1. Introduction
The Smart Grid (SG) is based on a new vision of the electric grid, which includes the
maximization of the distribution of energy demand, the minimization of losses and the
integration of renewable energy sources on a large scale, as pointed out in [
1
–
3
]. The SG
aims to overcome one of the main limitations of the current electric grid, related to the lack
of integration of novel information and communication technologies.
The current information and communication technologies include those based on the
Internet of Things (IoT), which plays a strategic role in the era of Industry 4.0, as shown
by [
4
–
8
]. The eXtensible Messaging Presence Protocol (XMPP) and the Message Queue
Telemetry Transport (MQTT) are some of the most well-known protocols in this field [
9
–
11
].
The REpresentational State Transfer (REST) is an architectural style defined by Roy Fielding in
his PhD dissertation [
12
]; a web service based on REST is called a RESTful Web Service [
13
].
The RESTful Web Service is a paradigm that can enhance the IoT application scope by making
smart things part of the web [
14
].
The paper proposes a novel solution in the field of the integration of SG and IoT. In
particular, the proposed integration involves IEC 61850, which is an international standard
defining communication protocols for intelligent electronic devices at electrical substa-
tions [
15
,
16
]. The definition of a web platform able to offer to a generic web user a RESTful
interface to IEC 61850 Servers is proposed. The web platform is based on a REST architec-
ture and enables the mapping of IEC 61850 information model into MQTT messages. The
platform is called the
IEC 61850 Web Platform
in the remainder of the paper.
The paper is organized as follows. The next section provides an overview of the current
state-of-the-art research, and highlights the originality of the proposal. Section
3
introduces
the main features of the IEC 61850, focusing on the relevant data model. Section
4
describes
the IEC 61850 Web Platform in detail. Section
5
presents the implementation details of the
prototype realized by the authors. The final section summarizes the main results.
