Improved framework for techno-economical optimization of wind energy production

This paper presents an improved framework for the techno-economical optimization and analysis of wind energy production. The main objectives are the maximization of the wind energy production and the minimization of the Levelized Cost of Energy (LCOE). The energy production maximization is achieved through optimal site matching of wind turbine generators. Comparative and improved analyses of various models for the optimal matching process and its associated performance indicators are presented. In addition, an improved model for estimating the wind energy production is adopted. Numerical demonstrations are presented considering a set of selected sites in Egypt. These sites cover all the Battelle-Pacific Northwest Laboratory (PNL) classes of wind resources. In addition, careful inspection of the PNL classification discrepancies is presented. Based on energy production, the best site matching index is determined for various wind resources. In addition, the LCOE is estimated considering various indicators, financial, and technical inputs. Measures for reducing the LCOE are determined based on a sensitivity analysis. The external costs of energy have been considered in estimating the LCOE and evaluating the grid parity. In addition, a grid parity analysis is presented considering various load sectors and debt ratios. The main outcomes are summarized in the conclusions' section.
