712 Watt-VAr: Open loop response time is missing? #227

Closed FW22 closed 1 year ago

FW22 commented 2 years ago

The interoperability requirements for the Watt-VAr-curve in IEEE1547 point to two different locations. image

First, it points to all parameters in chapter 5.3.4: image

Second, it points to a table that contains the curve points of chapter 5.3.4, adds the enable-switch and excludes the open loop response time: image

Open loop response time is included in model 705 (Volt-VAr), 706 (Volt-Watt) and 711 (Frequency-Droop), but not in 712 (Watt-VAr).

Is this a mistake or a conscious decision?

I'm running in this issue too.

I looked inside the profile worksheet of IEEE 1547.1-2020 and the Open Loop Response Time exists there. https://standards.ieee.org/standard/1547_1-2020.html

Table 32 points to Table 9 rather than Table 10. Table 9 contains the points for watt-var which do not include an open loop response time. Table 10 is the volt-watt function which does contain an open loop response time.

The open loop response time contained in the IEEE profile worksheet for watt-var (QP_ORLT_xxx) is a mistake in the worksheet and is not supported by the contents in 1547-2018.
