Abstract This paper is dedicated on investigation of the Future power systems (FPS). FPS will contain a considerable volume of distributed energy resources. The present study is dedicated to the investigation of the future power systems (FPS) that contain a considerable amount of DG. Exact prediction of the structure, composition, and parameters of such systems is impossible. It makes necessary to perform calculations that correspond to various combinations of the types of DGs used, their connection places, disturbances that may cause a loss of dynamic stability. One of the main requirements for the system development and operation is the existence of a sufficient dynamic stability reserve. The future states of FPS are unknown with need in appropriate modelling techniques. The automation procedures have been developed for stability reserve estimation in the FPSs that contain a considerable volume of DER. Considering unintended islanding, surviving strategy requires operation of DER is prolonged with supplying customers when loss-of-mains happens. Technical requirements for distribution grid surviving and reconnection are considered in the paper. Additional automation shall resynchronize the distribution network after its emergency disconnection from the transmission part.
