client: CGES AD (Montenegro)

finishing date: March 2019 (October 2019)

team: Milan Stojanovic – Project Manager, M. Ivanovic

Main objective of the study was to analyze compliance of wind power plant’s Gvozd (54.6MW) selected wind turbines with the Montenegrin Grid Code, at selected point of common coupling suggested by the Investor. In order investigate the compliance of the WPP with Grid Code requirements, following activities have been performed:

  • WPP modeling and integration of the simulation model into the regional dynamic model in PSS®E and DIgSILENT PowerFactory software tools
  • Steady state analysis: Load flow and voltage profile analysis, N-1 contingency analysis, analysis of influence on active power losses, voltage regulation and reactive power control possibility assessment at PCC
  • Quasi-Dynamic Simulation (QDS) for one year time frame with 15 min sampling resolution with an aim of determining expected overload duration during one year period
  • Short circuit contribution analysis
  • Transient stability analysis: Capability analysis of wind generators to maintain stability and provide the required voltage support in cases of simulated voltage dips (Fault Ride Through) in the network
  • Mid-term stability: Transient stability assessment after severe system outages
  • Small signal stability analysis
  • Power quality analysis – Flicker contribution, harmonic distortion, voltage variations due to switching operations.
