Sensitivity based Load Shedding Strategy for Avoiding Voltage Instability
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 4
Abstract
Distribution networks (DNs) are being operated closer to the voltage stability boundaries due to the exponentially increasing power demand. This paper presents a sensitivity based load shedding strategy for averting the occurrence of voltage instability in DNs. This method identifies the most sensitive node through evaluating the sensitivity between the voltage stability and real power demand at each node and performs load shedding at the chosen node; and repeats this process till the network enters the stable region. The method improves the bus voltage profile besides avoiding voltage collapse. The simulation results on two test systems emphasize its applicability on networks of any size.
