The development of Electric Power Systems (EPS) is intertwined with the development and qualitative improvement of human life, which is why their analysis to ensure their proper functioning is of vital importance. This book deals with the study of load flow, which assesses the behavior of EPS in a steady-state operation, and the study of short circuits, which determines the currents and voltages in EPS during various types of short circuits. To this end, appropriate mathematical models are developed, describing the behavior of EPS in each of these studies and the computational techniques used to solve the equations that arise to assess the behavior of EPS. From this presentation, the usefulness of these studies in the design and operation of EPS is established. An essential supplement to understanding the issues related to Electric Power Systems Analysis is the problems and their solutions found in the appropriate chapters. To achieve the best possible outcome, the reader of the book should refer to the solution of the problems only to confirm the correctness of their own solution or if their own efforts to solve them were unsuccessful. The problems solved have been selected to clarify the significant issues that arise when solving the difficult problems of EPS. Their goal is to convey to the engineer the methodology of thinking for solving problems using traditional and modern methods.
