Hybrid power plant financial model to estimate the overall profitability of the hybrid power plant. It considers different weighted average costs of capital (WACC) for wind, PV and battery. The model calculates the yearly cashflow as a function of the average revenue over the year, the tax rate and WACC after tax ( = weighted sum of the wind, solar, battery, and electrical infrastracture WACC). Net present value (NPV) and levelized cost of energy (LCOE) is then be calculated using the calculates WACC as the discount rate, as well as the internal rate of return (IRR).
- setup_partials()[source]
Declare partials.
This is meant to be overridden by component classes. All partials should be declared here since this is called after all size/shape information is known for all variables.
- compute(inputs, outputs)[source]
Calculating the financial metrics of the hybrid power plant project.
