LISINER Poyang Low-Carbon Intelligent Microgrid Project Officially Put into Operation

Against the backdrop of further advancement of the Dual Carbon Strategy, the manufacturing sector is undergoing profound transformation underpinned by green and intelligent development. As an innovative pioneer in the new energy industry, LISINER has recently made a key strategic layout in Poyang, Jiangxi. By developing an industrial-grade low-carbon intelligent microgrid demonstration project, the company injects green momentum into its energy storage system manufacturing base and accelerates the development of new productive forces through innovative practices.

Covering a land area of around 160,000 square meters with a total investment of 230 million yuan, the Poyang Low-Carbon Intelligent Microgrid Project covers the full industrial chain including photovoltaic power generation, intelligent energy storage and flexible power distribution. As an important local green pilot project, Phase I deploys a 2.8MWp rooftop photovoltaic array and is equipped with a 5.4MWh modular energy storage system, forming a compact energy ecosystem featuring coordinated operation of source-grid-load-storage. At the current stage, the project saves approximately 900–1,500 tons of standard coal annually and cuts carbon dioxide emissions by roughly 2,400–3,400 tons per year, equivalent to planting 130,000 trees. This marks an innovation in the energy management model for industrial parks and delivers vital support for the green and intelligent transformation of manufacturing bases.

Overall Advantages of the Solution

• Low Cost & Long Service Life: Adopting innovative DC coupling technology, the whole station loss is ≤5%, efficiency rises by over 4%, and equipment service life exceeds 10 years.

• Standardized Prefabricated Cabin: Integrated all-in-one station with modular design. No transformer capacity expansion or circuit renovation required, enabling rapid deployment and flexible capacity expansion, cutting costs by about 23%.

• Intelligent Monitoring & Control: Self-developed EMS system plus one-stop platform with millisecond-level response, realizing intelligent management and reliable safety protection.

Create a New Paradigm of Scenario-based Smart Energy, Driving Green Transformation from Production Zones to Living Areas

Production Zone: Stabilizer for Manufacturing

① It adopts an integrated DC coupling system to realize black start and seamless switching between grid-connected and off-grid modes. Dynamic voltage compensation technology eliminates harmonic interference and ensures uninterrupted power supply within less than 20ms for precision equipment.

② Based on an intelligent energy management system, it automatically adjusts charging and discharging strategies to tackle concentrated energy consumption of large-scale equipment.

③ A three-tier power guarantee system is established to achieve zero power outages on core production lines throughout the year.

Living Zone: Power Bank for Green Living

① The intelligent DC coupling solution enables flexible capacity ratio adjustment for photovoltaic systems, energy storage and charging piles, featuring convenient installation and maintenance to meet evolving charging demands.

② With intelligent time-of-use power consumption strategies combined with surplus electricity heating systems, the comprehensive energy cost is reduced by approximately 28%.

③ Innovative application of DC power supply technology. Liquid-cooled DC supercharging is deployed with fixed DC bus voltage via DCDC to unlock superior technical performance.

Continuously Exploring the New Track of Energy Storage Innovation to Become a Pioneer of Green Intelligent Microgrids

Integrating four major systems of photovoltaics, energy storage, charging and flexible power distribution, the Poyang Low-Carbon Intelligent Microgrid Demonstration Project forms a full-chain closed loop of self-generation & self-consumption, surplus power storage, intelligent dispatching and emergency support. Supported by the dual-drive model of Manufacturing + Energy, it delivers full-lifecycle services for industrial parks ranging from energy consumption to management. The successful commissioning of the project not only demonstrates the leading edge of LISINER’s intelligent microgrid solutions, but also provides replicable models for the low-carbon transformation of industrial parks.

Moving forward, LISINER will further verify the feasibility of distributed clean energy systems in industrial scenarios, continuously deepen integrated innovation between digital intelligent technologies and energy systems, and roll out more benchmark projects to power the green transition of China’s manufacturing industry.
