In order to control access capacity and capacity balance of distributed generation,this paper designs a distributed gen-eration access capacity balance control system based on ARM.The system is composed of upper computer display module,ARM control module,lower computer detection module,balance control module and protection alarm module,etc.The system uses the EXP-LM3S811 ARM microcontroller whose core is the ARM Cortex-M3 to achieve distributed power data acquisition,au-tomatic protection,temperature and lower computer capacity balance control.The optimal access capacity calculation model is built,and the firefly algorithm is used to solve the model.According to the calculation results of the optimal access capacity,the access capacity of distributed generation is dynamically balanced by the balance control module.The application results show that the error of information transmission and the calculation error of optimal access capacity of the system are less than 5 μrad and 0.5％respectively,which indi-cates that the system can significantly improve the access capacity balance of distributed generation and has strong practical ap-plication value.
