The development of Electrical 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 load flow study, which estimates the behavior of EPS in a steady-state operation, and short-circuit study, which determines the currents and voltages in EPS during various types of short circuits. To this end, appropriate mathematical models are developed to describe the behavior of EPS in each of these studies and the computational techniques used to solve the equations that arise to estimate the behavior of EPS. From this presentation, the usefulness of these studies in the design and operation of EPS is evident.
An essential complement to understanding the issues related to Electrical Power Systems Analysis is the problems and their solutions found in the appropriate chapters. For the best possible result, 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 the problem were unsuccessful. The problems solved have been selected to clarify the important issues that arise when solving difficult EPS problems. Their goal is to impart to the engineer the methodology of thinking for solving problems using traditional and modern methods.
