Four interconnection requirements, related to local area operating characteristics of the power system, are analyzed: the steady-state voltage variation; the power margin; the low-voltage ride-through capability; and transient stability. The maximum integration level is first determined as limited by each individual interconnection requirement. Then, the maximum integration level complying with all interconnection requirements is determined. Results show that a wind farm with rated power up to 5.5–6.3 % of the short-circuit power, depending on the reactive power compensation, can be connected to a given grid point while respecting more recent grid codes.
