“…On the other hand, the voltage sag at power supply site is determined by the power system topology, fault type and location, transformer connecting mode, , and so on. Therefore, the customer's complaint due resulted by voltage sag is multi-uncertain that can be presented by an interval data easily [5] .…”

To meet power customers’ satisfaction is the essential responsibilities of utilities. Considering the property of customer’s satisfaction degree, an analytical interval assessment method of voltage sag is proposed. The customer satisfaction degree is presented by interval number corresponding to the voltage tolerance for the tested equipment installed at the customer side. Based on the determination function derived from the relationship between the voltage magnitude and the length of fault line in the power system, critical fault positions are determined through analytical iterative algorithm. By the variation of satisfaction degree within a given interval, the interval sag frequency is calculated. Moreover, the quantitative sag frequency is determined by the help of the interval sag frequency. The proposed method is applied to a five-bus system and IEEE 30-bus testing system. The simulation results comparing with existing methods have shown that this method is credible and suitable for the practical engineering application.

To meet the power customer's satisfaction is the essential responsibility of the utilities. Considering the property of customer's satisfaction degree, an analytical interval assessment method of voltage sag frequency is proposed. The customer satisfaction degree is presented by an interval data corresponding to the voltage tolerance of tested equipment installed at the customer side. Based on the determination function derived from the relationship between the voltage magnitude and the length of fault line in the power supply system, the critical fault positions are determined using analytical iterative algorithm. By the variation of satisfaction degree within a given interval range, the interval sag frequency is calculated. Moreover, the quantitative sag frequency is determined by the help of the interval sag frequency. After plentiful theory analysis, the proposed method is applied to a five-bus system and IEEE 30-bus RTS test system. The experimental results are compared with those from existing methods. It has been proved that the proposed method is so credible and simple that it is suitable for the practical application.
