How to manage intelligent microgrid

With the continuous optimization of energy structure and the rapid development of renewable energy, Smart Microgrid, as an important part of new energy system, is getting more and more attention. Smart microgrid is a miniaturized smart grid system, which can realize the local production, storage and consumption of energy, and flexibly interact with the main grid, thus improving energy utilization efficiency, enhancing power supply reliability and realizing green and low-carbon development.

Effective management of intelligent microgrid is the key to its stable operation and efficient utilization. To realize scientific management, we must start from the following aspects:
　　irst of all, building an intelligent management system is the core. Intelligent microgrid usually integrates distributed energy (such as solar energy and wind energy), energy storage devices, load management equipment and intelligent control systems. Through the advanced information and communication technology (ICT) and artificial intelligence algorithm, the intelligent management system can monitor the energy flow in the microgrid in real time, predict the demand for power generation and consumption, and make the optimal dispatching decision. For example, energy storage batteries are given priority in power supply at peak hours, and they are automatically charged at low hours, so as to maximize the utilization of energy.

Secondly, optimizing energy dispatching strategy is the key to improve efficiency. In the environment of multi-energy coupling, how to rationally allocate all kinds of energy resources is an important challenge for managers. The energy dispatching system based on big data analysis and machine learning can dynamically adjust the energy distribution scheme according to historical data and real-time status to ensure the stability and economy of power supply. In addition, the introduction of smart contract and blockchain technology also provides a transparent and safe platform for energy trading, which is helpful to realize "peer-to-peer" energy trading.
　　Thirdly, strengthening safety and reliability management can not be ignored. Because microgrid systems are usually used in hospitals, schools, industrial parks and other places that require high power supply, they must have strong self-healing ability and anti-risk ability. By deploying intelligent protection device and remote monitoring system, managers can grasp the running state of the system in real time, find and isolate the fault area in time, and ensure the continuous operation of the whole microgrid system.

Finally, promoting user participation and collaborative management is also the development trend of smart microgrid. By establishing an energy management platform at the user end, users are encouraged to participate in demand response, and the "Prosumer" mode is realized. Users can not only adjust their electricity consumption behavior independently, but also feed back excess electricity to the microgrid, forming a benign interaction mechanism.

In a word, the management of intelligent microgrid is a systematic project, involving many factors such as technology, policy, market and users. Only by constantly improving the management mechanism and integrating advanced scientific and technological means can we really give full play to the advantages of intelligent microgrid and provide strong support for building a clean, efficient and intelligent modern energy system.
