review of computer tools for analysing the integration of renewable energy into various energysystems
FREE-DOWNLOAD D Connolly, H Lund, BV Mathiesen… – Applied Energy, 2010 This paper includes a review of the different computer tools that can be used to analyse the integration of renewable energy. Initially 68 tools were considered, but 37 were included in the final analysis which was carried out in collaboration with the tool developers […]
Transformer based voltage sag generator to test renewable energy systems during grid faults in the laboratory
FREE-DOWNLOAD C Wessels, T Wehrend… – EPE Wind Energy Chapter …, 2010 – A transformer based voltage sag generator to test renewable energy systems is presented. Design considerations concerning overvoltages and overcurrents during switching action are adressed. Mea- surement results of a 30 kW laboratory prototype testing a line side PWM
