Cities of the Future: Songdo, South Korea – Energy

Songdo International Business District's information technology network manages energy use in every building, making the city very "green." Episode 7 in the series.

Transcript:

As populations expand and economies grow, people are consuming more non-renewable energy sources than ever. The race is on to make cities radically more energy efficient.

Songdo, South Korea, a new city built entirely from scratch, is on the forefront.

In Songdo, a revolutionary information technology network manages energy use in every building.

Jean-Louis Massaut, Director, Cisco Services Korea: The network that we deploy here is actually connecting all of the components in the city, all of the building subsystems together, so that we can bring energy savings.

Scott Summers, Vice President, Gale International:We're improving the efficiencies of each of the buildings. Our windows have low U value that reduces the amount of sunlight coming in and keeps the energy of the heat or cooling inside the building. Another component to reduce energy consumption (is) we light up the buildings with LED lights.

Peter Lee,Sustainable Design Specialist, Cosentini Korea: On the system level, we introduced water-cooled air conditioning system; it has never been applied to any Korean project before. We also have central home network system through which you can control your electricity use to reduce the dependence on the energy.

These innovations are helping reduce energy consumption in each building by 30 percent.  The city is also tapping into renewable natural resources.

Lee Jong-Cheol, Commissioner, Incheon Free Economic Zone: Sunlight, solar energy, windforce energy are being currently used to operate the city. Even human waste isn't simply disposed of. It is processed through a recycling system and a co-generation plant producing necessary energy.

Scott Summers: We have a co-generation facility that uses natural gas to power electricity. And the waste heat is in the form of hot water, and so we use that waste heat to run up our buildings and provide heating for our residential units.

By 2040, worldwide electricity demand is projected to be 80 percent higher than it is today. Songdo is a model for cities trying to keep pace.

News release from Burns & McDonnell:

Burns & McDonnell dedicates new Smart Grid Laboratory

FOR IMMEDIATE RELEASE: January 27, 2012

KANSAS CITY, Mo. — Burns & McDonnell has significantly expanded and upgraded its Smart Grid Laboratory as a result of a move into a new larger testing and development facility equipped with more than $1 million in state-of-the-art diagnostics and testing equipment. The new facility was formally dedicated during a Jan. 27 open house for employee-owners and clients. The new testing facility is now open and available for the exclusive use of Burns & McDonnell clients.

Located in a 600-square-foot space within the Burns & McDonnell World Headquarters, the lab incorporates the technologies clients are using to modernize the power grid. These include:

• IEC 61850 - GOOSE, MMS, and Sampled Values messaging for both control and process bus implementations
• DNP 3.0
• Protective relaying over packet networks
• Network technologies including SONET, Ethernet, IP, and MPLS
• Fiber and wireless communications technologies
• Substation automation logic controllers
• SCADA Remote Terminals
• Data Concentrators
• Fault Recorders
• Metering equipment measuring power quality and harmonics
• GPS and IEEE 1588 time synchronization.

The laboratory is intended to demonstrate how advanced information technologies can be integrated with power delivery equipment as the industry moves toward highly automated, "self-healing" distribution systems. The lab allows Burns & McDonnell engineers to work with clients to configure and test solutions during design and installation, therefore improving project success and speed of deployment.

The Burns & McDonnell Smart Grid Laboratory was first built in 2007 as testing facility for select clients who were interested in demonstrating interoperability of software, two-way communications equipment and other automation equipment in preparation for deployments of Smart Grid projects. In addition to the latest technologies and devices, the lab is capable of simulating two complete substations and varying power conditions. It has the equipment many utilities have been deploying, enabling testing of interoperability between multiple vendors and vintages of equipment.

Equipment and systems in the lab can test advanced substation and distribution feeder automation using IEC 61850 and DNP 3.0 testing applications between multiple vendors and relay types. It can also stage demonstrations of high speed tripping using GOOSE messaging, HMI interoperability, substation visualization and automation systems. Communications with deployment of Ethernet, IP, and MPLS technology can focus on a converged networking platform for security, automation and protection.

Another issue facing Smart Grid deployment is interoperability of legacy and advanced equipment. By demonstrating how legacy and advanced equipment can be integrated together in a unified design, investments in IED relaying incorporating the latest technologies can be justified. The lab has successfully demonstrated solutions such as tying IEC-61850 to the power line carrier and integrating advanced protection and control systems with legacy equipment using RS-232 and DNP interfaces.

Additionally, security tests can be implemented through firewalls and gateway devices with card access and physical security sharing a converged network. These tests have been helpful in showing how to integrate security into substation design.
