The biggest advantage of applying microgrid to the power system lies in its flexibility. Microgrid can be simply understood as a miniature power grid, where the term "micro" refers to the voltage of the microgrid operating below 10 kilovolts, which means that the overall operating voltage of the microgrid is lower than that of the voltage in the 10 kilovolt distribution lines. The power capacity of the microgrid is also controlled below megawatts. In the process of applying battery energy storage system technology to microgrid, the main approach is to directly connect it to the home power system, achieving direct access to the user end and thereby achieving the effect of coordinated control of multiple energy sources. This flexible access method enables quick utilization of power resources and is also conducive to quality control of electric energy.
Microgrid mainly adopts a distributed access method for individual power supply. The main power source for supplying microgrid is clean energy. Therefore, battery energy storage system technology in microgrid has great environmental friendliness and cleanness. At the same time, the storage performance of battery energy technology is very high, combined with clean energy power supply, it can fundamentally achieve conservation and recycling of power resources, and achieve high performance and low energy consumption operation goals, which is the greatest economic value of applying battery energy storage technology in microgrid.
The main advantage of applying battery energy storage system technology in microgrid lies in automation. In the entire application and operation process of battery energy storage system technology in microgrid, there is no need for manual operation and control. This is mainly due to the automatic balance function of the battery during its usage in microgrid, which can keep the battery energy storage in a balanced state continuously with the help of bidirectional AC converters.
Battery energy storage technology in microgrid also has strong interactivity. In the entire composition of the power system, there are mainly 10 kilovolt distribution systems, distributed power systems, and access power systems. In traditional distributed and access power system applications, there will be some degree of excessive loss of power resources. However, the application of battery energy storage system technology in microgrid can well avoid this problem. Since the operating voltage of the microgrid is relatively low, real-time energy exchange can be conducted between the microgrid and distribution network, thereby achieving the interactive utilization of diversified energy sources and comprehensive management of power resources during the operation of the microgrid.
