PV And Q V Curve Analysis Of IEEE 9 Bus System
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
Voltage Stability analysis of voltage instability in electric power system is very crucial in order to maintain the equilibrium of the system.Voltage security is the ability of the system to maintain adequate and controllable voltage levels at all system load buses.The main concern is that voltage levels outside of a specifiedrange can affect the operation of the customer’s loads. This paper presents the analysis of voltage instability of electric power system by using power-voltage (PV) curve and reactive power-voltage (QV) curve. Introduction:-Voltagestability is an important aspect of any power system design as it assures the system has sufficient power to meet the load demand. Power system voltage instability is related to the lack of reactive power resources in the network and the voltage can collapse when the power limit of a system is exceeded. Voltage stability in the power system is defined as the ability of a power system to maintain acceptable voltages at all bus in the system under normal condition and after being subjected to a disturbance. In the normal operating condition the voltage of a power system is stable, but when the fault or disturbance occurs in the system, the voltage becomes unstable this result in a progressive and uncontrollable decline in voltage. Voltage stability is sometimes also called load stability.
