This the default, no action method; avoidance zones are not considered.

This method allows the user to specify a table that defines the conditions in which the turbines should not be operated.

See “Unit-level Constraints” for descriptions of added constraints.

See “Unit Head Based Avoidance Zones” in Objects and Methods for slot descriptions.
