摘　　要：随着新能源接入比例的增大,在规划过程中可能过于注重经济性和可靠性的优化,而忽视了电压稳定性的重要性,导致电压稳定性指标高,电压不稳定。为此,研究考虑高比例新能源接入的配电网网架多目标规划方法。首先,建立涵盖多个维度的配电网网架多目标规划函数。其次,为确保网架规划的可行性和合理性,制定一系列约束条件。接着,确定网架优化规划的编码方式,为配电网的优化设计提供有效指导,最后,运用先进的优化算法对网架多目标规划问题进行求解,以寻找不同目标之间的最优平衡点。实验结果表明:在进行配电网网架多目标规划时所提方法的电压稳定性指标最低,而对比方法的电压稳定性指标都较高,故所提方法具有较强的实用性。With the increase of new energy generations integrated to power networks,the planning process may overly focus on optimizing economy and reliability,while neglecting the importance of voltage stability,resulting in high voltage stability indicators and unstable voltage.This work studied a multi-objective planning method for distribution framework considering high-proportion integration of new energy generations.First a multi-objective planning function for the distribution network framework that covers multiple dimensions was established.Second a series of constraint conditions were formulated to ensure the feasibility and rationality of the grid planning.Further the coding method for network optimization planning was determined,providing effective guidance for the optimization design of the distribution networks.Finally advanced optimization algorithms were used to solve the multi-objective planning problem and find the optimal balance point among multiple objectives.The proposed method was indicated by experiment to achieve voltage stability index superior to both of the methods in references when coping with distribution framework multi-objective planning,and hence have strong practicality.
