Description: 在电力市场改革的过程中，出现了许多新的问题：网络潮流的分布主要由电力交易 的分布所决定，电力交易以追求最大利润为目标，于是出现了电力系统中输电价格较低 的线路或电能价格较低的发电机组周围的线路负荷过重，从而增加了发生阻塞的可能 性。本文就电力市场中输电阻塞管理的办法以及阻塞费用的计算进行了讨论。-the electricity market reform process, the emergence of many new issues : the trend of the distribution network mainly by the distribution of power transactions by the decision to pursue electricity transactions for maximum profit, so a power system transmission lines with lower prices or lower the price of electricity generating units around the line overloading, thereby increasing the possibility of obstruction occurred. This paper on the electricity market transmission congestion management methods as well as obstruction of calculating the fees were discussed.

Description: 电力市场下确定无功源价值的方法探讨
因此提出了4种确定无功价值的方法：Vs法、PV曲线法、ERC法和Back．up法，分析了不同方法
的特点，最后以IEEE30节点系统为例进行了仿真计算，仿真结果表明无功源的价值取决于电网的结
构、无功源的位置以及系统的运行状态。-Electricity market to determine the source of the value of reactive power method is proposed to identify four kinds of reactive power values: Vs law, PV curve, ERC and Back. up method, an analysis of the characteristics of different methods, and finally to IEEE30 bus system simulation as an example, simulation results show that the value of reactive power source depends on the grid structure, the location of reactive power sources and system operation status.

Description: 这里介绍的案例研究演示如何使用MATLAB来建立测量的燃气经营权，在新英格兰的植物组合相关的风险的申请。在Excel中的应用与实施用MATLAB进行了分析所有的接口。该应用程序允许用户指定的7种植物，包括能力，热率，可变操作和维护成本，最低运行时的特点。这个组合可以用一个简单的调度backtested历史天然气和电力价格的策略来计算利润和机组运行的历史数据。风险措施，通过模拟计算到使用天然气和混合模型在MATLAB中实现，模拟市场价格为每调度方案和计算现金流量从厂房的运作产生未来的电力价格。该现金流量的分布进行分析，产生了90％和95％的现金流量在风险衡量每个工厂以及用于发电资产组合。这些功能全部是提出了一个简洁的Excel的前端。
题为“介绍ETRM为例”的文件将指导，通过分析不同的组件。-The case study presented here demonstrates using MATLAB to build an application for measuring the risks associated with a portfolio of gas-fired power plants operated in New England. The application has an interface implemented in Excel with all of the analytics performed by MATLAB. The application allows the user to specify the characteristics of the 7 plants including the capacity, heat rate, variable operation and maintenance costs and minimum run time. This portfolio can be backtested using a simple dispatch strategy on historical gas and electricity prices to compute historical profit and plant operation statistics. The risk measures are computed by simulating gas and electricity prices into the future using a hybrid model implemented in MATLAB, simulating the dispatch for each scenario of market prices and computing cash-flows arising from the operation of the plants. The distribution of the cash-flows is analyzed to produce a 90 and 95 cash-flow at risk measure for each plant
