The 2020 Power Trading Agent Competition

摘要
This is the specification for the Power Trading Agent Competition for 2020 (Power TAC 2020).
Power TAC is a competitive simulation that models a “liberalized” retail electrical energy market,
where competing business entities or “brokers” offer energy services to customers through tariff
contracts, and must then serve those customers by trading in a wholesale market. Brokers are
challenged to maximize their profits by buying and selling energy in the wholesale and retail
markets, subject to fixed costs and constraints; the winner of an individual “game” is the broker
with the highest bank balance at the end of a simulation run. Costs include fees for publication and
withdrawal of tariffs, for rectifying supply-demand imbalances, for contributions to peak demand,
and for customer connections.
The simulation environment models a wholesale market, a regulated distribution utility,
and a population of energy customers, situated in a real location on Earth during a specific period
for which weather data is available. The wholesale market is a relatively simple call market,
similar to many existing wholesale electric power markets, such as Nord Pool in Scandinavia or
FERC markets in North America, but unlike the FERC markets we are modeling a single region,
and therefore we approximate the effects of locational-marginal pricing through manipulation of
the wholesale supply curve. Customer models include households, electric vehicles, and a variety
of commercial and industrial entities, many of whom have production capacity such as solar
panels or wind turbines. All have “real-time” metering to support allocation of their hourly
supply and demand to their subscribed brokers, and all are approximate utility maximizers with
respect to tariff selection, although the factors making up their utility functions may include
aversion to change and complexity that can retard uptake of marginally better tariff offers. A
distribution utility models the regulated natural monopoly that owns the regional distribution
network, and is responsible for maintenance of its infrastructure. Real-time balancing of supply
and demand is managed by a market-based mechanism that uses economic incentives to encourage
brokers to achieve balance within their portfolios of tariff subscribers and wholesale market posi-
tions, in the face of stochastic customer behaviors and weather-dependent renewable energy sources.
Changes for 2020 are focused on stability and on making customer evaluation of regulation
rates more realistic, and are highlighted by change bars in the margins. See Section 4.1.1 for
details.
