MANFRE, Daniel  y  BREA, Ebert. Design of a methodology to improve the investment project portfolios in an electric power system. Rev. Fac. Ing. UCV [online]. 2015, vol.30, n.1, pp.115-130. ISSN 0798-4065.

An Investment Project Portfolio in an Electric Power System (IPPEPS) is considered in this article as a set of enhancement projects to increase the installed capacity of an Electric Power System (EPS). These enhancement projects can consist of the installed capacity of power plants or transmission lines of the EPS. This paper develops a methodology to improve the IPPEPS. This consists in estimating the time where the investment projects should be carried out, and the amount of average active energy that each investment project must enter to the EPS, in order to improve the economic balance of the electric utility and decrease the forecasted not covered consumption of average active energy. Since the improvement of the IPPEPS falls into an optimization problem, this paper uses the Integer Mixed Simplex Algorithm (IMSA) to solve this problem. The methodology developed in this article uses Monte Carlo simulation to model the randomness of the EPS. This methodology is formulated in pseudocodes and is implemented in a numeric example whose results are analyzed by some statistical tools.
