Fast Regulation Data Explanation To accompany file "Fast Regulation Signal Data.csv" This describes the PJM signal for fast regulation, captured from a regulation resource (in PJM terms, "REG-D"). It is available from the UD V2G Web site, along with an accompanying file for slow regulation. Fast regulation resources are scored by PJM based in part on how they respond to the PJM regulation signal. They receive a higher score if they respond more quickly and more accurately, and payment is proportional to the score. If they do not meet the minimum score, they cannot participate in the fast regulation market. Approximately, these are resources responding within 10s of seconds, not minutes. The accompanying file was captured by the University of Delaware aggregator in spring 2013, as part of our operation of electric vehicles serving as a power plant on the PJM market. Specifically, it runs between 2013/4/1 and 2013/4/15 inclusive. The file is "csv" has two columns, separated by a comma. The first column is a time count in seconds since the start of the file. The second column (separated by a coma) is the regulation signal normalized to the range of -1:+1. Thus, if 10 kW were offered, +1 would be a request from PJM to discharge at 10 kW, whereas -0.5 would be a request to charge at 5 kW. In processing this file, note that only seconds are included during which we were in the market. This week was during shakeout and testing, operated mostly at day--there are many hours for which we were not processing the PJM signal. For most purposes, for example tabulating deviations from 0, the second count can be ignored and the file treated as a continuous record. If you want to actually know the sequence, you can scan for gaps in the second record, and only analyze continuous sequences. Last updated June 2013 by Willett Kempton
