Using the growth models for optimization of energy distribution systems

Abstract

Energy distribution systems were developed in the recent years due to increasing population, new technologies and load demand. Alternative technical arrangements are made trouble to choose the best construction. On the other hand, system costs are affected for the new design and operating. That is, for a new distribution design or operation of an exist system, both technical and economical constraints must be consider. Today, the present planning is done more sensitively using various statistical methods and computer aided approaches depending on the new technology developments. Some parameters depend on system design must be considered correctly. If some of them change yearly, these changes must be included in the calculations such as load, inflation, etc. If this work is not done, then the system design may be insufficient. For example, if load growth is not considered correctly, then the system design will be affected from this situation because of operating losses. The purpose of this paper is a brief summary of reference [1]. Annual growth factors of load, loss factor and energy costs were considered to obtain the sufficient system design. So, all the cost expressions depend on these factors can be obtained correctly. Moreover, these factors were modeled in twenty-seven cases by the considered three models in "Present Worth Analysis" formulations. These cases can be used in such as exact cost expressions, optimum system design, selection of the optimum design amongst the others [2,3,4,5,6], etc. in energy distribution systems.
