A standard expected value model for multi-objective multi-stage transmission planning is presented to realize the transmission optimal planning with the control of line overloading risks. In this model, a constraint of overloading risks is built with expected value and standard deviation of random line active power and two objectives are given as expected value of the average power loss and discount value of the investment cost. By modeling uncertain informations with probability theory, the probabilistic DC power flow is adopted for the correlated calculations among random variables in the planning model.4 A novel multi-objective transmission planning approach that considers transmission investment profit is proposed. Requests for transmission investment profit and social welfare are involved in the proposed planning approach.

But it is just the Gump like this who creates trends one by one, from rugger to jog across America, from representing for table tennis bat to investing in computer field, numberless people have got inspiration from him, although he is unintentional in doing these which make himthe pioneer of the trends in that era.

就是这样阿甘却创造了一个又一个的潮流，从橄榄球到横穿美国，从带言乒乓球拍到投资计算机领域，加之无数人从他那里得到灵感，尽管这都是他无心为之，却使他成为了时代潮流的先锋。

If we say that in the LCD TV industry development in the South China Sea is in line with the trend, then, from now on, the South China Sea will lead the trend of flat-panel display industry!

如果说，在液晶电视产业发展方面南海是顺应了潮流，那么，从现在开始，南海将引领平板显示产业的潮流！

Based on this principle, the proposed algorithms, such as fast search for transmission section based graph theory, fast search for flow transferring shortest path and the FTRF, are developed under Microsoft Visual C++ environment by using the Standard Template Library in order to simplify the development effort.

基于以上原理，用C++计算机编程语言编制了基于图论的输电断面快速搜索算法、基于图论的潮流转移最短路径快速搜索算法与基于直流潮流的分布系数法，并运用Visual C++计算机编程语言搭建了输电断面安全性保护的仿真平台。

The results show that the tidal property in Dongshan Bay belongs to regular semidiurnal tide. The action of tide current is strong and the flow velocity is currently more than 100cm/s in the bay mouth area and the channel.

结果表明，东山湾主要属于往复式的规则半日潮流，潮流作用较强，其口门处和湾内水道上的实测最大流速一般大于100cm/s。

In every subarea system, the sequential quadratic programming algorithm is used to solve the optimization problem of the subarea system.

采用构造辅助问题的方法进行分布式并行计算，将大型互联电网最优潮流问题分解为多个子网的并行潮流优化问题，在每个子网中，采用序列二次规划法求解子系统的的优化问题。

Each time the current changes directions, a period of no current, known as slack water, intervenes.

每当潮流改变方向时，中间都有一段叫做平潮的无潮流阶段。

In this paper, the line blocking situation, the exchange of optimal power flow analysis of the circuit system, each node under congestion pricing, as well as trends such as changes in the slip road was completed in the Matlab environment to the IEEE14 bus system route blockage occurs in case of simulation and data analysis and achieved good results.

本文针对线路的阻塞情况，用交流最优潮流分析了线路阻塞情况下系统各节点电价以及支路潮流等变化，完成了在Matlab环境下对IEEE14节点系统发生线路阻塞情况下的仿真和数据分析，取得了较好的效果。

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 L-M method based on the subdifferential.

将概率最优潮流表述为随机非线性规划问题后，利用非线性互补函数将该问题的KKT条件进行转化，基于转化后的非线性代数方程组，利用一次二阶矩法确定了以待求量的数字特征表示的概率最优潮流模型，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L-M方法求解。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
