The Scottish Scientist web-site in association with the Scottish Scientist Blog at WordPress.Com Wind, solar, storage and back-up system designerPeak demand, wind, solar and back-up power / energy usage and storage capacity calculatorFor the specification and design of renewable energy electricity generation systems which successfully smooth intermittent wind and solar generation to serve customer demand, 24 hours a day, 7 days a week and 52 weeks a year.Adopting the recommendations 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 and solar power to back-up power. The recommended energy storage capacity is about 90% of one day's average wind and solar energy generation. The tables' columns consist of adjustable power and energy variables. 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 and solar power generation Capacity Factor (C.F.) percentages can be adjusted too. The energy generation percentages from wind and solar power can be adjusted, either directly or according to the latitude of the system. 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. Caution! Your browser scripts must be allowed and enabled for the designer to work. All browser extension pop-up blockers, ad-blockers, Noscript etc either must be disabled while using the designer or the designer web-page must be trusted and white-listed, if the script-blocker extension even allows white-listing because some may not, in which case disable it. 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. |
