English: With the transformation of energy structure, the proportion of distributed renewable energy generation such as solar and wind power in distribution networks continues to rise, bringing many challenges. On one hand, the intermittency and volatility of their output can easily cause voltage fluctuations and limit violations. On the other hand, changes in traditional distribution network structures lead to increased short-circuit currents and difficulties in relay protection coordination. Therefore, there is an urgent need for in-depth research on protection control and simulation technologies for distribution networks with distributed renewable energy generation to ensure safe, stable, and efficient operation of distribution networks.

中文: 随着能源结构转型，太阳能、风能等分布式新能源发电在配电网中的占比持续攀升，带来了诸多挑战。一方面，其出力的间歇性与波动性，易引发电压波动、越限等问题；另一方面，传统配电网结构改变，致使短路电流增大、继电保护协调困难。因此，亟需深入研究含分布式新能源发电的配电网保护控制与仿真技术，确保配电网安全、稳定、高效运行。
