Abstract
This chapter reviews the grid code requirements for integration of wind power plants (WPPs). The grid codes reviewed are from the UK, Ireland, Germany, Denmark, Spain, Sweden, the USA, and Canada. Transmission system operators (TSOs) around the world have specified requirements for WPPs under steady‐state and dynamic conditions in their grid codes. Steady‐state operational requirements concern the power factor requirement, voltage operating range, frequency operating range and voltage quality. The steady‐state operational requirements for WPPs are specified at the point of connection (POC). Low‐voltage ride through (LVRT) is a WPP's capability to stay connected under specified low‐voltage conditions at the POC, normally caused by faults in the grid. The UK grid code specifies LVRT requirements for both onshore and offshore WPPs. In some grid codes, WPPs are also requested to supply a maximum reactive current during specified low‐voltage conditions. The chapter describes the low‐voltage conditions at the POC that are specified in various grid codes.
