Cory, the power output of each component in your load should go to an equation that sums them together. That offers you the flexibility to include (or exclude) whatever aspects of the system you want from the load that is being taken care of by a particular source (pv, grid, wind, etc.) Best, David On 3/9/2011 13:35, Cory Duggin wrote: What is the best way to calculate the overall electrical usage for the entire system in my simulation? I know there is a utility schedule component, but it takes a single load input. How do I combine all of the power outputs from all the components involved to a single electrical load? Is there a type that already does this? -- *************************** David BRADLEY Principal Thermal Energy Systems Specialists, LLC 22 North Carroll Street - suite 370 Madison, WI 53703 USA P:+1.608.274.2577 F:+1.608.278.1475 d.bradley@tess-inc.com http://www.tess-inc.com http://www.trnsys.com |
