Levelized Cost of Energy of Wind Power System in Multi-Permeability Scenarios

To have power generation and consumption costs of high-proportion new energy power systems calculated, based on the traditional wind power levelized cost of energy(abbr. LCOE) model, firstly, a wind power system-levelized cost of energy model(abbr. S-LCOE) was constructed considering the auxiliary service costs caused by wind power integration and the low-carbon benefits of wind power, and a change relationship model of wind power installed capacity was established considering the permeability. Furthermore, the output sequence of wind power was used as the link to connect the two models. The minimum wind power installed capacity which meets the permeability requirement was set as the input parameter to quantify the cost of wind power generation in order to realize the power cost calculation of wind power systems under different permeability scenarios. Finally, by numerical analysis, the changes in the power consumption cost of wind power generation under four typical permeability scenarios were studied, and the curves of the S-LCOE of wind power considering different permeability were plotted. The results show that the change in wind power penetration has the greatest impact on peak shaving cost. The proposed model can be effectively used to calculate the cost of wind power generation under different permeability scenarios, and provides support for the reasonable planning and cost control of regional wind power integration.
