The benefits of implementing Demand Response (DR) programs in large consumers have been widely documented. However, it is still necessary to explore in more detail the impacts of the implementation of these programs in residential users on the benefits of the distribution system operators. In this paper, we determine the effects of Demand Response (DR) on the reconfiguration of a distribution system considering the consumption characteristics of residential users in Colombia. For this purpose, the demand curve of a typical residential user was constructed for Bogotá D.C., and measurements were taken to estimate the participation of this user in a DR program. In addition, an algorithm based on Particle Swarm Optimization is used as a solution strategy for the reconfiguration problem. The results show that a distribution system reconfiguration could significantly increase the revenues obtained by a Network Operator. However, it is shown that the reduction of energy losses obtained from the DR would not provide sufficient incentives for them to promote the participation of residential users in this kind of programs.

In this paper, a conceptual model for technical microgrids conception applied to a case study in Colombia is presented. The model considers aspects as: medium voltage electrical system topology setting, preselection of generation technologies, electrical demand prioritization, generators location employing the voltage Stability Index (SI), operation strategies and capacity sizing of distributed generators, components modeling and the evaluation of microgrid performance in aspects as voltage profiles and optimal power management. The conceptual model developed was applied in a case study for the Valle del Cauca region, Colombia, which presents urban and agroindustry areas suitable for the research requirements. For the microgrid steady-state performance evaluation, the computational tool of power systems analysis Neplan® was used. [ABSTRACT FROM AUTHOR]

This paper presents the results of the study that evaluates the incorporation of FACTS technologies in the expansion planning process of the Colombian National Transmission System (NTS). The application methodology uses as starting point the optimization of the exploitation of the existing system by increasing its transmission capacity and it is based on steady-state analysis. This paper presents the results of the feasibility study for a wide application of FACTS systems in the Colombian Transmission System for improving transmission capabilities and reliability and security levels after year 2005.

This paper present the result obtained in the research related the eastern municipalities of Antioquia with special focus in the municipality of San Carlos about the transfer of the power sector delivered to them during the years between 2000-20012, for concept to the intensive use of natural resources of the region (water and earth) that the power company make in the regions with hydropower settlements. In conclusions, we observed a compensatory inequality in the municipalities studied due the criterion for delivering predominates transfers is the installed capacity and the watershed criterion above the reservoir criterion which is more closely related to the consumption of land, and is the most visible contribution of natural capital of the municipalities in hydroelectric settlements element.
