摘要：

The rapid development of society has led to a rapid increase in the demand for electricity and the scale expansion of power systems, and their stable operation is a top priority. This paper briefly introduced the structure of the photovoltaic microgrid and the electrical automation control strategy for stable grid-connected microgrid operation, improved the electrical automation control strategy with the extreme learning machine (ELM) algorithm, and conducted simulation experiments on two electrical automation control strategies in MATLAB software. The results showed that the voltage of the microgrid fluctuated when the load in the microgrid and the output of the photovoltaic power supply changed, and both automatic control strategies suppressed the fluctuations, and the improved automation control strategy had a better suppression effect and took less time to restore microgrid stability. © 2022, Cefin Publishing House.
