What the Paper Adds to the Subject Area as Compared to Past Literature
Multiple studies have analyzed wind resources distribution and its significance in characterising the stability of interconnected power networks. The article focuses on an area with limited literature. It examines large disturbance stability issues: rotor angle and voltage stability in power networks. The study is specifically based on geographically distributed wind resources in the context of dispatch situations based on profiles of historical and geographical wind generation. The authors’ focus adds to the existing literature about the characterisation of these networks interconnected with distributed wind generation.
For example, the study findings indicate that network regions with increased penetration rates for wind and conventional generation consist of detrimental stability concerns based on their old-fashioned features. Other studies illustrate that the dominance of either conventional or wind generation can advance or progress the transit and voltage stability of the network. The study proposes the use of equipped enhanced FRT strategies in farms to intervene DC-link transients as well as ease activation of the crowbar and advance stability. Hence, the study adds to the subject area as compared to other published research journals.
Current Research Gaps Based on this Study
Currently, there are many areas pertaining to the characterisation of large disturbances rotor angle and voltage stability that are integrated with power networks within wind generators. This study focuses on a specific area to address research gaps regarding wind generation. For example, multiple studies have examined interconnections between networks and how they create local as well as centralized stability concerns founded on their proximity or regional capacity of conventional or traditional generators. However, few have scrutinized the large disturbance stability issues relating to voltage and rotor angel stability and how they influence power networks based on the distribution of resources geographically.
The study notes that stability surveys based on variable-speed wind generation systems (DFIGs) are limited in regards to simplified network structures and issues relating to fault concerns, which underscores a potential area of study for future researchers. Hence, there are many areas in which upcoming researchers can concentrate on including investigating steadiness regarding stability issues based on the regional capacity of conventional generators.
The focus of Future Studies
This area of study is widely researched and documented; however, multiple areas can still be explored in the future. The research study outlines key areas relating to the subject that many studies, including this one, have failed to examine. For example, future surveys should focus on equipping DFIG wind farms with advanced FRT techniques to mitigate DV link transients; as a result, they would improve crowbar activation and advance firmness. Current DFIGs consist of all necessary conventional FRT methods, but their efficiency can be improved by the incorporation of modern technologies.
The penetration levels of these conventional FRT techniques can essentially improve the capacity of certain network regions resulting instability concerns in the event of network failures in the future. This underscores the significance of control strategy as it influences stability; however, steadiness features within these systems can remain unaffected regardless of the region or the control technique of the wind generator. Therefore, future studies can focus on many areas, as mentioned above to improve the functionality of wind generator and their functions.
