摘要
传统配电网制定新接入负荷业扩方案时,没有考虑其时序和可控可中断负荷,易使同特征负荷集中接入同一电源,造成该电源点的峰值、谷值叠加,使设备利用率和业扩能力低下。对此,提出考虑负荷时序与电源匹配的配电网最优业扩模型。首先,提出改进星雀算法的模糊C均值聚类方法获取时序负荷聚类库;其次,提出基于隶属度函数的新报装用户时序负荷模式识别方法;再次,将电源点可控可中断负荷融入上述模型,建立配电网业扩最优模型;最后,以某实际电网为例进行仿真验证,表明所提方法的有效性。
When business expansion plans of new access loads are formulated for traditional distribution networks,their timing and controllable and interruptible loads are not considered,which can easily cause loads with the same characteristics to be concentrated in the same power source.As a result,the peak and valley values of the power point are overlapped,and thus equipment utilization and business expansion capacity are lowered.In response,this paper proposes an optimal business expansion model for distribution networks,which considers load timing and power source matching.Firstly,the paper proposes a fuzzy C-means clustering method based on the improved nutcracker optimization algorithm to obtain the temporal load clustering library.Secondly,it proposes a temporal load pattern recognition method for new installation users based on membership function.After that,the controllable and interruptible load of the power point is integrated into the above model,and an optimal model for the business expansion of the distribution network is established.Finally,simulation verification is conducted using an actual power grid as an example,demonstrating the effectiveness of the proposed method.
