The use of power system stabilizers has become very common in operation of large electric power systems.The conventional PSS which uses lead- lag compensation, where gain settings designed for specific operating conditions, is giving poor performance under different loading conditions. Therefore, it is very difficult to design a stabilizer that could present good performance in all operating points of electric power systems. In an attempt to cover a wide range of operating conditions, Fuzzy logic control has been suggested as a possible solution to overcome this problem, thereby using...

This book is a short introduction to power system planning and operation using advanced geometrical methods. The approach is based on well-known insights and techniques developed in theoretical physics in the context of Riemannian manifolds.
The proof of principle and robustness of this approach is examined in the context of the IEEE 5 bus system.
This work addresses applied mathematicians, theoretical physicists and power engineers interested in novel mathematical approaches to power network theory.
