Technical Requirements for Wind Power Plants Connected to the Electrical Grid in Finland and Market Analysis for Services of M.O.E.

Abstract

The energy transition from conventional to a more sustainable energy production leads to increasing requirements for grid integration of power generating facilities from renewable resources. At the same time, grid codes become more important and complex. This thesis analyses the technical requirements for grid integration of wind power plants in Finland and compares these with the requirements in Germany. Furthermore, it evaluates market chances for services of M.O.E. in Finland. In particular, the requirements in the Finnish grid code VJV2013 and the German VDE-AR-N 4120 are examined while considering the development of wind power in both countries. At present, wind power does not significantly influence the Finnish energy production and the technical requirements for grid integration of wind turbines in Finland are reasonable according to the currently installed wind power capacity. In specific parts, such as power quality and plant modelling, the VJV2013 is more stringent, but generally the requirements are not as extensive as in the German equivalent. Especially in terms of the upcoming European grid code NC RfG, the Finnish requirements will have to undergo further changes.
