Cargos de respaldo por uso de la red eléctrica en el costo unitario de energía distribuida: desafíos y oportunidades para la planificación.

With the technological advance in electricity generation techniques and the prevailing need for sustainable development of countries, the massive use of alternative energies has been in force for the last 15 years, with clear goals towards 2020 for sustainable development. At the regulatory level, Colombia cannot be left behind in the regulation, and progress has already been made on the subject with law 1715 of 2014 and several decrees of incentives in the promotion of renewable energies. The objective of this paper is to show the state of the art on the way in which the net balance and residential energy self-consumption by DER is handled by several tax regulations in different countries of Europe; moreover, it will also go into detail about the advantages offered by using a selected methodology to consider fair charges of support for the use of the electrical network by generators distributed from photovoltaic solar energy, all this as a contribution to advances already made in this field. This is provided from a network planning approach, in which a long-term methodology is selected that efficiently integrates the distributed generation into the interconnected system and allows transition periods in its implementation to avoid disruption of network operators (ORs). Likewise, this analysis is supported by the simulated operation of a system with DER together with the changes in load flows due to decongestion and surplus injection that the electric system has in the scenario of massive use of these resources.
