摘要
现有的分布式电源规划方法所考虑的指标较少,不适用于更为复杂的主动配电网。因此从多指标、多待选方案的角度出发,提出了一种分步筛选法。首先将各指标分为两类:在第1次筛选中考虑技术性指标,由模糊综合评价法确定目标函数,利用改进的禁忌模拟退火算法得到若干待选方案;在第2次筛选中引入经济性指标,利用层次分析法得到综合最优方案。其次,通过多种主动配电网调节措施对电网参数的动态调整,实现全天不同光照和负荷条件下的指标综合最优。最后将该方法应用于IEEE14节点环网算例,在方案选取和动态调整两个过程中分别验证了对各指标的优化作用。
The existing planning methods for distributed generations only consider few indexes,thus they are not suit-able for the active distribution network（ADN）,which is even more complex. Therefore,a step-wise screening processis proposed in this paper from the aspects of multiple indices and alternative schemes. First,the indices are divided intotwo types：technical indexes are considered in the first screening,the objective function is determined by fuzzy compre-hensive evaluation（FCE）,and several alternative schemes are obtained utilizing the improved simulated annealing al-gorithm based on tabu list;economic indices are introduced in the second screening,and the comprehensive optimal so-lution is obtained using analytic hierarchy process（AHP）. Then,dynamic adjustment is realized by adopting differentmeasures of ADN,and multi-index optimization is realized under the condition of different illuminations and loads allday long. Finally,this method is applied to the simulation of an IEEE 14-node system,which verifies its optimization ef-fect in the process of screening and dynamic adjustment.
