As a world-class manufacturing company, how to intelligently manage the energy in the park to reduce energy and emissions while achieving cost reduction and efficiency, how to respond to the dual-carbon target and use clean energy to create a zero-carbon park, and how to use high technology to realize an integrated platform for efficient management of comprehensive energy has become one of the development priorities of Xinmei in recent years.

Green low-carbon factory management platform

So far in 2019, Huafon's energy storage team has helped Xinmei implement the national "carbon peak, carbon neutral" strategy and explore the intelligent management of integrated energy in the park by applying smart microgrid control technology. The "green low-carbon factory management platform" and microgrid control we provided for Xinmei realize the visualization and intelligent operation of energy system, and the cooperative management of PV system, energy storage system, flexible load and charging pile; using industry-leading algorithms such as PV and load prediction model, temperature-power model and optimization decision model. Combining edge computing, cloud-side collaboration and big data technology, it realizes dynamic and flexible regulation and optimal management of energy equipment; through the use of strategies such as local consumption, AI peak-shaving and valley-filling, demand control and flexible load regulation, with the goal of low carbon, economy, efficiency and safety, it helps the park fully increase the proportion of clean energy consumption, improve energy utilization efficiency, make energy use more reasonable and efficient, and significantly reduce Energy consumption and production costs of enterprises have been significantly reduced.

"The 'green low-carbon factory management platform' provided by Huafon ESS, through intelligent means, scientifically and dynamically adjusts the power consumption of enterprises, greatly reducing the power consumption load during peak periods." The person in charge of Xinmei Electric said, "In the past, when the enterprise was running at full load of the production line, the hourly electricity consumption was about 2,000 degrees; currently, through this platform, the company can save about 600 degrees of electricity per hour on average." In addition, Huafon ESS also helps Xinmei to carry out intelligent "source-grid-load-storage" regulation and provide demand-side response services for the grid. When the grid sends out demand-side response dispatching instructions, the microgrid controller will independently adjust and optimize the operation of the energy storage system and flexible load in the park to meet the dispatching instructions, realizing the interaction between the park load and the grid.

Huafon ESS helps Xinmei Electric's "Zero Carbon Park" project to actively promote a green, low-carbon, efficient and clean development model, achieve optimal management of carbon emissions, and bring about cost reduction and efficiency improvement for the enterprise. In 2020, it achieves carbon dioxide emission reduction of 616.01 tons, 986.21 tons in 2021, and 1425.78 tons in 2022. 920,000 Yuan in 2020, and 1.69 million Yuan in 2021, taking the lead in achieving carbon neutrality.

Huafon ESS Microgrid Solution

What is the technology behind Xinmei Electric's green low-carbon park? -- It is Huafon's intelligent microgrid solution for energy storage.

Microgrid is an electrical interconnection system containing a high percentage of renewable energy, which undertakes the task of using and consuming renewable energy, and interacts with the large grid, which can improve the utilization of renewable energy and improve the economic and environmental benefits while ensuring the safety and stability of the large grid. And at the same time, the construction technology of microgrid also faces many challenges:

1. The micro-sources in the micro-grid are complex and diverse, including wind energy, light energy and other diverse energy sources. Each micro-source has its own unique operation and working mode, and it is difficult to make reasonable real-time optimal scheduling according to the actual changes. The controller needs to have the ability to handle a large number of controllable objects with mixed characteristics.

2. single data decision failure new energy generation has strong uncertainty, time-varying characteristics, then the data such as meteorology and power data coupling decision, turn passive into active, to improve its measurable and controllable ability and security stability, is the key to technology.

3. strong anti-interference ability is required in microgrid power supply is distributed, decision-making and control objects, signal changes quickly, the traditional controller is weak anti-interference ability, reaction, processing, decision-making speed and efficiency can not meet the needs of new energy environment microgrid control.
