Fuzzy Method in Feasibility Study of Using Biomass Solar Hybrid Source and Photovoltaic System for Designing a Research Center Building in Smart Grid of Hamedan

In this paper, the electrical consumption of a Research Center Building is derived of the bills, Then with defining of fuzzy Bus Thermal Coefficient objective function for heating, the amount of available heat selling to Research Center Building consumer that is produced by Biomass Solar Hybrid Source is calculated. With the capacity determination of Biomass Solar Hybrid Source to provide Thermal and electrical energy of Research Center Building and calculation of photovoltaic systems to supplying electrical energy, each technical calculation is presented. Then, Economic Calculation of each project will be addressed separately. The Economic optimization in designing and operation of electrical systems is usually done through a review of investment criteria, that in this study, are include: Net present value (NPV), Internal Rate of Return (IRR) and Return period (PP) that with regard to the economic evaluation methods, the economic evaluation of project is doing. The economic calculation shows that the use of Biomass Solar Hybrid Source is adequate but using of photovoltaic system is not adequate.
