Voltage Stability Assessment of Wind Integrated System for Variable Wind Speed with FACTS Devices

Abstract

Requirement of power utilization is increasing exponentially both by industrial usage as well as in our day-to-day life due to inclusion of latest developments in the technology and automation. So, increase of power generation from conventional as well as non-conventional type of energy resources to meet these challenges is also needed. This increase in power generation is not possible alone by existing methods. Wind energy and integration of wind energy system with existing systems to increase the power generation is one of the methods to meet day to day need of high power demands. Though, an integration of wind system needs some compensation techniques to increase the power generating capacity of multimachine machine system. Reactive power compensation or drop in voltage of various buses of the system is needed from the stability point of view. Inclusion of FACTS, devices to boost active power proves to be good method for this purpose especially when the system is integrated with renewable energy resources. Based on simulated IEEE-14 Bus wind integrated system provided by PSAT, the performance of various FACTS devices needs to be checked, so that variations in the bus voltages of the integrated system can be controlled to improve the stability of the system. In this paper Identification of various week buses by Line Voltage stability indices are presented with in the composite system so that placement of suitable FACTS devices can be done to improve the performance of the system.
