Peak demand, wind and back-up power / energy usage and storage capacity calculator
For the specification and design of renewable energy electricity generation systems which successfully smooth intermittent wind generation to serve customer demand, 24 hours a day, 7 days a week and 52 weeks a year.
Adopting the recommendation derived from scientific computer modelling, the tables offer rows of previously successful modelled system configurations – row A, a configuration with no back-up power and rows B to H offering alternative ratios of wind power to back-up power.
The recommended energy storage capacity is about 90% of one day’s average wind energy generation.
A cell value can be adjusted according to the design criteria and then all the other table values will be recalculated, spreadsheet-style.
The wind power generation Capacity Factor (C.F.) percentage can be adjusted too.
A configuration text page for a row which has been adjusted and designed satisfactorily can be opened for text output by clicking on the row’s “TXT” icon in the “Open text page” column.
The recommendations derived from modelling are only specified to 2 significant figures so take with a pinch of salt any apparently third “significant” figures in the numbers output in the configuration text pages.
