Project Overview

案例概述

The Yunshan Graphite Mine in Luobei County, Hegang City, is located in Hegang City, Heilongjiang Province. The Yunshan Graphite Mine in Luobei County is situated within Yunshan Town, Luobei County, Hegang City, Heilongjiang Province. The mine has advanced graphite processing technology and complete facilities, enjoying unique advantages in graphite production and transportation. It is the graphite mine with the largest reserves in Asia.

鹤岗市萝北县云山石墨矿区位于黑龙江省鹤岗市萝北县云山镇内，矿区石墨加工技术先进、设施完善，在石墨生产和运输方面具备得天独厚的优势，是亚洲石墨储量第一的石墨矿。

The heating system adopts a distributed multi-energy complementary energy storage type three-terminal integrated multi-feedback smart heating system. It thoroughly implements the application of new technologies such as energy transformation and upgrading for heating, smart mines, and mining Internet of Things. The project was initiated in November 2022.

供暖采用分布式多能互补储能型三端一体化多重反馈智慧供热系统，深入贯彻供暖能源转型升级、智慧矿山、矿业物联网等新技术运用，项目于2022年11月启动。

After the project was put into operation, the following achievements were made: 1) Responding to government policy requirements: On March 30, 2022, the provincial government issued the "Comprehensive Work Implementation Plan for Energy Conservation and Emission Reduction in Heilongjiang Province during the 14th Five-Year Plan Period", which proposed: to promote the pilot demonstration of distributed "new energy + energy storage" microgrids, accelerate the intelligent development of coal mines, and achieve smart heating through the real-time integration and interaction of heating data on the smart big data cloud platform, creating a demonstration benchmark for smart enterprises and smart mining areas. 2) Reducing heating operation costs: Under the original heating method, the temperature was maintained at the same level throughout the day, and heating could not be adjusted according to the actual heat demand, resulting in significant waste of energy and costs. After the transformation, heating can be adjusted according to actual heat demand, achieving "energy storage as needed and energy supply as needed", and reaching the optimal balance point between energy conservation and cost reduction.

项目运行后取得两项核心成果：一是响应政府政策要求，契合2022年3月30日黑龙江省发布的《黑龙江省“十四五”节能减排综合工作实施方案》，推进分布式“新能源+储能”微电网试点示范，加快煤矿智能化发展，通过智慧大数据云平台实现供暖数据实时融合与交互，打造智慧企业、智慧矿区示范标杆；二是降低供暖运行费用，原供暖方式全天恒温运行，无法适配用热需求，造成能源与费用浪费，改造后实现“按需蓄能、按需供能”，达成节能与节费的最优平衡。

Project Outcome

项目成果

1. Environmental benefits: Under the environmental pressure of reforming the electricity pricing system and achieving China's "dual carbon" goals, the use of clean energy for heating has received great attention, and a series of policies have been introduced, such as the "Notice of the National Energy Administration on Adapting to Local Conditions for Renewable Energy Heating" on January 27, 2021. The document points out that we will adhere to pilot projects first, encourage the construction of local power grids and microgrids with clean energy as the main body, and support the use of wind power, photovoltaics, energy storage, and microgrids for heating in northern regions.

环境效益：在电力价格体制改革与“双碳”目标的环保压力下，清洁能源供暖备受重视，国家出台多项支持政策，如2021年1月27日《国家能源局关于因地制宜做好可再生能源供暖工作的通知》，明确试点先行，鼓励建设以清洁能源为主体的局域电网和微电网，支持北方地区采用风电、光伏、储能和微电网方式取暖。

2. Energy saving and emission reduction (reduction of pollutants): In order to achieve the action plan of peaking carbon emissions before 2030, China has put forward higher standards and stricter goals for multiple high energy consuming areas. Among the "Ten Actions for Peaking Carbon Emissions", there is the "Carbon Peaking Action for Urban and Rural Construction", calling on the whole country to promote the green and low-carbon transformation of urban and rural construction. The system was put into operation for heating in the 2022 heating season. After the project was completed, it greatly reduced the emissions of pollutants in the atmosphere, saved about 648 tons of standard coal per heating season, reduced about 1615.14 tons of carbon emissions per heating season, generated about 440.64 tons of dust, 48.6 tons of sulfides, and 24.3 tons of nitrogen oxides.

节能减排量（污染物减少量）：为落实2030年前碳达峰行动方案，我国推进城乡建设绿色低碳转型。该系统于2022年供暖季投入使用，建成后大幅降低大气污染物排放，每个供暖季可节约标准煤约648吨，减少碳排放量约1615.14吨、粉尘约440.64吨、硫化物约48.6吨、氮氧化物约24.3吨。

3. Social benefits: At present, China's coal industry is in a critical period of deepening reform. The country has successively issued guiding policies such as "Made in China 2025", "Guiding Opinions on Accelerating the Intelligent Development of Coal Mines", "Digital Longjiang" Development Plan (2019-2025), "Technical Regulations for Intelligent Heating in Heilongjiang Province", etc. On February 25, 2020, eight ministries and commissions of the country jointly formulated the "Guiding Opinions on Accelerating the Intelligent Development of Coal Mines", which will promote the deep integration of modern automation, informatization, intelligent technology and advanced manufacturing technology with coal mining technology under the joint promotion of continuous policy support and continuous updating and breakthroughs of information technology. The successful operation of the project is of great significance for coal enterprises to achieve "intelligent" transformation, and the use of heat storage (cold storage) Technology combines big data and new Internet technology, Enhance the intelligent control and regulation capability of coal mine heating systems. It is a smart heating technology application vigorously promoted in Heilongjiang Province in recent years.

社会效益：我国煤炭行业正处于深化改革关键期，国家出台多项指导性政策推动煤矿智能化发展。项目成功投运对煤炭企业“智慧”转型意义重大，储热（蓄冷）技术结合大数据、互联网新技术，提升煤矿供热系统智慧控制调节能力，是黑龙江省近年大力推广的智慧供热技术应用。

4. Economic benefits: Explore the establishment of a renewable energy heating investment and operation model that conforms to market-oriented principles. Encourage local governments to actively support renewable energy heating projects. But with the growth of installed capacity of clean energy generation (such as wind power) in China, the issue of wind power consumption cannot be ignored due to the limitations of the power grid's transmission and reception capacity. Thermal storage (cold storage) technology plays a significant role in both the electric and thermal fields. The power regulation of valley electric solid thermal storage heating is flexible and variable, which can provide heating services, balance the peak valley difference of the power grid, increase electricity load, play peak shaving characteristics, improve the utilization rate of existing power facilities, and avoid energy waste.

经济效益：项目探索市场化可再生能源供暖投资运营模式，储热（蓄冷）技术可消纳风电等清洁能源，平衡电网峰谷差值，增加用电负荷，发挥调峰特性，提高既有电力设施利用率，避免能源浪费，缓解电网接纳压力。
