The first China-Finland energy cooperation demonstration project was put into operation in Sui

On August 17th, the china-Finland energy cooperation demonstration project - Guangzhou Nansha "multi-in-one" micro-energy network demonstration project put into operation ceremony was held

The staff of Guangdong Guangzhou Power Supply Bureau of China Southern Power Grid is carrying out the inspection of the solar collector system of the "multi-in-one" micro-energy network demonstration project in Nansha

Innovative technology exploration

Energy utilization efficiency has reached the international advanced level

Guangzhou Nansha "multi-in-one" micro-energy network demonstration project was selected as the first batch of China-Finland energy cooperation demonstration projects

What is eye-catching is that the 60-kilowatt solid oxide fuel cell of the project has an international advanced level, and the electrical efficiency alone is more than 30% higher than that of traditional coal-fired generating units

The project has also built an internationally leading high-efficiency solar collector system to maximize the use of solar energy, with a thermal conversion efficiency of up to 52%, which is 30% higher than that of

How to achieve cross-seasonal energy storage and flexible application of thermal energy has always been a hot research issue

Innovation enriches application scenarios

Smart energy contributes to the low-carbon transformation of the Guangdong-Hong Kong-Macao Greater Bay Area

The efficient and collaborative use of multiple energy sources is another highlight

On the one hand, the project is based on the efficient use of clean energy, effectively reducing the consumption of fossil energy in the park; On the other hand, through multi-energy complementarity, the comprehensive utilization efficiency of energy is improved, and the intelligent energy management system is used to guide the operation, so that energy efficiency and economy can be optimized
.
By building a multi-energy complementary micro-energy network and realizing the organic interaction of "source-network-load-storage", it can not only absorb and balance distributed energy in situ, but also exchange energy with the large power grid, which improves the disaster resistance and power supply capacity
of the park.

In view of the characteristics of strong solar radiation, high temperature and long illumination time in the south for 6-8 months a year, Guangzhou Power Supply Bureau designed and verified the innovative application scenario mode of solar thermal, and for the first time in China, the solar collector system was extended to the new application scenario of the cooling mode, and the collected heat energy was generated by the lithium bromide refrigeration unit to produce cold air, achieving the effect
of "heat collection + refrigeration".
If the "heat collection + cooling" model is promoted according to 10% of guangzhou's air conditioning load, carbon emissions
can be reduced by 400,000 tons per year.

It is understood that the project is equipped with photovoltaic power generation systems, battery energy storage systems, lithium bromide refrigeration units, electric vehicle two-way charging piles, etc.
, and has built a multi-energy flow network of cooling, heat, electricity, gas and transportation, which can realize multi-energy interconnection and cascade utilization, and meet the diversified energy needs
of park users.

"Through the comprehensive utilization of multiple energy sources, it is expected that the project park can reduce carbon by 200 tons per year, which is equivalent to planting 10,000 trees
.
" This model is also suitable for promotion and application in areas such as hotels, hospitals, industrial parks and islands, and the market prospects are very broad
.
Wang Ke, head of the Planning and Development Department of Guangzhou Power Supply Bureau, said that the "multi-in-one" micro-energy network demonstration project in Nansha, Guangzhou, provides a replicable and generalizable technical solution and commercial application model
for the efficient utilization of renewable energy and comprehensive energy optimization in smart parks.
