Collective identities of VSCs: influencing factors and impact
European Journal for Sport and SocietyThis paper explores the positive effects and factors that shape collective identities within voluntary sport clubs (VSCs). As the role and development of collective identities in VSCs remain poorly understood, Classic Institutional Theory is combined with Social Identity Theory to identify the micro- and organisational-level factors that shape these ...

Performance assessment of VSC-based HVDC system in asynchronous grid interconnection: Offline and real-time validation of control design with symmetric optimum PI tuning [PDF]
Asynchronous interconnection is essential for integrating AC networks operating at different frequencies, typically 50 Hz and 60 Hz. This need arises from distributed power generation methods, including offshore renewable sources and diverse regional ...

High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

Fuzzy adaptive VSC systems [PDF]
, 1993 To design robust control systems, Variable Structure Control (VSC) is one of the modern control methods that could be used. This method is implemented using a discontinuous type control which usually includes linear feedback terms and signum terms.

High Voltage, EarlyView.ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.
