LOPEZ-LEZAMA, Jesús M; BUITRAGO, Luisa F  and  VILLADA, Fernando. Location, Sizing and Optimal Contracting Price of Distributed Generation in Distribution Networks. Inf. tecnol. [online]. 2015, vol.26, n.6, pp.109-120. ISSN 0718-0764.

This work presents a methodology for the optimal location, sizing and contract pricing of distributed generation (DG) in distribution systems. The proposed methodology is based on the interaction of two agents: the owner of the DG and the distribution system operator. On one hand the owner of the DG aims at maximizing his profits from energy sales. On the other hand, the distribution system operator aims at minimizing the payments incurred in attending the network demand. The interaction between these two agents gives rise to a bi-level programming problem. The equivalent model to account for optimal location, pricing and sizing of DG, that accomplishes the expectative of both agents, corresponds to a mixed integer nonlinear programming problem which is solved by means of a specialized genetic algorithm. The methodology is tested on an 85-bus distribution system, showing satisfactory results.

Keywords : distributed generation; genetic algorithms; optimization; bi-level programming.
