Exception at live re-start

[bijwaard]

Hi Gerwin,

I get the following exception at start related to sunData, and sometimes also later. I merged the old ORTEP scripts using the sst sensor and model workspace with the most recent Demkit. In the ORTEP model the sunData is used to predict PV on both 3-phase and single-line inverters:

• pvc = LivePvCtrl("PVCTRL_3P_L"+str(i+1), pv, ctrl, sun, sim)
• pvc = LivePvCtrl("PVCTRL_SP_L3", pv, ctrl, sun, sim)

Kind regards,

I did some debugging, on the arguments of result.append and found the following, apparently self.maxProduction is empty, while it worked fine until 01:00 this morning after I started yesterday.

12:17:41 | WARNING: [PVCTRL_3P_L1] livePvCtrl model b=20 idx=0, len(model)=48, len(maxProduction)=0

Because of this, I now initialize self.maxProduction in livePvCtrl::startup() after self.bins is initialized.

	def startup(self):
		self.bins = int(86400/self.binSize) # 1 day = 86400 seconds
		self.maxProduction = [0] * self.bins

Apparently not all realized values are available after restarting demkit with live data, also had to change the following in loadCtrl::updatePrediction(self):

-						self.realized[c][time] = prediction[idx]
+						try:
+							self.realized[c][time] = prediction[idx]
+						except:
+							self.realized[c]={ time : prediction[idx] }

The mix-up may have appeared because I wrestled a bit with the ortep model while changing the measurements and prediction of the single-line inverter from L2 to L3.
