“…The frequency response of the network as seen from a specific bus or node is the output. • Modal resonance analysis [17], [18] uses frequency scan results as input for modal analysis to determine the frequency at which harmonic resonance excitation or observation is most likely identified as seen from a bus. The results are based on evaluation of eigenvectors.…”

This paper presents a novel harmonic propagation model for the analysis of harmonic propagation in meshed transmission networks. This method is based on electromagnetic waves and uses scattering parameters known from microwave theory. The physical understanding of harmonic distribution in a power system is achieved. Changes may be quantified, and the method is validated against both physical harmonic distortion measurements and simulations. This method differs from traditional analysis methods in that the propagation pathways, as well as the contribution of individual sources to the propagated harmonic voltage in the entire network, can be determined unambiguously, allowing the influence of grid changes on the harmonic voltage to be predicted.

“…This example illustrates that the frequency scan study for each node impedance is not straightforward. Resonance mode analysis results described in more details in [38] are therefore needed in order to identify relevant resonance modes and contributing nodes. The considered network changes lead to resonance peaks vanishing, additional peaks appearance, resonance amplitudes decrease and peaks shift shown in Table I.…”

This paper introduces a special session on results of the Swiss competence center on energy research FURIES that has been established in coordination with the Swiss Energy strategy 2050 with the specific aim to develop, promote and deploy power grid-related innovative solutions toward the implementation of the Swiss Energy Strategy 2050. This contribution will report on activities within WP 3, "AC/DC multi-terminal grids and power electronics". This WP includes three subtasks with contributions from the major Swiss technical universities: Multi-terminal HVDC system design, fault detection and clearing in multi-terminal HVDC, enabling component and converter technologies and applications. The spectrum of the center's activities is briefly introduced and as an illustrative example, the contributions of the SCCER FURIES in relation with HVDC grids are summarized. These contributions include: new high power DC testing methods and laboratories, new DC breaker principles and fault location techniques, AC/DC grid resonance analysis and novel converter technologies.

“…Having said that, the energy transfer between AC and DC within the converter produces unusual harmonics although the pulse firing system is under control. It becomes a more serious issue when those unrepresentative harmonics damage the resonant networks, causing the operating status of the HV DC/AC operation to become complex [125,126].…”

Dynamic Modeling of HVDC for Power System Stability Assessment: A Review, Issues, and Recommendations

et al. 2021

High-voltage direct current (HVDC) has received considerable attention due to several advantageous features such as minimum transmission losses, enhanced stability, and control operation. An appropriate model of HVDC is necessary to assess the operating conditions as well as to analyze the transient and steady-state stabilities integrated with the AC networks. Nevertheless, the construction of an HVDC model is challenging due to the high computational cost, which needs huge ranges of modeling experience. Therefore, advanced dynamic modeling of HVDC is necessary to improve stability with minimum power loss. This paper presents a comprehensive review of the various dynamic modeling of the HVDC transmission system. In line with this matter, an in-depth investigation of various HVDC mathematical models is carried out including average-value modeling (AVM), voltage source converter (VSC), and line-commutated converter (LCC). Moreover, numerous stability assessment models of HVDC are outlined with regard to stability improvement models, current-source system stability, HVDC link stability, and steady-state rotor angle stability. In addition, the various control schemes of LCC-HVDC systems and modular multilevel converter- multi-terminal direct current (MMC-MTDC) are highlighted. This paper also identifies the key issues, the problems of the existing HVDC models as well as providing some selective suggestions for future improvement. All the highlighted insights in this review will hopefully lead to increased efforts toward the enhancement of the modeling for the HVDC system.
