Abstract

The optical storage DC microgrid is taken as the research object. In view of the general situation of unstable output of photovoltaic cells, the energy storage system is introduced to absorb power in case of excess photovoltaic output power and release power in case of insufficient photovoltaic output power, so as to maintain the power balance of microgrid. The stability of bus voltage in DC microgrid is an important index of power balance in the system. Therefore, maintaining the stability of DC bus voltage is an important way to maintain the power balance of microgrid and system stability. Aiming at the problem of bus voltage stability, a method based on single neuron PID adaptive control is proposed. Taking bus voltage as the control variable, the influence of single neuron PID controller on Bidirectional DC-DC converter is studied. The results show that the single neuron PID adaptive control method has a good effect on controlling the voltage stability of DC bus, enhances the anti disturbance ability of the system and improves the operation stability of optical storage microgrid.
