This paper presents artificial immune system for optimal scheduling of thermal plants in coordination with fixed head hydro units. Numerical results of two test systems have been presented to demonstrate the performance of the proposed algorithm. The results obtained from the proposed algorithm are compared with those obtained from differential evolution, particle swarm optimization and evolutionary programming technique. From numerical results, it is found that the proposed artificial immune system based approach is able to provide better solution than differential evolution, particle swarm optimization and evolutionary programming in terms of minimum cost and computation time. 相似文献

Power engineering education feeds the power engineering profession. If the profession is to continue to be a vital part of electrical engineering, something must be done about the educational stem. In some sense, power education is at a crossroads, and there is a need to take a positive growth path by moving the most pressing and difficult problems in power engineering to a viable high-tech power program. Such an educational program must center on systems, new materials, applications of advanced mathematics and physics, and the integration of economic principles. One potential avenue is to appeal to national governments worldwide to support power engineering research through university-based centers. An upsurge in student interest at the undergraduate level and the importance and complexity of typical power engineering problems are indicative of positive growth in the field; however, vigilance and increased industry participation in all educational sectors are needed to ensure vitality of the field. This article discusses various aspects of power engineering education including the power engineering curriculum, supply and demand for education, faculty careers, and alternative strategies for power engineering education. 相似文献

A review on the prediction of building energy consumption 总被引:1,自引:0,他引:1
The energy performance in buildings is influenced by many factors, such as ambient weather conditions, building structure and characteristics, the operation of sub-level components like lighting and HVAC systems, occupancy and their behavior. This complex situation makes it very difficult to accurately implement the prediction of building energy consumption. This paper reviews recently developed models for solving this problem, which include elaborate and simplified engineering methods, statistical methods and artificial intelligence methods. Previous research work concerning these models and relevant applications are introduced. Based on the analysis of previous work, further prospects are proposed for additional research reference. 相似文献
