Interaction Assessment of VSC-HVDC links using EMT-type tools Workshop
Large integration of renewable energy sources and HVDC converters in power system have resulted in displacement of conventional power generation, lower system inertia and lower short circuit capacity of the AC power system. The AC grids integrate multiple converters in the close vicinity that potentially influence each other. The interoperability and stability of the system with massive amounts of converters is regarded as a key issue in future power systems development.
In recent years large-scale integration of solar, wind and HVDC converters, have resulted in several stability problems in the power system. Interactions phenomena between VSC-HVDC converters and other power electronics devices or passive HV components installed on the network, can have a wide range of frequencies: from interarea oscillations, to sub-synchronous interaction (as SSRI and SSTI) and even to high frequency interaction (between 100Hz till several kHz). In addition, interactions due to non-linear behaviour such as transformer saturation, control non-linearity, etc. can also occur.
EMT-type tools is commonly used to study and investigate such interactions phenomena between VSC-HVDC links and other HV equipment. The aim of this workshop is to provide an overview on interaction assessment related to VSC-HVDC links. The following aspects will be addressed:
- Methodologies to analyse and to assess interactions in AC networks with multiple converters
- EMT-type tools (offline and real-time) and models that are required to perform such studies
- Practical experiences of interaction assessment in real projects
- Risk assessment and/or solutions to prevent such interactions
