Abstract: With the continuous improvement of science, technology, and economic level, the diversification of electricity energy demand is also rapidly growing. Distributed power sources have been widely used due to their advantages such as cleanliness, low-carbon, and high efficiency. However, the randomness and volatility of new energy, as well as the electronic nature of power, pose new challenges to the safe and stable operation of distribution networks. This article analyzes the current situation of distributed photovoltaic grid connection in this region, summarizes the impact of distributed photovoltaic grid connection on the reliability of distribution network operation, and proposes corresponding strategies. Make every effort to serve the last mile of rural revitalization and new urbanization. Comprehensively promote the comprehensive utilization of clean energy and continuously improve the sense of gain and happiness of the people.
