Contribution tho the eletric power systems economic planning: an algorithm for the simultaneos expansion of generation and transmission using linear approximation. Economic Planning of Generation and Transmission in Electrical Power Systems constitutes a Nonlinear Optimization Problem which has some complexity and must be treated in a global manner. Several iteractive methods has been proposed to solve problems of this nature but sometimes are unaceptable due time and large computer storage requirements. This complexity is enlarged if generation and transmission were simultaneously optimized. Linear programming has been considered as a promissing tool to solve these problems but due the linearization of nonlinear functions the results presents some loss of accuracy, even so, for planning purposes these results are aceptable. In this work we propose a Global Algorithm for the Economic Planning of Simultaneous Expansion of Generation and Transmission in Electrical Power Systems based on the application of a Linear Programming Method and Minimum Cost Flow Algorithm which permits discret addition of generation and circuits units to the system with minimum investment cost in each period. Losses and maximum capacity of the lines are included in the algorithm, some examples are shown and at the end we suggest some extensions to further works.
