Photovoltaic and wind power generation calculation

How are PV and wind power plants estimated?

The installed capacity (a) and costs (b) of PV and wind power plants built during 2020–2060 are estimated in our model by optimizing the construction time of individual power plants at a temporal interval of 5 years (bars) or 10 years (stars).

What is the power-use efficiency of PV and wind power plants?

By considering the flexible power load with UHV and energy storage, the power-use efficiency for PV and wind power plants is estimated when the electrification rate in 2060 increases from 0 to 20%, 40%, 60%, 80% and 100% (a) and the power generation by other renewables in 2060 increases from 0 to 2, 4, 6, 8 and 10 PWh year −1 (b).

What is the parameter estimation method for wind farms & photovoltaic power plants?

The parameter estimation method is generally used to obtain the probability distribution of the output of wind farms and photovoltaic power plants. However, the results of the parameter estimation method are not always satisfactory because there is often a significant gap between the selected parameter model and the actual physical model.

Can wind power and photovoltaic energy be correlated?

This type of research has only established correlation models that include a single wind and solar resource, without analysing the spatiotemporal correlation between wind power and photovoltaic, two new energy sources simultaneously.

What is the average lifetime of a PV & wind power plant?

We adopted a fixed ratio of O&M costs to investment costs for the projected PV and wind power plants 50, 51. We adopted 25 years (ref. 30) as the average lifetime of PV or wind power plants. We considered the costs of electricity transmission by UHV when increasing the installed capacity of a power plant.

What is the capacity of a wind farm and a photovoltaic power plant?

The capacity of the wind farm is 210 MW, and the capacity of the photovoltaic power plant is 50 MW. Considering the seasonal characteristics of output, the annual data will be grouped by month and the output of the wind farm and photovoltaic will be equivalent to one unit respectively. 4.1.
