Customer Services - RTP Customer's Optimization Function
Contents
The RTP system provides the RTP schedule
through email, pager, bulletin board or direct transfer. The RTP
operator at for the customer must enter the schedule into the
building automation software (BAS) and perform the necessary
optimization activities to implement the RTP goals. Note that EMS
or Energy Management System is often used interchangeably with
BAS.
The Energy Services Provider (Energy Service
Provider) obtains the Base RTP data tables from the Market Interface
Server, and uses them to develop Customer-specific RTP rate tables.
These calculations are based on contractual agreements between the
Energy Service Provider and the different types of customers it
serves. For example, a large industrial customer that can curtail
large loads during peak hours will get a different rate than a small
commercial customer with less ability to modify its load. The Energy
Service Provider sends these Customer-specific RTP rate tables to each
of the customers it serves, using different mechanisms: fax, email, or
direct data channels (e.g. dial-up telephone or AMR system).
The customer’s Building Automation System (BAS)
optimizes its loads and distributed energy resources (DER), based on
the customer-specific rate table it receives, the load requirements
and constraints, and any DER requirements, capabilities, and
constraints. The BAS understands the nature and opportunity for
altering consumption based on economic and comfort drivers, and, the
physical dynamics of the specific customer premises. The BAS then
issues (or updates existing) schedules and other control mechanisms
for loads and for DER generation. These control actions may be
automatically implemented or may be reviewed and changed by the
customer. The Customer’s BAS may then send generation schedules to the
DER management system for it to implement during each “settlement”
period. Note that the BAS may be a human as apposed to a software
system.
The BAS system uses the site-optimized algorithms
to forecast its load and DER generation. It also determines what
additional ancillary services it could offer, such as increased DER
generation or emergency load reduction, and calculates what bid prices
to offer these ancillary services at. The BAS then submits these
energy schedules and ancillary services bids to the Energy Service
Provider (or Scheduling Coordinator, depending upon market structure),
as input to the RTO/ISO market operations.
