“…However [23], and more recently with specific systems-level considerations [24][25][26], there is no existing technique which is both readily compatible with the network models developed and offers full multimode operation that could be employed. As such, the lowest acceptable level of fidelity for the VFAC and hybrid AC/DC network models is the behavioral level.…”

“…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.

“…Generally, MMC models are developed with a pre-determined modeling outcome in mind. Low-order average-value models are inherently unable to capture transients of high frequencies, and detailed models naturally include as much detail as possible within the simulation bandwidth [8].…”

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.
