adopts transport layer security for establishing secure channels
between a VTN and a VEN for communication. In high-security mode, the standard adopts an open architecture for, and
will not restrict itself to, some specific or proprietary technologies. Figure 2 summarizes the smart grid standards road map
involved in ADR. All these protocols play an important role in
the standards road map of the main organizations and countries that participate in strategies related to energy.
The OpenADR standard protocol simplifies the management of DR, making the process easier than those implemented
in the IEC and IEEE protocols. The functionalities of the IEC
and IEEE protocols are wider-ranging and more specific than
OpenADR protocols. However, the OpenADR functionalities may involve several IEC or IEEE functionalities because
OpenADR has a high level of encapsulation. The question is
whether the congestion management functionality provided by
OpenADR is enough to solve the problem of ADR, following the Occam's razor principle that the simplest explanation
is often the best one.

The Flexibility4Chile Project
The Flexibility4Chile project is intended to test the following:
✔ the connectivity between the DSO and customers (by
means of aggregators or directly) based on standard
protocols, such as OpenADR from OASIS

✔ the benefits of these initiatives for congestion manage-

ment and network quality
✔ new strategies, use cases, and technical requirements
for DR and DER integration using smart grid assets,
such as smart inverters, energy storage, and other controllable loads.
The project was developed in two stages. During the first,
the project was deployed at the Enel smart grid building,
shown in Figure 3, a modern structure located in the Huechuraba Business Park in Santiago de Chile, Chile. This building is an attempt at a complete demonstration of new smart
grid technologies, showing the potential of smart meters,
renewable energy and EV grid integration, and flexibility
programs. The building has photovoltaic (PV) generation,
an electric recharging point, and a whole set of controllable
loads, such as the heating, ventilation, and air-conditioning
and lighting systems.
During the second stage, the project tested the OpenADR
protocol at an alternative location at the Savona campus of
the University of Genoa, Italy. The project was a successful collaboration between enterprises and universities to
develop a proof of concept (PoC) in the context defined in
Figure 4 but without TSO involvement. The hierarchy of
the PoC involves Enel as a DSO, funding organization, and
project coordinator and the Electric Power Research Institute as the technology and strategy adviser. The University
of Seville, Spain, developed the DR management system
(DRMS) based on the capacity-bidding program (CBP).
The Maps Group (a technology company from the north of
Italy) developed and deployed the aggregator platform to
provide FSs. The aggregator controls the customers' facilities, in this case, the Living Lab deployed at the Savona
campus. The Living Lab is a real microgrid test bed in an
experimental smart grid environment where innovation initiatives can be tested.
The main objective is the generation of new products, services, infrastructure, and knowledge to meet society's needs.
The objective of the second stage is to show the viability of
