However, wind energy and solar energy resources have the characteristics of instability and discontinuity when generating electricity, which makes it difficult to promote wind energy and solar energy resources on a large scale in practical applications. To solve this problem, the addition of traditional diesel generator sets can solve this problem.
[0003] Since wind power generation devices, solar power generation devices and diesel generator sets are arranged in different places, it is extremely inconvenient for personnel to carry out maintenance, and there is no need to lay a large number of wire networks.

In addition, in the existing devices, the diesel generator set and the energy storage device are too close, which can easily cause the energy storage device to overheat, affecting the normal operation of the equipment.
