New multi-criteria-based algorithm for islanding detection in smart grids

摘要: Islanding detection methods can be divided into communication-based and local detection-based methods. Proposed passive have traditionally been dependent from the distributed generation unit type. A large non-detection zone near a power balance situation unwanted tripping due to other network events also major challenges with traditional, islanding In this paper, new multi-criteria-based algorithm is presented. This able, based on measurements, detect very fast selectively situations in perfect without zone. The multi-criteria measures changing natural response of voltage unbalance total harmonic distortion parameters as well intelligently utilizes available fault information. With algorithm, no nuisance likely occur or disturbances it not
