“…Modeling using dynamic phasors has been applied to such complex systems as LCC-HVDC, VSC-HVDC, and wind energy systems [9][10][11]. A preliminary (and only low-order) dynamic phasor model of an MMC system is presented in [12,13] wherein the eigenvalues of the system are studied; the presentations in [12,13], however, do not include any validation of the model.…”

Abstract. This paper presents a model for a Modular Multilevel Converter (MMC) using extended-frequency dynamic phasors. The model is based upon a series of harmonicfrequency representations that are obtained for the fundamental and dominant harmonic components. Depending on the requirements of the study to be conducted and the desired level of model accuracy, a low-order model (i.e., average-value) or an arbitrarily wideband model may be constructed. The paper describes the principles of modeling using extended-frequency dynamic phasors, and applies them to an MMC connected to a power system represented using a Thevenin equivalent. The model contains details of the MMC's control system including its high-level control circuitry, as well as voltage balancing and synchronization components. The developed model is then validated by comparing it against a fully-detailed electromagnetic transient (EMT) simulation model developed in PSCAD/EMTDC simulator. Comparisons are made to establish the accuracy of the model (both its low-order and wide-band variants) and to assess the computational advantages it o ers compared to conventional EMT models.

“…In the simulation of asymmetric fault and waveform distortion, the non-fundamental component is generated, and the simulation result is not accurate enough. Based on the time-varying Fourier coefficients, the dynamic phasors method is used to model LCC-HVDC [4][5][6][7]. This model can reflect the dynamic behavior of the system, but it is an average-value model.…”

Abstract:In order to improve the simulation speed of the AC/DC hybrid grid, the inductance/capacitance (L/C) switch model for line-commutated converter of high-voltage direct current (LCC-HVDC) is presented in this study. The time domain modeling method is used to analyze the circuit of L/C switch model for the six-pulse system in LCC-HVDC in a switching period. A parameter setting method of L/C switch model is proposed considering the transient response, the steady state performance, switching losses and simulation error of the switch. The inductance/capacitance (L/C) switch model for LCC-HVDC has the advantage of keeping the admittance matrix unchanged regardless of the change of switching state, which improves the simulation efficiency. Finally, the validity of the parameter setting method is verified. Compared with the test results of PSCAD/EMTDC, the accuracy of the proposed LCC-HVDC simulation model is proved. The model is suitable for real-time or offline simulation of AC/DC hybrid grid.

“…The electromechanical transient model can reflect the fundamental component only and need less computing resources of computer. Moreover, the simulation models of HVDC systems based on dynamic phasors theory have been researched by the researchers [5][6][7]. The dynamic phasors theory can build the algebraic model of the converter based on a time-varying Fourier series of the time-signals and this algebraic model can include the fundamental component and the necessary harmonic components according to the accurate requirement of the modelling and simulation [7].…”

Abstract-This paper proposes a dynamic phasors model of HVDC systems including the converter, DC line and control when the AC systems are symmetrical and analyses the simulation process of the proposed dynamic phasors model. The proposed dynamic phasors model can rapidly reflect the dynamic characteristics of HVDC systems including the harmonics characteristics of the converter of HVDC systems at the AC system side. Simulation results among the dynamic phasors models and EMR model are compared and the simulation results confirm the validity and accuracy of the proposed dynamic phasors model.
