用户习惯分析不同类型车辆的用户充电行为规律，可获得充电需求的空间和时间分布，指导充电设施规划和建设
and use their habits so as to obtain the spatial and temporal distribution of charging demand and guide the planning and construction of charging facilities.

电网可靠性影响因素分析 以提高配电网可靠性为目标
Analyses are factors affecting greater reliability in order to improve the reliability of distribution network.

从网络结构
Feature is related to reliability are extracted from network structure,

设备水平
equipment level,

用户构成等方面提取与可靠性相关的特征
user composition and other aspects.

识别薄弱环节和权力等级

分析最佳的可靠性提升路径，指导配电规划和投资
the optimal reliability improvement parth as analyzed to guide the distribution planning and investment

好吧
Okay,

现在让我们转到第二个话题
now let's move to the second topic

最优操作
optimal operation

基于WAMS的电网运行态势评估:
Wide area measurement system based the power grid operation situation assessment,

针对WAMS历史信息
According to the WAMS historical information,

或各种预想故障的时域仿真结果对大电网广域量测信息或者仿真结果进行关联特性挖掘
or the time domain simulation results of virus expected faults.

我们
we mine the association characteristics

获得不同运行场景下的
of the white area measurement information or a simulation results of the large power great.

大电网能量传递
The timespace correlation characteristics of energy transfer and disturbance,

和扰动传播时空关联特性
propagation indifferent operation sceneries are obtained,

结合随机矩阵、熵、时间序列等方法
combined with random matrix, entropy, time series and other methods

对系统静态、暂态稳定态势进行早期预判
The early prediction of static and transient stability situation of the system is carried out.

定量评估故障地点、故障类型等因素对稳定性的影响
The influence of Fords location for the type and other factors on stability is quantitatively evaluated.

识别系统薄弱环节
The weak links of the system are identified.

为安全稳定控制策略的制定提供依据
And the basis for the formulation of a security annister ability controls to add today is provided.

电网运行风险评估
Power grader operation risk assessment.

随着现代电力系统规模的不断扩大，特高压线路的增多
With the continuous expansion of modern power system and the increase of new UHV lies,

网架结构日益复杂，电网运行面临的潜在风险也越来越多
the great structure as becoming more and more complex and the potential risks of great operation are also increasing.

融合体量更大、类型更多的电网设备静态参数与电网运行数据
The static parameters and operation data are power grade equipment with a larger volume,

更加客观地分析、归类输配电网的运行状态以及风险等级
and more types are integrated to analyze and classify the operation status and the risk level of a transformation and distribution grid more objectively.

最佳操作的第三部分是现在的技术或宽松的监控
The third part of optimal operation is non-technique or line lose monitoring,

这很有侦探意味
which is very detective.

在营销数据与配用电数据贯通融合的基础上
Based on the integration of marketing data and distribution data.

通过分析历史负荷曲线
Through the analysis of historical load curve

负载电压以及其他相关事件
load voltage and other related events.

检测出线损异常状况，判断线损异常类型
The abnormal augmentation of outgoing lie lose as detected and the type off of a normal ly lose as determined

通过进一步识别非技术性线损模式
by further identifying the noun-technical line loss mode

评估其属于
We can evaluate whether it belongs to the intentional behavior,

窃电
such as stealing electricity,

私自改造电表
transforming electricity meters without permission.

恶意损坏电表等有意行为
maliciously damaging electricity meters

还是属于电表运行

or it belongs to the unintentional behavior,such as a spontaneous operation,

自发故障
