The nature of the programme is that almost all of the three individual packages will take more than a single year to complete, therefore they are not all expected to report specific milestones in 2016. The key expected areas of progress in 2016 include the following:

  • Deliverable for P40.016: develop and validate static and dynamic models of system components such as HVDC and loads, including completion of the VSC HVDC dynamic models that can be used in system planning studies. Additionally, methods for system-wide model validation based on measurements will be developed.

  • Deliverable for P40.022: develop probabilistic and risk-based planning methods and tools incorporating all sources of system uncertainty. Evaluate fault location algorithms to determine their suitability in estimating fault locations in networked transmission systems.

  • Deliverable for P40.023: develop methods and guidance for modelling transmission systems for evaluating the impacts of harmonic distortion which might result from specific occurrences such as geomagnetic induced currents flowing through system transformers or high levels of inverter-based resources.

The purpose of the grid planning programme is to address the following primary areas:

  • Model Development, Validation, and Management: develop computer simulation model for HVDC and dynamic load behaviour together with methodology to validate these models.
  • Develop new risk based analysis methods and tools that can be integrated with existing planning processes such that uncertainties in the planning environment are assessed and understood.
  • Special Planning Study Methods and Tools especially for evaluating the impacts of harmonic distortion: further development of existing analysis tools for FACTS and HVDC related devices
     
Progress for each P40 work package is expected during 2016. However, because this is ongoing research, not all of the packages will be completed or produce significant publications in that time. The success criteria are that most, if not all, of the set of deliverables will be achieved.
