Curtailed Power from PV for frequency regulation #120

Open raselmahmud02 opened 5 years ago

@yliu250 @Hayden-Reeve

There is an internal fleet level variable for PV that keeps an extra headroom to modulate PV output for both under- and over frequency regulation. By default it is 20%, but you can change it following way:

fleet.FW_P_reserve=0.2

where fleet is PV fleet. However, this does not change PV base power which the maximum power point (MPP) of PV.

I tested AI-PV integration. It seems like the base power of PV is zero. So as the service power. I also tried to use a frequency increase to test PV response as we discussed last week. It is still the same result. Any clue on how to fix this issue?

@yliu250 - can you post your results and details. For example what time of day was the run executed? That can result in zero power.

@raselmahmud02 , is there a flag to set PV operating in reserve mode?

raselmahmud02 commented 5 years ago

@yliu250 - I agree with Hayden, we need to look in to the time. PV power is available only when there is sun. A zero base power suggests that the service is being requested probably at night.

@Hayden-Reeve, currently there is no flag to set the PV in reserve mode. And this mode is available only for frequency-watt function. However, as I mentioned earlier, it can be turned off by setting _FW_Preserve = 0. for other functions, there is no reserve mode of PV operation.

@raselmahmud02 @hayden-reeve Hi Rasel and Hayden, you are right. Let me change the start time of the service and try again.
