"Empowering green industrial parks through the combination of microgrids + virtual power plants will make the park greener, safer and more economical to support the system, and make the difficult triangle of the energy industry realize. Recently, Gong Chengming, vice president of Telai New Energy Co., Ltd., who is actively deploying the field of microgrids, said at the Sichuan Green Smart Energy and Distribution Network Charging Network High-quality Conference: "Microgrids are an important carrier for large-scale electric vehicles to integrate into the new power system. ”
Industrial green microgrids are popular with policies
On December 6, the people of Tongchuan City issued the "Implementation Plan for the Comprehensive Work of Energy Conservation and Emission Reduction in Tongchuan City during the 14th Five-Year Plan", pointing out that the development of industrial green microgrids will guide industrial parks to accelerate the development and operation of integrated systems such as distributed photovoltaic, distributed wind power, multiple energy storage, waste heat and pressure utilization, and smart energy management.
Tieling City, Liaoning Province, also mentioned in the "14th Five-Year Plan" comprehensive work plan for energy conservation and emission reduction, the development of industrial green microgrids, support the development and utilization of clean and low-carbon energy in free places, and the construction of distributed clean energy and smart energy systems.
At the same time, the Ministry of Industry and Information Technology has also repeatedly stated that it will strengthen the demonstration of typical application scenarios and organize the selection of typical application scenarios and cases of industrial green microgrids nationwide.
Under the guidance of a series of policies, the green and low-carbon transformation is being further accelerated.
The microgrid moped vehicle-network interaction plays the role of "power sponge".
Microgrid is in the scenario of enterprise parks or charging stations, integrating distributed photovoltaics, electric vehicle charging and discharging, energy storage, wind power, etc., and with the support of large power grids, it becomes a small AC and DC power generation power system, realizing local consumption, local storage, and local balance of new energy power generation, charging with light and wind, realizing the charging of new energy vehicles and new energy electricity, and realizing the efficient interaction of active power distribution, which is a new carrier of the new power system.
The form of microgrid is a very important application scenario for vehicle-to-network interaction, providing scarce flexible resources for new power systems.
For example, through microgrids, V2G can be integrated into the campus microgrid, which can be connected to the grid or off-grid, and can be used for on-site consumption of photovoltaics or peak-to-valley arbitrage. For large power grids, microgrids can solve the problem of charging and discharging. Especially at this stage, the discharge function can be applied and promoted in microgrids. In addition, microgrids generally have energy storage needs, and the batteries of electric vehicles can be turned into energy storage resources that are very important for microgrids to maintain the balance of the power system, realize the efficient interaction of active distribution networks, and are the new carriers of new power systems.
As a leading charging enterprise in China, based on the charging network technology route, the number of charging microgrids it has built is currently in the forefront of China. The "charging microgrid" product released by Telai - special microgrid, which is composed of multiple parts such as micro-grid box transformer, photovoltaic canopy, charging terminal, etc., can absorb 100% of the new energy generated by photovoltaics, and can also stabilize the volatility and disorder of new energy power generation with the help of mobile energy storage of electric vehicle batteries and echelon energy storage resources of retired power batteries. As of June 2023, Telai has invested in the construction and operation of nearly 300 rechargeable microgrids in 75 cities across the country.
As a charging service facility in the industrial park, the microgrid can provide better charging conditions for employees, and improve the reliability and sustainability of electricity consumption in the park by integrating multiple energy resources and balancing supply and demand. Through the virtual power plant with "charging network + microgrid + energy storage network" as the carrier, it can also dispatch the surplus power and energy storage power of the vehicle battery, participate in the frequency regulation and peak regulation of the power grid, and fill the valley, so as to build a new power system, support the development of large-scale new energy vehicles, and realize the charging of new energy vehicles.
