A Test Of The Renewable Resources Model Of Multiple Gains And Multiple Losses, Sandra C. Jones
A Test Of The Renewable Resources Model Of Multiple Gains And Multiple Losses, Sandra C. Jones
Sandra Jones
Eight choice scenarios were used to test Linville and Fischer's (1991) Renewable Resources Model, which predicts that people will prefer to separate multiple gains over time and also to separate multiple losses over time, the latter prediction being contrary to Kahneman and Tversky's (1979) Prospect Theory. The Renewable Resources Model was tested under conditions that, theoretically, should enhance the dual separation outcomes. However, in seven of the eight choice scenarios, complete reversals of these outcomes were observed B that is, the participants in the experiments preferred to combine multiple gains and to combine multiple losses. Explanations of these unexpected results …
Comparative Analysis Of Dynamic Line Rating Models And Feasibility To Minimise Energy Losses In Wind Rich Power Networks, Mathew Simms, Lasantha Meegahapola
Comparative Analysis Of Dynamic Line Rating Models And Feasibility To Minimise Energy Losses In Wind Rich Power Networks, Mathew Simms, Lasantha Meegahapola
Dr Lasantha G Meegahapola
Wind power generation has indicated an exponential increase during last two decades and existing transmission network infrastructure is increasingly becoming inadequate to transmit remotely generated wind power to load centres in the network. The dynamic line rating (DLR) is one of the viable solutions to improve the transmission line ampacity during high wind penetration without investing on an additional transmission network. The main objective of this study is to identify the basic differences between two main line rating standards, since transmission network service providers (TNSPs) heavily depend on these two standards when developing their line rating models. Therefore, a parameter …

Modern doubly-fed induction generator (DFIG) wind turbines have significant reactive power control capability, even during low wind speed conditions. This can improve system security by providing terminal voltage control at buses in the system. Generally, such control employs the full range of reactive power production from the turbine which can lead to increased system losses. By utilizing optimal power flow analysis, and limiting the range of reactive power production at certain wind farms, system losses can be minimized. If the reactive power of the wind farms are optimized to achieve the minimum system losses this may adversely affect the voltage …
