This book describes the BCU method (Boundary of Stability Region Based Controlling Unstable Equilibrium Point method). Widely accepted around the world, the BCU method is the only direct method used in the power industry. BCU methods have been adopted by at least 12 major utility companies (4 in Asia and 8 in North American), and the BCU method is the only direct method adopted by EPRI (Electric Power Research Institute) in its latest version of DIRECT 4.0. BCU methodology has been awarded 4 US patents. This book covers theoretical foundations of direct methods, energy functions, and the BCU method. It also explores the group-based BCU method and its applications. It includes numerical studies on industrial models and data.
