Distribution System Modeling and Analysis, Third Edition

Thought to be the only dedicated textbook focused on computational modeling for electric power distribution systems, this second edition clearly explains the principles and mathematics behind these models and provides approximation methods that help students recognize when a result is not what it should be. Using the same authoritative yet accessible approach found in the first, this edition is updated to reflect the latest changes and advances in the field. Finding strength in detail, this text brings engineers worldwide up-to-speed on the modeling and analysis of a distribution system.
