Optimal Load Shedding for Voltage Collapse Prevention Following Overloads in Distribution System

Load shedding is generally regarded as the final option to evade voltage collapse and blackout following major overloads. The traditional method of load curtails random loads regardless their importance until system’s improved. Shedding without considering priority will lead power interruption in vital infrastructures. Hence, improve existing system protection scheme, development a more effective efficient necessary. In this paper, an optimal under (UVLS) proposed for optimum prediction amount shed best location curtailment. Moreover, designed maintain during process. work, stability index (SI) feed-forward backpropagation neural network (FFBPNN) were adopted avoid by mitigating instability overloads distribution system. performance several overload scenarios investigated. Case studies performed on IEEE 33-bus exposed significant robustness recommended technique. Compared other approaches, approach counteracting under-shedding occurrence, enhancing profile, improving system, whilst maintaining shedding.
