Abstract: A method and system for operating a wind farm by reconciling performance and operational constraints is disclosed. A wind farm may be subject to wakes, thereby reducing performance In order to lessen the effects of wakes, wake steering of the wind turbines may be performed. Specifically, both an operationally-independent analysis (such as by using a computational fluid dynamic model) and an operationally-dependent analysis may be performed, and the outputs of each analysis may be reconciled in order to determine whether (and how much) to wake steer.

Abstract: The present invention relates to a method of controlling the roam of a terminal user in the NGN network system, including: dividing the network into regions in accordance with IP address field and defining the roam type and service attribute of each IP address field when the terminal user roams to each region; defining the roam right of the terminal user in a core control device according to the roam type; when the terminal registers with the core control device from a region, IP address of the terminal being uploaded to the core control device, and the core control device obtaining the roam type of the terminal in accordance with the IP address of the terminal; then judging whether the terminal user has such roam right of this roam type, if positive, the terminal registering successfully, otherwise failing; when the terminal registers successfully, the terminal user is able to use the network service and some service attributes in the region.
