics on synchrophasor measurements are revealed. This paper derives the phasor expressions of the signal, which contains the fundamental component and the inter-harmonics. It is found that the inter-harmonics will lead to the subsynchronous oscillation of the phasor measurements. The frequency transmutation principle between the harmonic and the phasor oscillation is revealed. Then, the field PMU data recorded during a subsynchronous oscillation, which occurred in an area of China with a high concentration of wind farms and HVDC transmission lines, are studied. A geographical wiring diagram with the subsynchronous oscillation distribution depicts the severe consequences of the inter-harmonics. In addition, the correctness of the theoretical derivation and the possibility of the inter-harmonics monitoring are verified.
