The development and extension of microgrid can fully promote the large-scale access of distributed power sources and renewable energy, realize the highly reliable supply of various energy forms to loads, and is an effective way to realize active distribution network, making the transition from traditional power grid to smart grid.

[0003] Energy storage batteries are one of the energy storage devices used in most microgrids. It is a process of storing energy through media or equipment and releasing it when needed. Energy storage technology is a key technology to solve the problems of large-scale access to renewable energy and wind and solar power abandonment.

However, energy storage batteries in microgrids may experience abnormal heating and thermal runaway during centralized operation. With the recycling and reuse of retired power batteries and the increase in battery quality, quantity, capacity, and energy density, the probability and degree of danger of battery energy storage power station accidents have also greatly increased. Therefore, real-time monitoring and early warning of the battery operation process are important measures to ensure the safe operation of microgrids and promote the sustainable development of energy storage technology.
