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. Platform: |

Description: 优秀论论及对应源码。电力系统配电网的无功优化规划是保证配电网安全、经济运行的一项有效手段，是降低网损、提高电压质量的重要措施。因此，电力系统配电网无功优化规划问题的研究，既具有理论意义，又具有工程实际应用价值。配电系统最优规划问题是一个复杂的非线性组合优化问题，至今未得到很好的解决。Tabu搜索(TS—Tabu search)算法是近年来出现的用于求解组合优化问题的一种高效的启发式搜索技术。本文采用固定并联电容器作为研究对象对系统进行无功补偿，并利用智能优化方法得到使配电网损耗降低最大对应的最优节点解。并在补偿容量的邻域搜索方面做了改进，采用扩大邻域搜索范围以达到全局最优的效果。用IEEE的两个算例得出的计算结果证明了这种方法的可行性。-Excellent deals on the corresponding source code.

Description: 注水算法是根据某种准则，并根据信道状况对发送功率进行自适应分配，通常是信道状况好的时刻，多分配功率，信道差的时候，少分配功率，从而最大化传输速率。本文运用matlab通过对注水算法在mino系统中的三种不同的情况下进行了仿真，比较出在小信噪比时，相同信噪比下利用CSI的功率注水算法获得容量优于未知CSI的平均功率分配算法；相同容量下已知CSI信噪比比未知CSI时的信噪比小3dB.当信噪比增大到一定程度时，功率注水算法所获得的信道容量将收敛到平均功率分配的信道容量。-Water flooding algorithm is based on certain standards, and according to the channel condition to adaptive allocation of sending power, usually is a good moment, channel situation more distribution power, channel is poor, less power distribution, so as to maximize the transmission rate. This paper USES matlab based on water flooding algorithm in Austin system of three different cases are simulated and compared in small SNR, under the same SNR use CSI power allocation algorithm for capacity is superior to the average power allocation algorithm of unknown CSI Same capacity known CSI signal-to-noise ratio than the unknown CSI small signal-to-noise ratio of 3 db. When the signal-to-noise ratio increases to a certain degree, the power allocation algorithm for channel capacity will converge to the average power distribution channel capacity.

Description: This paper presents a new method to solve the network reconfiguration problem in the presence of distributed generation (DG) with an objective of minimizing real power loss and improving voltage profile in distribution system. A meta heuristic Harmony Search Algorithm (HSA) is used to simultaneously reconfigure and identify the optimal locations for installation of DG units in a distribution network. Sensitivity analysis is used to identify optimal locations for installation of DG units. Different scenarios of DG placement and reconfiguration of network are considered to study the performance of the proposed method. The constraints of voltage and branch current carrying capacity are included in the uation of the objective function. The method has been tested on 33-bus and 69-bus radial distribution systems at three different load levels to demonstrate the performance and effectiveness of the proposed method. The results obtained are encouraging. (2014-11-17 Platform: |

Description: 层次分析法，简称AHP，是指将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。该方法是美国运筹学家匹茨堡大学教授萨蒂于20世纪70年代初，在为美国国防部研究"根据各个工业部门对国家福利的贡献大小而进行电力分配"课题时，应用网络系统理论和多目标综合评价方法，提出的一种层次权重决策分析方法。该文件中包含了使用MATLAB来实现层次分析法的代码。(Analytic hierarchy process (AHP) is a decision-making method that decomposes the elements that are always related to decision-making into objectives, criteria, schemes and other levels, on which qualitative and quantitative analysis are carried out. In the early 1970s, Sarti, a professor of the University of Pittsburgh, an American operational research scientist, applied the network system theory and the multi-objective comprehensive evaluation method to the research of "power distribution according to the contribution of various industrial sectors to the national welfare" for the US Department of defense, and proposed a hierarchical weight decision analysis method.
