In the POPF model, wind farm is modeled by the probabilistic wind farm model considering the reactive power-slip characteristic, and the inequality constraints include not only the unit output constraints, the ratio constraints, the voltage constraints and the line current constraints but also the reactive compensation capacity constraints in wind farm and the system climbing capacity constraints per minute. By introducing the NCP function, the KKT conditions of POPF system are transformed equivalently. Based on the transformed nonsmooth nonlinear algebraic equations, the FOSMM is used to determine the POPF model expressed by the numerical characteristic of variables. The model includes nonsmooth functions, so it can be solved by a semismooth Newton-type method based on the subdifferential.
概率最优潮流模型中,风电场采用考虑无功功率—滑加热器差特性的风电概率模型,不等式约束中除了机组出力约束、有载调压变压器变比约束、电压约束和支路电流约束,也考虑了风电场无功补偿容量约束、系统的分钟级爬坡能力约束;使用非线性互补函数将概率最优潮流的KKT条件转化为一组包含有不光滑函数的非线性代数方程组,然后基于一次二阶矩法确定了以待求量的数字特征表示的POPF模型,由于该模型包含不光滑函数,因此采用基于次微分的半光滑牛顿型方加热器法求解。

The problem has been studied from two sides, firstly, from the viewpoint of applicability, based on the development strategic objectives of the oil company, with the aim to unify the exploration and extraction decisions of the resources in an integrated framework, and integrate the macro economic and technical objectives with micro economic and technical models of an oil well, an integrated non-linear dynamic optimal control model has been constructed, the objective is the benefit maximum of the exploration and extraction of the resources, and the optimalstrategies are obtained by changing the problem into a non-linear mathematical programming problem, on the other hand, from the more macro level, based on the analysis of the characteristics of the exploration and extraction activities of oil and gas resources, a conclusion is easily deduced that the procedure is full of randomicity, then discovering procedure of oil deposit is proved to be a Poisson process, and the reserves process is a supermartingale process, so the model of exploration discovery rate and the reserves model could be constructed.

Fisher criterion assumes that each sample has a unimodal,symmetric distribution for each class.However,when the training sample size is large and their distributions are multimodal or skewed,the definition of classical Fisher criterion can not correctly reflect the distribution of the data in the sample space,in that case,the sets of discriminant vectors are not optimal virtually.
Fisher准则函数的前提条件就是假设每类样本数据满足单峰高斯分布,即各类样本在模式空间的分布近似椭球状,但是当训练样本数据较多且呈多峰分布时,传统的Fisher准则函数并不能准确反映样本数据的分布,显然基于Fisher准则函数的线性判别分析得到的最优判别矢量集也不是最优的。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.
并且得出,每个树种在树冠内相对高度上的叶量的垂直分布是不同的,天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小,约占10%左右;在树冠的中部以及中下部(0.4CL~0.8CL),叶量所占比例最大,几乎集中了整个树冠60%~75%的叶量;而在树冠的下部(0.8CL以下),几乎占很少的叶量,大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系,并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木,并不是传统意义上的全部竞争木;本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况,并采用等树冠投影面积法把树冠分为5级,这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想,用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型,设计了10个与林学意义相一致的约束条件,并采用0-1整数规划的思路,在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例,具体计算出了每株采伐木,经过择伐后,目标函数值按模型设计的要求发生了极大的改变,增加了5倍多,说明了最后这个解的优良性,满足了设计的要求。
