The extensive connection of distributed generation (DG) with the distribution network (DN) is one of the core features of a smart grid, but in case of a large number, it may result in problems concerning the DN-DG compatibility during fault isolation and service restoration, for which no efficient and economic solutions have been developed. This paper proposes a doubly-fed induction generator (DFIG) adaptive control strategy (ACS) and a coordination technology to be compatible with the typical feeder automation (FA) protection logics in the ring distribution system. First of all, an ACS simulating the inertia/damping characteristics and excitation principles of synchronous generators is developed to achieve seamless switching between DFIG grid-connection/island modes, and make distant synchronization possible. Next, a technology coordinating the DFIG islands controlled by ACS and the remote tie-switches based on local inspection of synchronization conditions for closing is developed to achieve the safety grid-connection of DFIG islands in the absence of DN-DG communication. At the last, a detailed simulation scenario with a ring DN accessed by five DFIGs is used to validate the effectiveness of ACS and coordination technology compatible with FA in various faults scenes.

Due to the constantly increasing intensity of the air traffic flow, the capacity of a particular sector of airspace reaches its predetermined value. More than 60% of all air traffic of the Russian Federation falls on the Moscow airspace and its intensity is constantly growing. The effective organization of air traffic in an aviation hub control area depends on the ability of air traffic controllers to correctly align the order of arrival and departure of aircraft with the existing traffic intensity, prohibitions and restrictions, meteorological conditions and other factors. This article considers the problematic aspects of the coordination between ATC units, leading to delays in departing and approaching aircraft, affecting the safety, efficiency and regularity of air traffic. The rules of coordination between adjacent ATC sectors, providing aerodrome dispatching service in the Russian Federation are described. The description of the coordination process between the Ostafievo Airport ATCs and the controllers of adjacent dispatch centers is given. These adjacent ATCs are the following: the Vnukovo-Radar, the Domodedovo-Radar, the FIS Vnukovo-1 and the FIS Vnukovo-2, also the ATC Tower of the state aviation. The analysis of the existing technology of ATC coordination in one aviation hub is carried out. Recommendations for improving the effectiveness of the coordination system between ATC units are presented.
