At TUT, the education of the health questions of electric and magnetic fields has been integrated into part of four courses, which also include other environmental issues. TUT also products two times per year situation report bulletins on medical-oriented studies related to electric and magnetic fields so that graduates and people working in transmission line projects can follow new studies of the area. It is important to develop more education of EMF health questions, so people can more easily understand how new devices and technologies work.展开更多

A lot of matters and knowledge need to be studied before the idea of deregulation can be implemented. Theoretically, it is said that deregulation can make a large impact to increase efficiency and encourage the competitiveness among related parties. However, to implement the concept of deregulation to electric power supply is very tough challenge. In deregulation environment, regardless of market structure, to know the transmission usage allocation is vital and very a complex problem. Thus, a lot of algorithms have been proposed to overcome it. This paper intends to solve the transmission usage allocation problem using optimization approach. The optimization tool that will be utilized is Genetic Algorithm （GA）. GA is probabilistic search technique that has its roots in the principle of genetics and strives for survival. In addition, GA is very robust. Since the nonlinear nature of power flow, it is expected that GA can give optimize results that equitable and acceptable. In this paper, 4-bus and Klos-Kerner 11-bus systems are used for analysis studies. Comparison with other method is also given in this paper.展开更多
