Abstract
The electricity sector has evolved over time and with these changes AMI systems have emerged as an important part of the optimal operation of a smart grid. In this sense, information management systems are beginning to gain importance within AMI systems, so the following article presents a state of the art focused on the role played by Independent Information Management Agents (GIDI) in Colombian electricity distribution. network. This document is based on different international experiences that allow gathering information on the guidelines under which these aggregating agents are governed, and then apply this knowledge to the current Colombian case. Finally, the collected information is analyzed and the applicability to the Colombian electrical system is evaluated.

Resumen
El sector eléctrico ha evolucionado con el tiempo y con estos cambios los sistemas AMI se han convertido en una parte importante del funcionamiento óptimo de una red inteligente. En este sentido, los sistemas de gestión de la información empiezan a cobrar importancia dentro de los sistemas AMI, por lo que el siguiente artículo presenta un estado del arte enfocado en el papel que juegan los Agentes Independientes de Gestión de la Información (GIDI) en la distribución eléctrica colombiana. la red. Este documento se basa en diferentes experiencias internacionales que permiten recabar información sobre los lineamientos bajo los cuales se rigen estos agentes agregadores, para luego aplicar este conocimiento al caso colombiano actual. Finalmente, se analiza la información recopilada y se evalúa la aplicabilidad al sistema eléctrico colombiano.

1. Introduction
The electrical system has established itself as an important pillar in the evolution and development of humanity, to the point of being considered the main engine of world economic growth [1]. Different changes such as the fourth industrial revolution, the increase in energy demand, climate change, the insertion of consumers as an active part of the electricity system, the progressive increase in distributed generation sources or other factors, have forced networks to be coupled electricity to the characteristics of the 21st century, so that it can provide an affordable, effective, clean, reliable and efficient electricity service.
In this way, the concept of intelligent network or Smart Grid arises, considering it the network of the 21st century, where technologies, hardware, software or enabling practices are combined that together give way to a more reliable, versatile, secure and accommodating network. , resistant, that is, more useful for consumers [2]. Being the Advanced Metering Infrastructure (AMI) a clear example of these modernizing technologies, which allows bidirectional communication with the users of the electrical energy service, which integrates hardware (advanced meters, measurement management centers, routers, concentrators, antennas , among others), software and architectures and communications networks, which allow the operation of the infrastructure and the management of the data of the electrical energy distribution system and measurement systems” [3] .
Along with this new infrastructure, new agents arise within the energy sector called aggregators, which in the Colombian case are known as GIDI agents (Independent Information Managers), therefore a search for information about these agents is proposed at the international level in such a way that a state of the art of the same is established and the different global experiences can be compared with the Colombian case.
2. State Of The Art
This section presents the results obtained from the development of the phases proposed in the previous section in such a way that once said methodology has been carried out, the state of the art proposed below can be established, which is divided into four sections, in the first place the information referring to the insertion potential of the aggregators in the energy market is classified, in second place It will be organized from the market architectures, then the information will be classified around the different forms of application of the aggregators in different countries of the world and finally rhe advances related to the implementation of advanced measurement infrastructure are presented, so that international experiences can be compared with the Colombian case.
- The Potential To Introduce Aggregating Agents To Different Sectors
The different advances in smart grid infrastructure technologies, information, and communication worldwide, as well as the deregulation of the electricity market, have given way to innovations on the side demand response, emerging a new type of energy service provider, which is known as aggregators [1].
These aggregators correspond to a new actor in the electricity market and its definition and applicability although it varies depending on the international context in which it has been applied, generally refers to an organization that may be independent or a participant in the existing market and acts as mediators between consumers and markets, within which the suppliers of distributed energy resources are involved (including the demand response, distributed generation, and energy storage), as well as the participants of the electricity system that wish to exploit these services [1][2][3][4][5].
In this sense, aggregators can operate in the framework of different scenarios that allow the exposure of end-users to the electricity markets efficiently, these application areas are shown in table 1.
Table I. The Potential To Introduce Aggregating Agents To Different Sectors.
Customer segments | Scope | |
Description | References | |
Smart home | In the household sector, the potential to introduce the new agents of the energy market is given thanks to the automation of homes and digitalization, allowing that energy supply and demand can be matched almost in real-time, enabling the integration into the network products that can help optimize energy consumption, such as smart meters, thermostats, heating and cooling devices. | [6]–[10] |
Smart mobility | In the transport sector, the potential is focused on the advancement in the implementation of electric vehicles in the market, which means that car batteries could be integrated in the grid as a storage facility for surplus energy and become a source of energy supply when the car is not in use. | [11]–[16] |
Smart utilities | In an intelligent network where there is a high insertion of DERs, the services provided by the aggregators help reduce the operating costs of the system, thereby reducing market prices. In addition, the aggregating agents that group DERs to participate as a virtual power plant (VPP) in the energy markets, can provide a balancing service in electricity markets in real-time in a small amount but faster than large, centralized generators | [17]–[21] |
Public lighting | In this sector, the potential of aggregators focuses on being able to adjust the energy behavior within the public lighting system, in such a way that the flexibility of the energy footprint of the system (the difference between the maximum and minimum energy consumption), can be used to reduce costs and increase revenue in other settings. | [22]–[25] |
Smart storage | Aggregators could reduce the disparity between private and system value by financially incentivizing consumers to relinquish control of their storage resources to use them more efficiently for the benefit of a larger electricity system. | [26] [27] [28] [29] [30] |
