スマート マイクログリッドの開発と実装は、いくつかの主要なテクノロジーに依存しています。まず、新エネルギー・再生可能エネルギーの発電技術の活用が不可欠です。現在、スマート マイクログリッドは主に、太陽光発電や風力発電、水素、天然ガス、バイオガスなどのさまざまな再生可能エネルギー源に依存しています。これらの成熟した発電技術により、多様かつ持続可能なエネルギー供給が可能になります。

Secondly, energy storage plays a crucial role in microgrids. It helps to balance the intermittent nature of renewable energy sources by providing peak shaving and valley filling capabilities. Several energy storage technologies are currently being used, including battery energy storage, flywheel energy storage, superconducting magnetic energy storage, and supercapacitor energy storage. While lead-acid batteries are currently the most mature energy storage technology, they face issues such as short lifespan and lead pollution. However, the marketization of graphene batteries, which offer high energy, low cost, and high-quality performance, holds great promise for the future of energy storage in smart microgrids.

第三に、スマート マイクログリッドにおけるエネルギーの最適化と配電は、従来の電力網とは異なります。スマートマイクログリッドは、水平型複数エネルギー補完最適化配電技術を採用しています。これにより、さまざまなエネルギー管理システムの効率的な利用が可能になり、熱、電気、冷気の出力が実現されます。さらに、光/電気、熱/冷気、風力/電気、直接/AC エネルギー交換など、異なる電源間の直接補完代替が可能になります。ソース-ストレージ-負荷リンクにおけるエネルギーの階層的かつ秩序あるディスパッチにより、最適なエネルギー利用効率が保証されます。

Lastly, smart microgrids require effective protection and control technologies. With multiple power sources and loads in operation, adjustments and control through the energy storage system or the external power grid are necessary to accommodate load changes and power supply fluctuations. The microgrid control center handles the regulation, switching, and control of these power supplies. It monitors the power parameters, switching status, power quality, and energy parameters of each new energy power generation system, energy storage system, and load. Additionally, the microgrid control center focuses on energy saving and improving power quality to enhance the overall performance of the smart microgrid.

The rapid development of smart microgrids is reshaping the traditional power grid landscape. These microgrids establish an exchange of energy with the larger power grid, serving as backups for each other. This active distribution network enhances the reliability of power supply by integrating the capabilities of distributed energy resources. Smart microgrids offer great potential in reducing energy consumption, improving power system reliability, and enhancing flexibility. As a result, microgrid technology has gained significant attention and is seen as a new direction for power system reform. The marketization process of key equipment in smart microgrids will accelerate the advancement and performance of these technologies.
