简介:由瓦茨与Strogatz,的小世界网络研究激发了这篇论文在电力格子学习在拓扑学和串联线停止之间的关系。当传播网络是拥挤的时,串联线停止是串联能发生在力量格子的倒塌的一种类型。它被格子决裂跟随的线停止的一个自立的序列描绘,它通常导致普遍停电。这个工作的主要调查结果是双重的:一方面,工作建议有在他们的互联拓扑学的更多的混乱的拓扑学趋于关于在能定期比更多支持更大的产生和要求层次的意义串联线停止柔韧interconnectedtopologies.On另外的手,工作建议有更多的混乱的拓扑学趋于更易碎因为串联应该开始,他们趋于比更定期互连的拓扑学在更少停止以后分开碎。因此,在另外的复杂网络被观察了,看起来是在坚韧性和脆弱之间的折衷。这些结果用综合地产生的力量格子拓扑学被建立并且验证了使用IEEE57公共汽车和188公共汽车力量格子测试用例。

简介:在多客观的优化,交易分析在决定大多数比较喜欢答案起一个重要作用。这篇论文基于代理人价值交易函数论述明确的交互交易分析决定最好损害的解决方案。在themultiobjective框架,热电源派遣问题在四目的viz.cost,NO_X排放,SO_X排放和CO_X排放同时在哪个被最小化被承担。交互过程被以系统的方式调整目的相对重量用一个weighting方法实现。因此weighting方法便于在非劣等的领域模仿在冲突目的之间的交易关系。存取不在乎乐队,的利用模糊决策理论和决定制造者的相互作用worthtrade离开经由代理人被获得(SWT)目的工作。代理人价值交易函数在功能的空格被构造然后转变了成决定空格,因此代理人worthtrade离开目的工作通过最佳的重量模式联系决定制造者的偏爱到非劣等的解决方案。热力量派遣问题的最佳的答案被认为真实、反应的力量是损失获得。Decoupled负担流动分析被执行发现传播损失。建议方法的有效性在11公共汽车上被表明,17线IEEEsystem,三个发电机包括。

简介:当时,这篇论文论述在承诺的产生单位之中决定力量需求的分配的方法论象会一样最小化目的数字物理;技术系统限制。过程认为二是在他们的目标的相关性之上基于活跃力量或反应发电的decoupled问题。两个都,这些问题顺序被解决了完成最佳的分配活跃;反应发电当时最小化操作花费的、气体的污染物质排放目的;有与发电机一起操作限制的系统的考虑的活跃力量传播损失禁止了操作地区;传播线流动限制。活跃;反应力量线流动在概括产生移动分发因素(GGDF)的帮助下被获得;分别地概括了Z公共汽车分发因素(GZBDF)。当采用weighting方法时,第一个问题在分到目的最好的重量是坚定的多客观的在框架被解决;处于第二个问题,系统的活跃力量损失是到系统限制的最小化的题目。建议方法的有效性在30公共汽车IEEE力量系统上被表明。
简介:大、复杂的建设从各种各样的来源投射脸风险,如此的工程的成功的结束取决于有效风险管理。这研究调查参予在中国构造AP1000核电厂的中国公司面对的风险。AP1000核反应堆是新的,产生III+反应堆由Westinghouse并且到设计了在中国首先被造。半结构化的会见途径被用来从在中国涉及AP1000工程的专家得到信息。基于会见,风险的各种各样的来源被识别。通常除了将军冒险那megaprojects脸,有唯一的风险,从象工艺、政治、组织上、单个的人员风险那样的各种各样的来源产生。风险管理策略被建议管理在学习识别的一般、唯一的风险。这研究的调查结果将对涉及AP1000核电厂的构造减轻与工程联系的风险的中国公司有用。
简介:批评基础结构正在变得对串联失败逐渐地相互依赖、脆弱。存在研究分析了相互依赖的网络的危险到从网络拓扑学结构的静态的观点串联失败。这份报纸开发在力量网络认为负担的动态再分配探索相互依赖的力量水网络的危险的一个更现实主义的串联失败模型。在这个模型,批评忍耐阀值原来被建议显示网络的危险到串联失败。另外,是重要的联网危险的一些关键参数通过数字模拟被识别并且确定。当忍耐参数的值在批评忍耐阀值上面时,结果证明串联失败能被阻止。否则相互依赖的网络在攻击力量节点的批评部分以后崩溃。相互依赖的网络随互相依赖力量的增加变得更脆弱,它暗示保护那些互连的节点减少串联失败的后果的重要性。相互依赖的网络在高负担的攻击下面是很脆弱的,它显示出保护高负担的节点的意义。
