ELECTRIC POWER SYSTEMS, 5TH ED

Details

Electric Power Systems has been an essential book in power systems engineering for over thirty years. Bringing the content firmly up-to-date whilst still retaining the flavor of Weedy's extremely popular original, this Fifth Edition has been revised by experts Goran Strbac and Nick Jenkins. This wide-ranging text still covers all of the fundamental power systems subjects but is now expanded to cover increasingly important topics like climate change and renewable power generation. Updated material includes an analysis of today's markets and an examination of the current economic state of power generation
