Electrical Capacity Optimization and Determination of the Economic Parameters in the Plan Installation of DG Generators in CNG Stations

In this article، for the option installation DG generators in CNG stations، the optimum electrical capacity and corresponding economical parameters are determined، according to maximize net present worth. In addition، the sensitivity relative to various parameters is investigated. The present study takes into consideration not only the constraint of maximum possible value of investment but also those constraints relative to proper power flow and accepted fault levels in the power grid. A new approach which simultaneously takes into account the electrical load profile and the power bills has been adopted in the modeling. consumed electrical load profile of CNG station under study located in Tehran، during one day period، has been extracted through a Power Harmonics Analyser device.
