Major Comments on WD 31 Specifications by Ed Cazalet
310 change Insert a period after Operator. Then follow with "ISOs provide ...
312 delete "that'
Delete 1st sentence on 332 (we say it again at 339) . Change the second sentence to read "the price or costs of transport may vary over time.
334 change Delivery cost to Transport costs
330: Change sentence beginning on 330 ti "Product Transport can be characterized by (1) the quantity transported and price, or (2) the quantity transported and cost detail.
361 change sentence beginning on 361 to read : "The Resource schema extends the Power schema to provide information on the capabilities and the responsiveness of devices and systems in support of decisions regarding tenders and transactions for products that can be provided or consumed by Resources.
403 : delete "for the market" as unnecessary.
386 delete " are often" and replace with " "may be"
1052 : delete ).
470 : As I have previously recommended, Autonomous is a characteristic of the interactions among the parties and in should not be in EMIX. (possibly in EI, for a example a thermostat that automatically responds to a priced tender.)
535: Last two rows need heavier lines like the rest of the table.
562 : Market Requirement is completely mis named these elements are elements of a tender or transaction and may be imposed by either or both sides in a bilateral transaction or by either or both sides or by a market in a market transaction..
647 : the term "internal sequence" is nowhere defined.
Use of the term "capability: is confusing. 1 is an unbound schedule operation of a resource.
Execution indicates you are executing the option of the tender. Should not refer to a "contract". Say 'Acceptance of the Tender results in a Transaction'. I would change the word 'Execution' to 'Acceptance' otherwise we confuse terminology for EMIX Tenders with terminology for EMIX Options.
669 Quantity Granularity could also be in Table 7-2
716 Title should be "Illustrative Diagram of Energy Item Types"
Market Granularity should be expressed in Table 3-5 EMIX Base along with Integral Only. It should be renamed Quantity Granularity.
Suggest Relabeling Table 5-3 as Resource Offer Terms and moving it to Resouce.xsd.
749 change sentence beginning on this line to: Common distinctions include:
749 change Duration to Interval
762: focuses too much on Transport Costs rather than Price.
Change section to read:
Product Transport provides for the transport of a product from one Interface location to another generally using transmission and distribution facilities. Transport prices may cover recovery of investment and energy loses incurred during transport as well as congestion prices. A single price may characterize a Transport Product or a set of charges. Product descriptions for Transport are discussed Section 11 Power Transport Product Description.
777 Table 10-1 and 10.e line 804
If Power Product Description assumes constant power (rate of delivery it is inconsistent with the requirements power products that it supports. I suggest an additional element in Power Product Description that is a Boolean (Constant power over the interval). It would be true for all TeMIX Products and false for all others so far defined. This can be explained in Table 10 -1.
Then we can drop section 10.5 as redundant to Section 12.
TeMIX Power Description change to
Used for transactions for energy delivered at a constant power (rate of delivery of energy) over an interval of a specified duration.
858 change cost to prices and costs
900 change subscribed to "transacted" also on 902 and 909 and 910 and 913
