[Equest-users] Solar PV Modeling in eQUEST

[Brian Fountain]

The energy for your PV/electric generator is reported in the PS-C and as a PS-H report in the .sim file.

When I double the size of your PV array, I see the PS-H AC output nearly doubling.  Note that the numbers shown below are for a different weather file (one I had pre-installed) so will not match yours.

I find it helpful to create a separate electric sale meter for the photovoltaics and put the generator on that meter.  That way, the PS-B explicitly shows the electricity from the PV array.

Hi Ahmad,

A few years ago, I came across the issue. As far as I know, the only way to check the electricity generated from solar PV systems is to use hourly reports under Project & Site.

1. Create a new report block.

2. Include the new block.

3. Run and find hsr file. Change the extension name of the hsr file to .csv.

4. Open it with Excel.

Hope it helps.

Hello Guys,

I have created Photovoltaic Module and Electric Generator under Utility but the electricity consumption and the electrical demand did not change. I changed the capacity of the solar PV system in many times but the consumption and the demand are not changing with the changes I do in the solar PV system. Anybody can help please? Am I missing something?

The .pd2 and .inp files are attached.

Regards

Ahmad
