Wide-Area Power Oscillation Damping Control (POD) in Nordic Equivalent System

Abstract A study is presented on power oscillation damping control (POD) using wide area measurements applied to a single static var compensator (SVC). An equivalent power system model representing key characteristics of the Nordic power system is used. Feedback signals from remote phasor measurment units (PMUs) in Norway and Finland are used to damp the critical inter-area modes through a large SVC unit located in south-east Norway. A comparison between two control design approaches -(i) model based POD (MBPOD) -dependant on accurate system model and (ii) indirect adaptive POD (IAPOD) -which relies only on measurements -is made. For MBPOD an optimization approach is used to obtain the parameters of the controller while the IAPOD is based on online Kalman filter estimation and adaptive pole-shifting control. It is shown that the IAPOD yields almost similar performance as the MBPOD with very little prior information about the system. The performance comparison is verified for several tie-line outages

Sexism and Attitudes toward Gender-Neutral Language : The Case of English, French and German.

We examined the relationships between three forms of sexism (Modern, Benevolent and Hostile) and two components of attitudes toward gender-neutral language (attitudes toward gender-related language reforms and recognition of sexist language) across different contexts. A questionnaire study (N = 446) was conducted among students in the United Kingdom and in two regions (French- and German-speaking) of Switzerland. While we generally hypothesized all forms of sexism to be related to negative attitudes toward gender-neutral language, attitudes were expected to be more positive and less related to sexist beliefs in a context where gender-neutral language is firmly established (the UK), compared to contexts where the use of such language is only recent (the German-speaking part of Switzerland) or still scarce (the Frenchspeaking part of Switzerland). We found that across all contexts modern and hostile sexist beliefs were indeed related to negative attitudes toward gender-related language reforms while, intriguingly, benevolent sexist beliefs were related to positive attitudes in the French-speaking part of Switzerland. Recognition of sexist language was significantly related to Modern Sexism only. Finally, British students were found to express more positive attitudes toward gender-neutral language (both components) than Swiss students
