Abstract
Increasing extreme weather events, partly driven by climatic issues/global warming, motivated relevant studies and planning for strengthening power system resiliency. Due to such highly impactful weather events, power systems infrastructure and operation are significantly affected. Therefore, to minimize the impact and the extent of the event-driven damage to the grid, there is a pressing need for adequate preventive and resiliency planning. This paper presents an approach to improve the voltage and the line loading profiles of large-scale wind integrated power systems during such disruptive events to maintain the reliability of the healthy part of the transmission systems during/after the event. This study considers outages of multiple buses, transmission lines, loads, and generators. By exercising the volt-var control at wind farm buses during these contingencies (failure of different buses, loads, and generators), the operational profile of the healthy part of the systems has been improved. The developed strategy has been tested on the IEEE-39 bus system designed in DIgSILENT Power Factory. The work outcomes show that volt-var control significantly improves the operational profile of the healthy part of the system with an increasing penetration level of wind generation during and post extreme events.
