A Survey of Interconnection Requirements for Wind Power

Abstract

Currently, more wind power is expected to enter into the electrical network all over the world. Therefore the power system becomes more vulnerable and dependent on the wind energy production. The European countries with already grid connection requirements for wind power have revised them in the last two years while other countries have started to address these requirements. In all cases the grid codes reflect the penetration of the wind power into the electrical network both at distribution and transmission levels or a future development is prepared with these demands. Issues as power controllability, power quality, fault ride-through and grid support capability during network disturbances are addressed through these demands. The present paper provides a world wide overview of the existing grid codes for wind power
