Assessment of dynamic phasor extraction methods for power system co-simulation applications
Elsevier
The paper examines a number of methods for extracting dynamic phasors (DPs) from samples of natural waveforms that are generated using electromagnetic transient (EMT) simulators. It delves into the theory underlying each phasor extraction method and the numerical routines used for their implementation and performs an analysis of the properties of the extracted phasors for general power system signals that may include various power system transient scenarios.
A Co-Simulation Platform for Modeling and Testing MMCs and Their Controls in Large Networks
IEEE
This paper presents a method to represent the dynamics of modular multilevel converters embedded in a large power system using a multi-rate co-simulation platform. The co-simulation platform includes dynamic phasor (DP) and electromagnetic transient (EMT) solvers. It uses large simulation time-steps in the DP subsystem for fast computations. The MMC model is embedded in the DP-side of the co-simulator. Modeling the converters control systems including non-linearities, are also discussed
A Method for Modeling and Testing MMCs and Their Controls in Large Power System Simulation Studies
Cigre Canada
In this paper, an average-value MMC model is developed using the concept of dynamic phasors (DPs). The paper also develops a novel method for modeling and testing nonlinear converter control blocks that are prohibitively difficult to implement in an average value model due to the ignored details of harmonic behaviour of internal waveforms. Important time-domain instantaneous measurements are combined with DP techniques to obtain accurate dynamic and control results.
Multi-rate co-simulation of power system transients using dynamic phasor and EMT solvers
IET
This study presents a novel multi-rate algorithm for the co-simulation of power system transients using base-frequency dynamic phasor solver for frequency adaptive simulation of transient (BFAST) and electromagnetic transient (EMT) solvers. The BFAST solver alters its solution technique from dynamic phasors to EMT based upon the frequency contents of the waveforms being simulated. It is then integrated with an industrial-grade EMT solver to develop a BFAST–EMT multi-rate co-simulator.
A Dynamic Phasor Model of an MMC With Extended Frequency Range for EMT Simulations
IEEE
This paper presents a new dynamic phasor (DP) model of a modular multilevel converter (MMC) with extended frequency range for direct interfacing to an electromagnetic transient (EMT) simulator. The internal dynamics of the MMC are modeled considering dominant harmonic components of each variable. The proposed model is validated against detailed EMT models built in PSCAD/EMTDC simulator. Experimental verification on a scaled-down laboratory setup is also included.
Design and Simulation of Single Phase Active Current Harmonic Filter
IEEE
This paper describes the basic design, control modeling and simulation of a single phase current harmonic filter. Modeling and simulation is done in the MATLAB SIMULINK environment. The filter consists of a current source inverter (CSI) with a front end fixed rectifier to obtain required dc voltage. This filter can eliminate harmonics up to about 50th order. Analog closed loop scheme is used to control the inverter. Basic simulation of the harmonic current filter, the control system and simulation results a
