- W2391657360 abstract "A relatively complete power grid security assessment index system, which includes five categories, i.e., its secure power supply ability, the security of its static voltage, the vulnerability of its topological structure, the transient security and risk indices, is proposed. The proposed index system can reflect security level of power grid reasonably and overall to offer quantificational basis for drafting emergency measures for power grid security. Traditional assessment indices and methods for power grid security are improved; the indices, such as the number of lost grid components after the N?K contingency, the index of maximum power supply regions, the utility theory based risk indices of overload, low voltage, voltage collapse and angle instability are given. As a practicable auxiliary tool for the planning, renovation and secure operation of power grid, power grid security can be calculated and analyzed conveniently by the proposed index system. Finally, taking a certain power grid for example, the reasonableness and practicability of the proposed index system are verified." @default.
