Future Energy Management in Fuzzy Environment A possibility model

Energy and energy management is one of the most important subjects which concerns all the countries all over the world. As fossil fuels getting replicated, attention toward other energy sources increases. Renewable Energy Sources (RES) have become one of the popular topics in this field. Although these sources are renewable by nature, several difficulties are faced when countries attempt to implement these systems. One of these problems is the changing efficiency of RES due to availability and quality of sources like sunlight intensity or wind speed. This study considers various renewable energy sources and various needs in a country. Next, a linear programming (LP) model is used to optimize the problem in deterministic form. After that, because efficiency of RES is not deterministic, in this paper we use fuzzy linear programming to handle these difficulties. To achieve this, we transform our LP to FLP using theorems from literature. In this study, we used six RES plus nuclear energy to meet electricity demand. In the end to test our FLP model, a case study in Iran, which bifurcates this country to east and west sections, each with different potentials, is done and the results are presented.
