Sažetak

Power system collapses are among the primary challenges in modern grids. Today's power grids face stressful conditions day by day. The increase in electricity consumption, the expansion of electrical networks, and the oldness of protective equipment are among the stressful items in today's networks. In this stressful situation caused by the low stability margin in power networks, load shedding (LS) is the last solution to prevent power system collapse. Various conventional and independent LS programs will no longer respond to the existing conditions. Therefore, the load-shedding scheme considering the existing conditions and appropriate to the types of instabilities is very necessary. To improve the load-shedding programs, various methods are suggested in the articles. The expansion of wide-area measurement systems and increasing use in electrical networks have made it possible to be more maneuverable in load-shedding programs than before. Hence, a new adaptive LS approach is proposed based on the combined instabilities, which shows better behavior than the existing programs. Validation of the suggested approach is investigated in a real power grid.
