The most load shedding (LS) schemas proposed so far used voltage and frequency parameters via under-frequency (UFLS) and under-voltage (UVLS) LS schemes, separately. The under-frequency and under-voltage relays are working in the power system without any coordination. In this paper, the necessity of considering both of voltage and frequency indices to achieve a more effective/adaptive and comprehensive LS strategy is illustrated. It is also clarified that this problem will be more dominated in the presence of wind turbines. Finally, an effective LS scheme considering both system frequency and voltage characteristics is addressed.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
