When John Grainger began revising William Stevenson’s classic Elements of Power System Analysis, he realized that a complete modernization was in order. By the time he finished, an entirely new book was written, re-titled Power System Analysis. Covering such topics as power flow, power system stability and transmission lines, Power System Analysis teaches the fundamental topics of power system analysis using logical discussions and numerous examples. The new chapter on power system state estimation incorporates the latest developments in the field, and the discussion of system control covers economic factors of line losses and penalty factors. The loyal following earned by Stevenson will surely enjoy the modern power system analysis presented here..
