An Accurate Optimal Sizing Method of a Hybrid PV/Wind Energy Conversion System with Battery Storage
The present paper gives an accurate iterative methodology for optimal sizing of a hybrid photovoltaic/wind system with battery storage, using the concept of the loss of power supply probability and the total net present cost. In the first part, the optimum combinations that can meet the load demand while respecting the desired loss of power supply probability level are determinate, following two steps: First, all feasible solutions are determinate. Second, each feasible solution is optimized iteratively.In the second part, the optimal solution which has the lowest net present cost is selected based on an economical study. Lastly, the proposed and adopted methodology is verified and discussed with the meteorological data of the area of Hawaria (Tunisia) to prove its fast computation time and good convergence accuracy.
