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.
Multi-objective Planning of Distribution Framework Considering High-proportion Integration of New Energy Generations
With the increase of new energy generations integrated to power networks,the planning process may overly fo-cus 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 distri-bution 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 optimiza-tion 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 supe-rior to both of the methods in references when coping with distribution framework multi-objective planning,and hence have strong practicality.
