   A Way Forward to Achieve Interoperability in Multi-Vendor HVDC System
By Adil ABDALRAHMAN [View]
[Download]

Abstract: Interoperability for multi-vendor voltage source converter-based high voltage direct current (VSC-based HVDC) systems has been recognized as a new challenge. However, interoperability for multi-vendor power-converter-based islanded systems is not new. For example, well established practices and standards can be found in the areas of railway power supply and rolling stock. This paper provides a brief review of the challenges, and research completed in this area. Guidelines and standards developed to address these challenges will be summarized. A comparison between islanded systems with power converters for railway power supply and multi-terminal HVDC (MTDC) systems is presented. Finally, a way forward to achieve interoperability for multi-vendor VSC-based HVDC systems is described.

   Aspects of stability issues of HVAC/HVDC coupled grids
By Gianni BAKHOS [View]
[Download]

Abstract: This paper explores MTDC control expectations and attempts to investigate the challenges preventingusage of MTDC grid to enhance power system stability. Protection and dispatching are not in the scopeof this paper. Dynamic performance up to tens of seconds is only considered (AC voltage regulation istherefore not studied here).

   DC Side Impedance for Handling Interoperability of Multi-vendor Multi-Terminal HVDC Systems
By Ashkan NAMI [View]
[Download]

Abstract: Using equivalent impedance to address possible interoperability issues is a well-established practice inelectric rail systems and it is also a feasible approach for investigating DC-side control interactions,thereby avoiding or mitigating possible interoperability issues in multi-vendor multi-terminal high voltage direct current (HVDC) systems. This paper presents different aspects related to DC-side equivalent impedances which may be necessary to be considered in practice.

   Modeling the impact of grid-forming E-STATCOMs on inter-area system oscillations.
By Alberto BOLZONI [View]
[Download]

Abstract: The reduction of physical inertia in power systems represents one of the major trends affecting publicgrids operations. Under this scenario, it becomes crucial to assess the positive contribution achievablethrough the application of advanced control strategies to converter-based units at the transmission anddistribution levels. In this perspective, this paper analyzes how the introduction of grid-forming controlfunctionalities in STATCOM devices could help toward the stabilization of the network transients andthe reduction of inter-area phenomena.

   Modular STATCOM for compensation of reactive power and voltage asymmetry in medium-voltage distribution power grids
By Josef TENGL [View]
[Download]

Abstract: A cost-effective STATCOM is proposed and discussed in this paper. Its modular topology enables toscale the power to target systems. Besides reactive power, the proposed STATCOM enables togenerate a zero-sequence component and compensate the voltage asymmetry, e.g., in widely spreadmedium-voltage distribution power grids with resonant grounding.

   Steady State Simulations of a Hybrid HVAC/HVDC Network Using OS Based ARM Devices
By Ioan DAMIAN [View]
[Download]

Abstract: For steady state calculations, all approaches make use of established computing devices (mostly PCs with x86-64 or x86-32 architecture) and environments that offer excellent performance but at a high cost. This paper presents an innovative alternative that is based on emerging technologies which have an ARM architecture, are still able to run powerful software, yet meet cost requirements that are less than 60 USD.
