摘要
提高配电网在故障情况下的自愈能力对于保障电网的稳定运行和用户用电的可靠性,以及电网的智能化程度具有重要意义。针对含有分布式新能源的配电网系统,文章研究了考虑分布式新能源发电及其随机性的配电网自愈控制优化运行问题。文中论述了含有分布式光伏新能源的配电网系统运行结构和模型,在考虑分布式光伏发电不确定性的基础上构建了配电网自愈控制的含混合整数的随机规划模型,并提出利用场景树方法和线性化方法将原自愈控制问题转化为混合整数规划进行求解,通过实验分析验证了在考虑分布式电源和负荷的随机性时文中所述自愈控制方法的有效性。
Improving the self-healing ability of distribution network under fault conditions is of great significance to ensure the stable operation of power grid,the reliability of power supply to users,and the intelligence of power grid.For distribution network with distributed new energy,this paper studies the self-healing control problem of distribution network considering the randomness of distributed new energy generation.This paper discusses the op-eration structure and model of distribution network with distributed photovoltaic new energy,constructs a mixed-in-teger stochastic programming model for distribution network self-healing control considering the uncertainty of dis-tributed photovoltaic power generation,and proposes the scenario tree method and linearization method to transform the original self-healing control problem into a mixed-integer linear programming for solution.The effectiveness of the self-healing control method considering the randomness of distributed power generation and load described in this paper is verified by experimental analysis.
