A novel clustering approach combining Kmeans++ and PAM was introduced to segment the daily load curve chronologically for the dynamic reconfiguration of distribution networks incorporating time-varying wind solar power and loads. Multi-objective dynamic reconfiguration model of distribution network based on the optimal objectives of comprehensive cost, voltage offset and load balance. To enhance the computational efficiency of the model, an INOA(improved Nutcracker optimization algorithm) was proposed, which used Tent mapping+quasi-reflection learning to provide high-quality initial population. Dynamic fitness-distance balance selection method and tangential flight strategy were introduced to enhance the global search capability. The Cauchy-Gaussian variation perturbation was incorporated to augment the algorithm’s capability to escape from local optima. Using the IEEE 33-node system as a basis, the outcomes indicate that the suggested approach effectively achieves optimal load distribution and efficiently addresses the restructured model.

针对风光荷时变的配电网动态重构问题,提出了一种Kmeans++融合PAM(Kmeans++-partitioning around medoid)聚类方法,按时间顺序划分日等值负荷曲线。以综合成本、电压偏移和负荷均衡度为优化目标构建配电网多目标动态重构模型。提出了一种改进星鸦优化算法(improved Nutcracker optimization algorithm,INOA)提升模型求解效率,利用Tent映射+准反射学习提供优质初始种群,引入动态适应度-距离平衡选择方法和切线飞行策略提高全局搜索能力,加入柯西-高斯变异扰动克服局部最优。基于IEEE33节点系统进行对比分析,结果表明所提方法能够实现负荷最优划分并对重构模型进行高效求解。

A novel clustering approach combining Kmeans++ and PAM was introduced to segment the daily load curve chronologically for the dynamic reconfiguration of distribution networks incorporating time-varying wind solar power and loads. Multi-objective dynamic reconfiguration model of distribution network based on the optimal objectives of comprehensive cost, voltage offset and load balance. To enhance the computational efficiency of the model, an INOA(improved Nutcracker optimization algorithm) was proposed, which used Tent mapping+quasi-reflection learning to provide high-quality initial population. Dynamic fitness-distance balance selection method and tangential flight strategy were introduced to enhance the global search capability. The Cauchy-Gaussian variation perturbation was incorporated to augment the algorithm’s capability to escape from local optima. Using the IEEE 33-node system as a basis, the outcomes indicate that the suggested approach effectively achieves optimal load distribution and efficiently addresses the restructured model.

为达成“双碳”目标,中国新型电力系统建设不断深化,分布式发电(distributed generation,DG)迅速扩张,其大规模接入对电网的可靠性、稳定性和经济效益提出了新的考验[1-2]。配电网重构是提升电网效率的关键策略,通过调整开关配置优化网络结构,旨在增强系统的可靠性和经济效益[3]。配电网动态重构问题可以划分为多个时间段的静态重构问题来解决,其结果反映了负荷和DG的动态变化,更切合实际[4-5]
配电网静态重构技术已经发展非常完善,但基于时段划分的动态重构研究较少[6]。文献[7]运用递归方法遍历每种时段划分方案,找到各分时段数下的最佳方案;计算损失函数随分时段数变化的速率,选择变化速率最大时对应的分时段数作为最优分段数,该方法能够保证时段最优划分,但数学推导过程复杂,计算量较大。文献[8]以基于马氏距离的动态时间归整(dynamic time warping,DTW)值为相似度量,提出分段指标为目标值,进行时段划分同时根据分段指标最大找出最优分段数。文献[9]提出了欧式距离和余弦距离组成的综合距离作为相似度量,围绕中心点划分(partitioning around medoid,PAM)中引入模拟退火提高时段划分准确度,最后“拐点法”确定最优方案。文献[10]考虑到了负荷曲线形态上的相似性,提出了外层皮尔逊内层欧氏距离为相似度量的双层聚类,提高了时段划分的准确性。以上方法虽然能有效划分时段,但未充分考虑负荷的时序性,等值负荷归类后还需根据时间轴进行二次划分。基于此,提出一种改进PAM聚类方法,使得输出结果具有严格的时序特性。
配电网重构是多项式复杂程度的非确定性(non-deterministic polynomial,NP)问题,利用智能算法求解相比传统数学优化方法具有一定的优越性。文献[11]以系统损耗和电压偏移为优化目标,采用改进灰狼优化算法求解,提升了系统运行水平。文献[12]以系统运行成本和电压偏移为目标函数,应用改进哈里斯鹰算法求解重构模型,提高了系统运行经济性与稳定性。文献[13]同样以系统运行成本和电压偏移为目标函数,应用NSGA-Ⅱ改进算法求得帕累托前沿解集,通过模糊决策确定最终方案,全方位提升了系统运行水平。文献[14]以网损、平均和最小安全系数为目标函数,以约束指导目标求解过程,通过改进鼠群算法求解模型,有效提升系统运行稳定性。但同时考虑负荷与DG时变性,并针对系统综合成本及负荷均衡度等多目标开展配电网动态重构的研究还相对较少。
现利用改进Kmeans++-PAM对等值负荷预测曲线进行时段划分。考虑到配电网最基本的运行稳定性以及经济性要求,以综合成本、电压偏移和负荷均衡度为目标,构建多目标函数,并将改进星鸦优化算法应用于含DG的配电网动态重构中,求得各时段最优开关组合。
聚类可以挖掘数据内在规律,通过聚类整合相似数据,进而简化复杂问题[15]。现有的聚类方法很多,像Kmeans和PAM都是基于中心点的聚类算法,相比Kmeans,PAM的中心点是数据中真实存在的点,很大程度避免噪声点的干扰,聚类效果更佳。
PAM聚类具体流程如下。
(1)数据集X包含n个样本点,分为k类,随机选取k个样本点作为初始聚类中心。
(2)计算剩余n-k个点到k个聚类中心的距离,并将这些点逐一分配至最近的聚类中心,从而形成k个簇。
(3)每个簇重复以下步骤:选取簇内一点作为临时中心,计算簇内其他点到该点的总距离,遍历簇内所有点,找出使得总距离最小的点,并将其设为该簇的新聚类中心。
(4)若达到最大迭代次数,则输出结果;否则重复执行步骤(2)和步骤(3)。
其中k个初始对象的选取对PAM聚类效果影响较大,特别是当k值较小时,初始聚类中心之间的距离不够大,直接导致聚类效果下降。Kmeans++的初始化可以使初始聚类中心之间的距离尽可能远,有效防止局部早熟收敛,因此引入该策略提升PAM性能。
Kmeans++初始化具体流程如下。
(1)从数据集X=[X1,X2,…,Xn]中随机选择一个样本点作为第一个聚类中心点。
(2)数据集X中除已经被选为聚类中心外的样本点称为待选点,每个待选点Xi执行相同操作:计算其与最近聚类中心之间的距离Di
(3)计算每个待选点Xi被选为聚类中心的概率Pi
P i = D i 2 i A ( x ) D i 2
式(1)中:A(x)为待选点集。
(4)按照概率选择一个待选点为聚类中心并重复步骤(2)和步骤(3)直到得到k个初始化聚类中心。
配电网重构时段划分指根据电力系统的负荷特性和运行要求,将一定时间段分为不同的时段,在避免开关频繁动作的基础上尽可能达到降低网损和抬高电压等目标。
Kmeans++-PAM聚类进行配电网重构时段划分流程如下。
(1)预测一天的负荷曲线及DG出力,DG作为负的负荷加入负荷曲线中形成等值负荷曲线,设系统共有n个节点,以1 h为步长将一天划分为m个时间段,得到一个以时段为行,节点数为列的矩阵数据集X,X中的每个元素代表特定时段某一节点的功率值。
X = x 1 , 1 x 1 , 2 x 1 , n   x m , 1 x k , 2 x m , n
(2)利用上述Kmeans++初始化策略得到k个按时序排列的初始化聚类中心 X c = [ X c 1 ,     X c 2 , ,   X c k ] T,其中 X c i = [ X c i , 1 ,   X c i , 2 , ,   X c i , n ]ci(ci∈[1, m])时段的功率, X c i , jci时段节点j的功率。
(3)以欧式距离衡量数据间的相似性,计算每个点到相邻两个聚类中心的相似度sj,并划入相似度小的聚类簇中,同时得到相似度指标Sk
s j = m i n { d i s ( X c i , X j ) , d i s ( X c i + 1 , X j ) } , j = 1,2 , , m
式(3)中: X c i X c i + 1分别为Xj相邻的两个聚类中心。
S k = j = 1 m s j
(4)将每个簇内与其他点总距离最小的点设为新的聚类中心,仍用Xc表示。
(5)重复步骤(3)和步骤(4)直到k个分段点稳定不变或达到最大迭代次数。
相似度指标Sk随分时段数k的增加而递减[16],文中损失函数曲线法,以分时段数k为横轴,纵轴为相似度指标值Sk,得到分时段数与相似度指标的近似拟合曲线,寻找曲线“拐点”。如果拐点横坐标值为整数,即为最佳分段数;否则计算拐点横坐标相邻两个分时段数的斜率变化率,选择斜率变化率较大的分时段数作为最佳分时段数。

采用基于Pareto最优解思想的策略,通过比较连续两次迭代解集的满意度指标,以期找到整体目标的最优解决方案。

(2)存储阶段(开发阶段1),星鸦将觅食阶段找到的种子运输到不同的储藏点。数学建模为
X i t + 1 = X i t + μ X best t X i t λ + r 1 X A t X B t ,       τ 1 < τ 2 X best t + μ X A t X B t , τ 1 < τ 3 X best t l , τ 1 τ 2 τ 1 τ 3
式(19)中:λ为莱维飞行生成的随机数; X t b e s t为当前最优位置;l为从1~0线性递减的因子。

式(20)中: ϕ为[0,1]之间的随机数;Pa1取0.2。
(1)储藏搜索阶段(探索阶段2),星鸦利用参考点定位储藏位置,每个储藏位置有2个参考点,分别记为 R P i , 1 t R P i , 2 t
RP i , 1 t = X i t + α cos θ X A t X B t + α RP , θ = π / 2 X i t + α cos θ X A t X B t , θ π / 2
RP i , 2 t = X i t + { α cos θ U L τ 3 + L + α RP } U 2 , θ = π / 2 X i t + α cos θ U L τ 3 + L U 2 , θ π / 2
式中:
α = 1 t T max 2 t T max , r 1 > r 2 t T max 2 t , r 1 r 2
$\overrightarrow{U_2}= \begin{cases}1, & \vec{r}_2< P_{\mathrm{rp}} \\ 0, & \vec{r}_2 \geqslant P_{\mathrm{rp}}\end{cases}$
式中: R P i , 1 t R P i , 2 t分别为第t代第i个星鸦探索储藏时的1号参考点和2号参考点的更新位置;θ为以星鸦位置为中心对参考点和储藏点视角夹角;RP为一个随机参考位置;α由式(23)生成;U2由式(24)生成;Prp取0.2。
利用1号参考位置更新星鸦当前位置,即
$\vec{X}_i^{t+1}= \begin{cases}\overrightarrow{X}_i^t & f\left(\overrightarrow{X}_i^t\right) < f\left(\overrightarrow{\mathrm{RP}}_{i, 1}^t\right) \\ \overrightarrow{\mathrm{RP}}_{i, 1}^t & f\left(\overrightarrow{X}_i^t\right) \geqslant f\left(\overrightarrow{\mathrm{RP}}_{i, 1}^t\right)\end{cases}$
式(25)中:f为适应度函数。
(2)重获阶段(开发阶段2),利用1号参考点找到的储藏中,可能有种子,也可能没有,建模为
$\begin{aligned} & X_{i, j}^{t+1}= \\ & \begin{cases}X_{i, j}^t, & \tau_6 < \tau_7 \\ X_{i, j}^t+r_1\left(X_{\text {best }, j}^t-X_{i, j}^t\right)+r_2\left(\overrightarrow{\mathrm{RP}}_{i, 1}^t-X_{C, j}^t\right), & \tau_6 \geqslant \tau_7\end{cases} \end{aligned}$
式(26)中: X b e s t , j t为当前最优位置的第j维数值;τ6τ7为[0,1]之间的随机数。
如果星鸦忘记了1号参考点,那么将利用2号点进行搜索,建模为
X i t + 1 = X i t , f X i t < f RP i , 2 t RP i , 2 t , f X i t f RP i , 2 t
$\begin{aligned} & X_{i, j}^{t+1}= \\ & \begin{cases}X_{i, j}^t, & \tau_8 < \tau_9 \\ X_{i, j}^t+r_1\left(X_{\text {best }, j}^t-X_{i, j}^t\right)+r_2\left(\overrightarrow{\mathrm{RP}}_{i, 2}^t-X_{C, j}^t\right), & \tau_8 \geqslant \tau_9\end{cases} \end{aligned}$
式(28)中:τ8τ9为[0,1]之间的随机数。
上述两阶段按式(29)进行轮换,保证探索和开发的平衡。

式(29)中:r4r5ϕ为[0,1]之间的随机数; P a 2取0.4。
如果初始种群成员能够均匀地散布在整个解空间中,这将有助于算法更有效地找到全局最优解,并且提高求解速度。原始NOA算法采用随机初始化,很难保证初始解在解空间的均匀分布,进而影响配电网重构结果。混沌序列具有确定性、敏感依赖初始条件和遍历性,其中Tent映射能产生均匀分布的序列,因此用Tent 映射来初始化星鸦种群。
x t + 1 = x t α , 0 x t α 1 x t 1 α , α x t 1
式(30)中: α取0.499。
由于Tent 映射对初始条件敏感,特别是数据量较小的情况,需要合适的初始值才能使生成数据均匀分布在解空间。为了得到均匀分布且质量较高的解,引入文献[19]提出的准反射学习策略。如图1所示,x是由Tent映射生成的初始解,以解空间中点进行反向得到反向值xo,反向解xqo在[(lb+ub)/2, xo]之间随机生成,反向解同样以解空间中点进行反向得到反射值xr,反射解xqr在[xr, (lb+ub)/2]之间随机生成。
x i q o = r a n d l b i + u b i 2 , x o i
x i q r = r a n d l b i + u b i 2 , x r i
式中:ublb分别为解空间的上、下界;xo为解初始解x关于解空间中心的对称点;xr为反向解xqo关于解空间中心的对称点;i为解的维度。
比较Tent解和其生成的准反射解的适应度值,适应度较优的选入最终的初始化种群。
原始NOA算法性能强大,但在某些问题上难以避免局部最优解。针对配电网重构,对NOA算法的探索机制进行了改进,以提高其实用性。
“切线飞行”是切线搜索算法中提出的一种以切线函数为基础的步长策略[20]。这一方法的设计旨在提高搜索空间的探索效率[21]。切线飞行具体公式如下
X t + 1 = X t + s t e p t a n θ
s t e p = 0.3 ( r a n d - 0.5 ) n o r m ( X b e s t ) × l n ( 1 + 10 d i m / t )
式中:X为种群位置;step为步长;θ决定了新解与当前解的距离,θ越接近0距离越小,θ越接近π/2距离越大;step由式(34)生成;tanθ在[0,π/2.1]之间随机生成;norm为欧式范数;dim为解的维度。
将切线飞行策略引入探索阶段1,如式(35)所示。
X i t + 1 = X i ,   j t + s tep tan θ ,   τ 1 < τ 2 X m ,   j t + γ X A ,   j t X B ,   j t + μ r 2 U j L j , τ 1 τ 2 t T max 2 X C ,   j t + μ X A ,   j t X B ,   j t + μ ( r 1 < δ ) r 2 U j L j , τ 1 τ 2 t > T max 2
动态适应度-距离平衡选择方法(dynamic fitness distance balance, dFDB)[22]是在适应度-距离平衡选择方法[23]基础上提出的,相比原始方法可以通过调节适应度和距离所占比重来平衡探索与开发。该方法通过适应度-距离值指导种群个体更新,相比NOA算法中的随机选择有更好的指导作用。假设种群X=[X1,X2,…,Xn]T,每个候选解都有相应的适应度值,以该种群最大最小适应度值的差值为基准值,将每个候选解适应度值归一化得F=[F1,F2,…,Fn]T;第i个候选解到当前最优解的欧式距离由式(36)得到,以该种群其余候选解到当前最优解的最大最小距离差值为基准值归一化得D=[D1,D2,…,Dn]T。使用归一化的适应度值和距离值计算每个候选解的dFDB评分Si,如式(37)所示。
  i = 1 n X i , D i = [ ( x i , 1 - x b e s t , 1 ) 2 + ( x i , 2 - x b e s t , 2 ) 2 + + ( x i , m - x b e s t , m ) 2 ] 1 / 2
  i = 1 n X i , S i = ω d F D B D i + ( 1 - ω d F D B ) F i
ω d F D B = h m a x F E ( 1 - l b ) + l b
m a x F E = T m a x H
h = m o d ( t , m a x F E )
式中:ωdFDB为距离权重;maxFE为一个ωdFDB更新周期所迭代的次数;Tmax为最大迭代次数;H为更新频率,决定了ωdFDB更新周期;mod(x,y)表示xy求余;lbωdFDB的下限,lb在[0,0.5]之间取值;ωdFDB越接近0开发性能越强,越接近1探索性能越强,取lb为0.3可以保证较强的探索性能。
选择dFDB评分最高的候选解指导NOA算法探索阶段2的选择过程,具体公式为
RP i , 1 t = X i t + α cos θ X A t X S t + α RP , θ = π / 2 X i t + α cos θ X A t X S t , θ π / 2
式(41)中: X i t为第 t次迭代中的第 i个解; X A t t次迭代时随机选择的一个解; X S t t次迭代时dFDB评分最高的候选解。
为了增强改进算法搜索性能,在开发阶段2中引入柯西-高斯变异扰动策略[24],式(25)和式(27)改进如式(42)和式(43)所示。
X i t + 1 = X i t 1 + μ 1 Cauchy 0 , 1 + μ 2 Gauss 0 , 1 ,       f X i t < f RP i , 1 t RP i , 1 t , f X i t f RP i , 1 t
X i t + 1 = X i t 1 + μ 1 Cauchy 0 , 1 + μ 2 Gauss 0 , 1 ,       f X i t < f RP i , 2 t RP i , 2 t , f X i t f RP i , 2 t
式中: μ 1 = 1 - t 2 /   T m a x 2; μ 2 = t 2 /   T m a x 2;Cauchy(0,1)为标准柯西分布;Gauss(0,1)为标准正态分布。
前期以柯西扰动为主,有利于探索;后期以高斯扰动为主,提升收敛精度。
具体重构步骤如下,重构流程图如图2所示。
步骤1 利用Kmeans++-PAM对负荷和DG预测值进行时段划分,获得最优分时段方案。
步骤2 采用文献[17]中的潮流计算编码方式进行整数型编码。
步骤3 设置算法参数:种群数N,维度M,最大迭代次数Tmax,解空间的上界UB和下界LB
步骤4 使用Tent映射+准反射学习策略初始化种群,计算每个候选解的适应度。
步骤5 随机选择觅食和存储策略与储藏搜索和重获策略。
步骤6 如果执行觅食和存储策略,按照式(20)选择式(35)或式(19)更新候选解。
步骤7 如果执行储藏搜索和重获策略,按照式(29)选择式(26)、式(28)、式(42)或式(43)更新候选解。
步骤8 贪婪选择:新解若适应度更低则替换,否则保留原解。
步骤9 若迭代次数达上限,则输出最优解;未达到则返回步骤5。
应用IEEE33节点系统进行仿真分析,线路及负荷预测数据来源于文献[9],系统总负荷3 746 kW+j2 352 kVar,基准值VB=12.66 kV、SB=10 MW,系统结构如图3所示。配电网负荷分为商业负荷、居民负荷和工业负荷,其最大负荷分别为2.017 2、1.375 2、1.065 6 MW,配电网负荷系数如图4所示。各时段风光出力数据参照文献[25]。节点14、节点22、节点32接入光伏(photovoltaic,PV),最大功率450 kW;节点7、节点25接入风电(wind turbine,WT),最大功率405 kW。风光出力系数如图5所示。网损成本设为0.7 元/(kW·h),单个开关动作成本为7 元/次。
将1 d的等值负荷以1 h为步长划分为24个基本时段,采用Kmeans++-PAM聚类算法进行时段划分,求出各时段数下的等值负荷相似度指标值Sk,绘制相似度指标曲线如图6所示,根据“拐点法”可知最优分段数介于4~5。分时段数为3~6对应的相似度指标值如表1所示。
求出分时段数为4和5时的斜率变化率分别为1.384和1.796,因此,最终的最优分段数为5。时段划分最终结果为0~7 h、7~11 h、11~15 h、15~21 h、21~24 h,等值负荷曲线具体时段划分结果如图7所示。
以IEEE33节点系统为对象,网损为目标函数,将INOA算法与GWO、HHO和原始NOA算法进行比较。统一参数为种群数N=50,最大迭代数Tmax=100。HHO中能量初值E0=1;NOA中δ=0.05,Prp=0.2,Pa2=0.4;INOA参数同NOA,f=10。每种算法执行50次独立运算,得出平均结果,具体数据如表2所示。
表2可以看出,相比其他算法,INOA 算法的平均网损最小、迭代次数最少以及寻优率最高。虽然在平均耗时上不如 SWO 算法,但在寻优率方面,SWO算法仅为16%,极易陷入局部最优。各算法进化特性曲线如图8所示,INOA迭代7次收敛,相比其他算法收敛快精度高。综合来看,在配电网重构中,INOA算法寻优效果突出。
以一天24 h的重构结果进行对比分析,经过动态重构的多目标优化求解,得到部分Pareto前沿重构方案如表3所示,动态重构方案1、方案2、方案3和方案4分别以网损、电压偏移、负荷均衡度和按照第2节多目标优化策略得到的总目标满意度为目标函数得出的最优方案。
为了验证动态重构的优越性,将动态重构与其他重构策略进行比较如表4所示。
单一重构、全时段重构和动态重构方案1都是以网损为目标函数。从表4可以看出动态重构方案1相比未重构方案除开关动作次数外各项指标都更优;相比单一重构虽然开关动作次数和综合成本有所提高,但网损、电压偏移和负荷均衡度指标分别下降21.1%、18.5%和4.9%,而且在实际电力系统中,负荷和网损都是相当大的,降损相比减少少量开关动作带来的经济效益会更高;相比全时段重构,网损、电压偏移和负荷均衡度指标分别上升0.3%、0.5%和0.1%,全时段重构较优,但是全时段重构开关频繁动作,会给电力系统带来极大的不稳定性。未重构、单一重构、全时段重构和动态重构方案1各时段网损如图9所示,可以看到在负荷较重且波动比较大的情况下,动态重构方案1的降损效果显著。
上述4种方案一天内的电压分布如图10所示。可以看到动态重构明显提高了电压水平,大幅降低了电压波动性,提升电压质量的效果与全时段重构相近。综合来看,动态重构方法相比其他重构方法有一定优越性,更适合于实际应用。
为了更加清晰地比较这几种方案对系统稳定性的影响,取负荷较重的19:00—20:00的电压分布如图11所示。可以清晰地看出动态重构后,电压水平提升明显,电压分布更加均衡,此时未重构、单一重构、全时段重构和动态重构方案1的电压偏移分别为0.975、0.775、0.576、0.580 p.u.。从数据来看,动态重构相比不重构和单一重构提升电压水平较大,同时电压偏移指标非常接近全时段重构,说明动态重构方法的有效性。
配电网重构在实际应用中需要考虑多个目标,但一般很难让每个目标同时达到最优。利用Pareto前沿解集可以得到多目标模型中每个单目标函数的最优解,以及对每个目标都相对较优的解。动态重构各方案的指标对比如图12所示。在动态重构方案中,动态重构方案1的网损指标最优;动态重构方案2的电压偏移指标最优;动态重构方案3的负荷均衡度指标最优;动态重构方案4是以2.2节多目标优化后求解的结果,虽然它的网损、电压偏移和负荷均衡度三个指标没有一个达到最优,但是它的这三个指标同时接近最优,且开关次数和综合成本最优,达到了对每个目标都相对较优的效果,有非常高的实用价值。具体的方案选择,可以根据实际的需求来进行选择。
针对风光荷时变下的配电网重构问题,以综合成本、电压偏移和负荷均衡度为目标函数建立重构模型,并进行多目标优化;对时变DG和负荷,运用Kmeans++-PAM聚类方法对时间轴进行聚类,确定最佳重构时段数;提出改进的星鸦算法对重构模型求解。通过IEEE33节点系统进行仿真分析,得到以下结论。
(1)Kmeans++-PAM聚类方法能够精确识别时变负荷数据间的相似性进行时段划分,所提最优分段数确定方法有效平衡了划分时段数过多开关动作频繁与划分时段数不足达不到降损提压目的间的矛盾,为建立配电网动态重构模型打下基础。
(2)通过Tent映射+准反射学习提供优质初始种群,动态适应度-距离平衡选择方法和切线飞行策略提高全局搜索能力,柯西-高斯变异扰动克服局部最优,提升了原始星鸦算法在配电网重构中的运行效率和计算精度。
(3)建立以综合成本、电压偏移和负荷均衡度为目标函数的重构模型,求解得到部分Pareto前沿解,根据具体需求选择相应的解,有效提升了配电网实际运行经济性与稳定性。
