Ukraine Power System Support Project (UPSSP): Winter 2014/2015 Ukraine Power System Dynamic Analysis (Phase II)

Ukraine Power System Support Project (UPSSP) was established in September 2014, as sub-regional project with aim to investigate the technical potential of the regional high voltage networks to support strengthening Ukraine transmission network reliability. First phase of the project included a study that assessed the high voltage transmission network’s stability in response to curtailed gas and coal-fueled electric generation and expected increased demand for electricity resulting from consumers switching to electric heat.

Next phase of the project considers further stability analysis taking into account dynamic stability aspects, in particular in terms of huge power plant’s outages and voltage stability. Previous phase identified some potentially critical points from steady state analysis point of view, real behavior of the power system during observed (realized) hours recognized some others and dynamic stability study should examine all of them in more detail.

Type of services provided:

• Investigation of current status of the Ukraine power system, including damaged elements in Eastern part or the country
• Updating of previous phase assumptions and simulation models, as well as their improving in terms of dynamic stability analysis
• Recalculation of necessary remedial action schemes based on updated simulation models and identification of some critical points
