Abstract
|
Nowadays, cases such as restructuring, environmental issues, difficulties and restrictions in the construction of new transmission lines, reducing losses, lack of dependence on fossil fuels, increasing power quality and involving the private sector in production cause the increasing entry of distributed generation systems. Purpose: the purpose of this study is to analyze the sector of the economic and environmental load in order to increase reliability in the presence of renewable resources. Method: the method of this study is descriptive-analytic. In this method, in addition to the imagery of whatever in the research, we also explain and describe the questions and the issues and dimensions in the research. Result: the tendency to use renewable distributed generation systems is increased with the considerable growth of load and the different restrictions of using fossil energy resources. Distributed generation units, according to technology specifications and the location of grid connection, can have positive effects on the power system such as improving the reliability of distribution grids, reducing the loading from feeders and super-distribution posts, and increasing the reliability of the system.
