要約(日本語): 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. Then it is clarified that this problem will be more dominated in the presence of wind turbines. Finally, a general LS scheme considering both system frequency and voltage characteristics is addressed.
