A Novel Approach for Generation Expansion Planning Based on Fuzzy-Analytical Hierarchy Process (FAHP)

Due to growing demand of the electric energy, the need to generation expansion planning is inevitable. In this paper at first effective criteria in Generation Expansion Planning (GEP) are determined and a novel approach for GEP is proposed. In this approach Fuzzy-Analytical Hierarchy Process (FAHP) is utilized for GEP. The Fuzzy is one of the techniques that uses for weight assessment in decision making in Multi Criteria Decision Making (MCDM) model. For this purpose, five criteria are introduced and then by utilization of the FAHP, the optimization of GEP problem is implemented. In the first stage, the Local Marginal Price (LMP) of each bus is calculated by Optimal Power Flow (OPF) execution. In the next stage, base on the criteria that will describe, the candidate places for power plants installation are determined. Finally, the FAHP is used to assign a value to each criterion and by using these values the optimal place for installation of power plant among the candidate places is determined. The IEEE 14 bus network is used to simulate and evaluate the effectiveness of the proposed method.
