This paper presents an evaluation of two control schemes for virtual inertia support from the converter terminals of an HVDC interconnection. A point-to-point interconnection between asynchronous power systems is assumed, where one terminal controls the dc-side voltage while the other controls the p...

This project presents a pre-State Estimation methodfor the detection of Bad Data (BD) in Phasor MeasurementUnits (PMUs) using correlation analysis and a Neural NetworkClassifier. Presented in this paper is the algorithm design, thesteps for generating training and testing data, and the metricsused f...

This article introduces a modulation technique for modular multilevel converter (MMC) in variable speed traction drives for electrical transportation referred as windowed pulsewidth modulation (W-PWM). The windowed PWM (W-PWM) is derived by blending the principles of operation of conventional modula...

Eigenvalue-based analysis of small-signal dynamics in High Voltage Direct Current (HVDC) transmission systems requires cable models that are compatible with a state-space representation. While distributed parameter models accounting for frequency-dependent effects are inherently incompatible with a ...

This paper presents a platform for testing wide area monitoring system (WAMS) applications in real time with a Hardware-in-the-Loop (HIL) approach. The power grid dynamics are emulated by performing real-time phasor simulations. Voltage and current phasors can be streamed to external systems based o...

In recent years the need for DC distribution buses has increased considerably. As it can be noticed in the transport for example the distribution systems of the more electric aircrafts, ships, or electric cars. Given the complexities of the systems presented above, the need to use more and more swit...

This paper presents an experimental performance evaluation of different control strategies for providing virtual inertia from power electronic converters. The evaluation is based on a laboratory-scale prototype of a point-to-point HVDC transmission system with Modular Multilevel Converters (MMCs). O...

This paper presents a technique for damping of oscillations in ac grids by control of VSC-HVDC links. The effect of the proposed controller is equivalent to a mechanical friction between two asynchronous networks (modelled as rotating masses) interconnected by the HVDC link. Therefore, the dynamics ...

This paper presents a distributed converter interface for the road-side infrastructure of dynamic inductive power transfer (IPT) systems for roadway-powered electric vehicles (RPEV). The proposed system configuration is based on a modular multilevel topology, with each individual module supplying po...
