Tutorial B4: Application of VSC-HVDC in a System Black Start Restoration

Presenters: Arash Fazel Darbandi, Christian Winter, Kasun Samarasekera, Zhibo Wang, Kay Leiteritz and Osman Abdi

This tutorial introduces Black Start Restoration (BSR), a set of procedures used to re-energize a power system after a rare but high-impact wide-area blackout by an VSC HVDC. Because blackouts can disable critical infrastructure and impose significant economic costs, restoration planning and repeatable technical guidance are essential for system operators and other stakeholders. The tutorial focuses on how Voltage Source Converter (VSC) High-Voltage Direct Current (HVDC) transmission can support BSR as an increasingly available and flexible alternative to traditional synchronous-generator-based approaches. The tutorial outlines practical guidance and study methods for implementing and validating VSC HVDC–assisted black start, covering the topics below based on the recent work completed by CIGRE WG B4.94.

- Identify the capabilities and limitations of VSC HVDC in the BSR.
- Define general specifications and design requirements for BSR with VSC HVDC.
- Electromagnetic Transient (EMT) and real-time simulation (RTS) modeling requirements for BSR with VSC HVDC. This is to verify the VSC control and protection functionality during BSR.
- Identify the potential interaction between VSC HVDC and the AC network during a BSR and between VSC HVDC and the source of energy driving the BSR.
- A case study to demonstrate the feasibility of renewable resources, i.e. offshore wind farm, for BSR.
