Improved Real-Coded Genetic Algorithm Solution for Unit Commitment Problem Considering Energy Saving and Emission Reduction Demands

Unit commitment(UC), as a typical optimization problem in electric power system, faces new challenges as energy saving and emission reduction get more and more important in the way to a more environmentally friendly society. To meet these challenges, we propose a UC model considering energy saving and emission reduction. By using real-number coding method, swap-window and hill-climbing operators, we present an improved real-coded genetic algorithm(IRGA) for UC. Compared with other algorithms approach to the proposed UC problem, the IRGA solution shows an improvement in effectiveness and computational time.     

车辆发动机缸套—活塞环磨损试验研究

为了实现对车辆发动机缸套—活塞环磨损失效分析和仿真计算,以缸套—活塞环摩擦副为研究对象,制作与缸套—活塞环相同材料的磨损试样,采用拉丁超立方法设计了模拟缸套上止点附近磨损的8组不同压力与速度的试样磨损试验。依据磨损试验数据,分析了缸套试样的磨损质量和磨损率的变化过程;通过试样表面电镜扫描,分析了缸套试样不同磨损阶段的表面形貌特征;采用响应面拟合方法,建立了不同工况下Archard黏着磨损模型中磨损系数K的计算公式,为发动机缸套—活塞环磨损仿真计算提供基础。
