1. Project summary (background)

Seoul National University is counted every year as the space that uses the most energy in Seoul. However, when the ongoing “Campus Microgrid” project is completed, it is expected that such disgrace can be resolved. Stable and efficient use of power is required to maintain a large campus space and control the amount of unnecessary power used while conducting research and experiments day and night. ‘Microgrid’ is a future energy supply and demand system that will solve the power problem of Seoul National University. It refers to a power grid that generates and consumes electricity in a specific area independently from the existing wide area power system. Seoul National University is the first to be built on a domestic urban campus.

2. Objectives of the project

Development of a customized SNU Campus MG model to provide

• 4 hours islanding operation to critical loads
• 20% peak load reduction and energy cost saving by cell MG model
• Consumer participative energy-saving by IoT based Bigdata platform
• Multi-Microgrid operation with different cell types

3. Current status & results (outcomes)

• Developed as a customized campus microgrid that can be flexibly changed and applied according to customer needs
• Provides customized solutions for the smallest unit of sale by combining IoT-based cell platform and models for each campus building purpose
• Consists of a cell system area that efficiently operates energy and a cloud area that provides various services based on IoT

4. Barriers & obstacles

New roles within the existing energy law & legislation.

5. Lessons learned & best practices

• Through the demonstration project, various information such as power consumption, temperature, humidity, ventilation, etc. of the building is collected and analyzed, and distributed power such as solar and electric vehicles(V2G) and ESS are used together with power supplied from the existing power grid. Plan to reuse electricity during high energy prices
• Reduced electricity bills are reinvested to expand the introduction of new and renewable energy, or plan to use them to increase energy independence through replacement of old facilities such as low-efficiency air conditioners.
• From 2019, when the demonstration project is completed, some buildings, such as the Bio Research Building, can operate independently for 4 hours even if external power supply is cut off due to natural disasters such as earthquakes and typhoons, and 20% of the total electricity bill of Seoul National University can be reduced.
• It is expected to be able to systematically demonstrate the operation system constituting the microgrid, big data analysis, demand response, energy consumption pattern analysis, etc.
