information assets (for example,
information/content, applications and business
processes), knowledge assets and human assets and
seeks to integrate and aggregate information from
multiple cross-enterprise applications.
Business Process Management: The systems
included in this category are the set of tools,
technologies, techniques and methods for the
identification, modelling, analysis, execution,
control and improvement automated business
processes.
Enterprise Service Bus: To complement the
interoperability of information systems at the tactical
level a platform of Enterprise Service Bus must be
adopted, to share information between the processes
of transmission, distribution, generation and national
control center. An ESB is an infrastructure normally
based on SOA whose purpose is to provide
interoperability (connectivity, data mapping and
routing) combined with some additional services
such as security and monitoring.
4.4 Business Systems
Information systems in this section are those that
allow to identify, retrieve, and analyze large
volumes of information and provide assessments and
historical, current and predictive studies as the main
support for strategic decision making through a
formal and disciplined process of exploitation of
information to monitor the company's strategies and
generate new knowledge. Business intelligence is a
matter not only of technology, it is necessary that the
company deploys a business intelligence strategy
that is executed by the BICs and this requires an
infrastructure of software and hardware as well as
organization and models.
4.5 Standards
The standards and best practice for development and
operation of the systems.
Regulation and Standardization: There should
be a governing model that covers the requirements
of the company to comply with all laws, rules and
national and international regulations. There are
information systems usually associated with the
handling of such information.
Security and Risk Management: A
comprehensive approach to security and risks
management is needed in the utility; today we have
found security issues practically in every component
in the architecture. Normally there is an
infrastructure that facilitates the management and
verification of these aspects and the strengthening of
vulnerabilities. The security strategy should include
policies, procedures and adherence to international
standards and to keep up to date on issues in areas
where there is still no definition.
Architecture Governance: The architecture of
information systems is important but more important
to have the governance necessary to allow the
architecture is feasible and successful, that is, having
the definition of responsibilities, principles, policies
and procedures establish a process cycle life of the
architecture. TOGAF (The Open Group Architecture
Framework) should be considered to define this
model.
5 CONCLUSIONS
The Smart Grid strategy calls for enterprise
architecture. Smart Grid architecture will be a
composition of many system architectures and
subsystem, thus will allow the maximum flexibility
during the implementation, but at the same time, it
will demand a high capacity of integration of the
new systems with legacy systems. The proposed
architecture provides a single, consistent view of
information of the main process and includes
automation and control systems at all levels, from
plants and substations control systems to corporative
intelligent centre, including the operating centre and
the energy trading system. The architecture
considers the adoption of standards such as IEC
61968 and IEC 61970, which define the common
information model (CIM), the IEC 61850 for
substation automation, IEC 62351 for security
information, COBIT and ITIL for IT governance.
The enterprise architecture is capable of providing
timely, secure, reliable information exchange among
various processes in the system and is also scalable.
