[BLDG-SIM] Clarification: Hourly electrical utility report

[Steve Gates]

In DOE-2.2, you can easily access hourly electrical data via the hourly-report for the ELEC-METER(s).

In the more recent 2.2 releases, you can directly simulate PV systems, including sellback.  However, there may be a problem if you use the Sandia/King formulation, as apparently the number of coefficients have increased since the algorithm was inplemented.  

Does anyone have a concise document summarizing the current usage of coefficients in the Sandia/King photovoltaic algorithm?

  Subject: [BLDG-SIM] Clarification: Hourly electrical utility report


  I have a number of questions regarding what I was looking for in my earlier email.  I thought I should clarify why I am asking for advice:  I actually need hourly reports to verify the metered building electrical energy versus the amount of electrical energy generated by building mounted photovoltaics.  I need to determine what percentage of the yield from the PV system is in excess of the total building load at any point during the year.  In my building, if the yield is greater than the load, then corresponding amount of electricity in kWh will be "net-metered" or reverse metered to the grid.  Since we will be developing an hour-by -hour model of the PV yield, I need a whole building energy end use-report to match.  The ultimate goal will be to predict the amount of energy sold back to the utility.  I know that I have total operating hours and demand kW in other reports.  In summary, that's why I need an hour-by-hour report.

  Thanks again,
