On August 17, the China-Finnish Energy Cooperation Demonstration Project-Guangzhou Nansha's "Multi-One" Micro-Energy Network Demonstration Project was completed and put into operation in Guangzhou.

This is the first successful demonstration project of Zhongfen Energy Cooperation to achieve complementary advantages of the energy industry of China and Finn. Promote the improvement of energy utilization efficiency and help the development of low -carbon new technologies, new models, and new formats.

According to reports, the project was conducted in depth of the three major areas of solid oxide fuel batteries, solar heat collecting systems and base rock energy storage systems around the Guangzhou Power Supply Bureau and Finnish enterprises. , Rock, Burning, thermal, Reserve, and Lotus ", a model demonstration project of micro -energy network, provides a copy -available technology solution and business application model for the efficient utilization of renewable energy and comprehensive energy optimization of the smart park.

Innovative technology Explore the efficiency of energy utilization to the international advanced level

Guangzhou Nansha's "Multi-One" Micro-Energy Network Demonstration Project was selected as the first batch of China-Finland Energy Cooperation Demonstration Projects in January 2019. It has been built in China with the largest single-group capacity of 60 kilowatts of oxide fuel cells and achieved domestic in China. The first set of high -efficiency solar heat collecting systems in distributed energy supply and the application of the first domestic base rock energy storage system in the domestic energy storage system.

What makes people shine is that the 60 -kilowatt -solid oxide fuel cells constructed by the project have an international advanced level, and the efficiency of power generation alone is more than 30%higher than that of traditional coal -fired generators. "The battery system can choose hydrogen, natural gas, biogas, etc. as fuel, and use fuel to choose diversity to effectively improve the power supply reliability of the energy supply system to deal with extreme weather and emergencies." Yang Bo, head of the Hydrogen Energy Research Center of the Guangzhou Power Supply Bureau, said This is also the first time in China that the integration of fuel cells is applied to a distributed energy supply system, which can effectively help the transformation of low -carbon energy in the Greater Bay Area.

The project has also built an internationally -leading high -efficiency solar heat -collecting system, maximizing the use of endless and inexhaustible solar energy. The heat conversion efficiency is as high as 52%, which is 30%higher than domestic similar products. This system covers a small area and has a small carbon reduction effect of the same area. It is suitable for low -carbon transformation in areas with relatively tight land use.

How to realize the flexible application of energy storage and thermal energy for cross seasons has always been a hot research issue in the field of new energy consumption. The project combines the geological characteristics of the Nansha in Guangzhou, and the first domestic stasis layer is used to build the first domestic base rock energy storage system to build the first -season energy storage. "The heat energy of the southern summer can be used to refrigerate. Spring and autumn excess thermal energy can be stored across seasonal storage through the base rock energy storage system, which is released when it is cold in winter. The maximum hot power of the system is 100 kilowatts, which can meet the hot bath needs of more than 200 people at the same time. "Yang Bo said.

Innovate and enrich the application scenario smart energy to help the low -carbon transformation of the Guangdong -Hong Kong -Macao Greater Bay Area

The efficient collaborative use of a variety of energy is another highlight of the project. The Guangzhou Power Supply Bureau has carried out a large number of research work in terms of project integration and localization of projects, and designed intelligent and efficient system integration solutions. The system comprehensive efficiency has reached more than 80%.

On the one hand, the project is based on the efficient utilization of clean energy such as photovoltaic and light heat to effectively reduce the consumption of fossil energy in the park; on the other hand, through multiple energy complement, the entire system has high energy comprehensive utilization efficiency, and uses the smart energy management system guidance to guide the guidance of the smart energy management system. Running makes energy efficiency and economics reaching optimal. By constructing a multi -energy complementary micro -energy network, the organic interaction of "source -network -lotus -storage" can be achieved. It can not only conduct local elimination of distributed energy and balanced on the spot. Parks' anti -disaster protection capabilities and power supply capacity.

This year, in the face of the "hot to turning" sauna sky in the south, the urban grid has also undergone great pressure while driving countless refrigeration equipment. In response to the characteristics of strong solar radiation, high temperature, and long light time of 6-8 months each year, the Guangzhou Power Supply Bureau designed and verified the optical heat innovation application scenario model. In a new application scenario, the collecting heat can produce air -conditioning through lithium bromide refrigeration units, achieving the "heat collection+refrigeration" effect. If the "heat collection+refrigeration" mode is promoted at 10%air -conditioning load in Guangzhou, 400,000 tons of carbon emissions can be reduced each year, which can achieve lower carbon, energy saving, and more environmentally friendly results, and help achieve dual carbon targets.

It is understood that the project is equipped with photovoltaic power generation system, battery energy storage system, lithium bromide refrigeration units, and two -way charging piles of electric vehicles. The use of steps to meet the diversified energy needs of users in the park.

"This project has played a role in energy conservation and emission reduction through the comprehensive utilization of a variety of energy. It is expected that the project park can reduce carbon 200 tons per year, which is equivalent to 10,000 trees. This model is also suitable for hotels, hospitals, industrial parks and islands. Promoting and application of other regional areas. If this project is promoted to 20%of the middle industrial parks in Guangzhou, 40,000 tons of carbon emissions can be reduced each year, and the market prospects are very broad. "Talking about future promotion and application prospects, the Guangzhou Power Supply Bureau is planned and developed Wang Ke, the head of the department. Guangzhou Nansha's "Multi -One" Micro -Energy Network Demonstration Project is the efficient utilization and comprehensive energy optimization of renewable energy in the smart park, and provides a copy and promotion technical solution and business application model. Essence

In recent years, Southern Power Grid Corporation has continued to promote the development and utilization of clean energy, promote the construction of a diversified energy supply system, change the reform of energy consumption, and promote low -carbon transformation of energy supply side. Guangzhou Nansha's "Multi -One" micro -energy network demonstration project will be completed and put into operation. It will be an innovative window for the Guangzhou Power Supply Bureau's foreign exchange and cooperation. It will have an important milestone significance under the new pattern of low -carbon transformation.

In the future, the Guangzhou Power Supply Bureau will actively explore more intelligent solutions for low -carbon transformation of energy, and fully integrate into the green and low -carbon development of the Guangdong -Hong Kong -Macao Greater Bay Area, helping to achieve carbon peaks and carbon neutrality.
