scheduling and smart substations, the eco-city’s
power supply reliability, voltage qualified rate and
N-1 pass rate stand at 99.999%, 100% and 100%
respectively, and the overall line loss is reduced by
1.18%, improving energy supply reliability.

The Sino-Singapore Tianjin Eco-City Smart
Grid demonstration project aims to verify new
smart grid technologies, specifications, equipment performance and to test smart grid technologies in a comprehensive way. Its economic
benefits include lower investment costs, reduced
line losses, improved power supply reliability,
lower operation and maintenance costs and
enhanced operating efficiency (Fig. 41). The
project saves 1,074 tonnes of fuel oil and 5,929
tonnes of standard coal equivalent (SCE) per
year and reduces CO 2 emissions by 18,488
tonnes annually.

microgrid project
The project is located at the university campus.
The microgrid comprises one 380 kW solar
photovoltaic
(PV)
system
and
a
2 Â 100 kW/100 kWh energy storage system. It
supplies seven dormitory buildings. The microgrid controls the power distribution system for
the buildings and canteens in Power Distribution
Zone IV at the university, including two energy
storage systems and 32 low voltage power distribution lines. It also communicates with the
power scheduling system. During operation, the
