MEJIA SULANILLA, Ana María; HINCAPIE ISAZA, Ricardo Alberto  and  GALLEGO RENDON, Ramón Alfonso. Optimal planning of distribution systems considering multiple objectives: investment cost, reliability and technical losses. Tecnura [online]. 2015, vol.19, n.43, pp.106-118. ISSN 0123-921X.

In this article, a method to solve the multi-objective planning problem of electric power distribution systems is proposed by means of using a non-dominated sorting elitist algorithm (NSGA-II). This method considers four mathematical models, where fixed costs, variable costs, fixed and variable costs, and network reliability are considered as objective functions. The set of constraints is comprised of technical and operational criteria. When all mathematical models are solved common elements to the solutions with each model are found. This process is repeated until a final configuration of the system is found. In this manner, in each step of the algorithm, sorts of cuts are generated, which reduce the solution space of the problem. The method is verified with a distribution system from the specialized literature, obtaining results that show the effectiveness of the method when an equilibrium point is found among all the objectives considered.
