Abstract

In this paper the total installed load namely, the electrical load demand model for dynamic model of the electrical energy demand is provided. Based on this definition, electrical energy demand equals the product of the electrical installed power and the total time required for commissioning, while considering the simultaneous coefficient.
dEE(t)=UD(t).eD(t)

Where:
dEE(t) Is Demand for Electrical Energy in One Year (Gwh),eD(t) is Electrical Devices Installed [G.W] and UD(t) is Utilization Duration of the Devices [hours per year]. Therefore, identifying the eD(t) function or the load demand function by linear or non-linear methods, based on the principal parameters, and determining the main part of deciding factors, is given in this article. Linear models furnish identifying the effective exogenous factors in the model. Then the main model in the framework of non-linearity is given. Therefore, factors like energy prices, level of household income and production rate are shown to be effective in the model. In this study, statistical data of the past 33 years are made use of.
