Optimal timing for power plant maintenance in the Electricity Reliability Council of Texas in a changing climate
We analyzed data for the Electricity Reliability Council of Texas (ERCOT) to
assess shoulder seasons -- that is, the 45 days of lowest total energy use and
peak demand in the spring and fall -- and whether their occurrence has changed
over time. Over the period 1996--2022, the shoulder seasons never started
earlier than late March nor later than mid-October, corresponding well with the
minimum of total degree days. In the temperature record 1959--2022, the minimum
in degree days in the spring moved earlier, from early March to early February,
and in the fall moved later, from early to mid-November. Warming temperatures
might cause these minima in degree days to merge into a single annual minimum
in December or January by the mid-2040s, a time when there is a non-trivial
risk of 1-day record energy use and peak demand from winter storms
Optimal Placement of Public Electric Vehicle Charging Stations Using Deep Reinforcement Learning
The placement of charging stations in areas with developing charging
infrastructure is a critical component of the future success of electric
vehicles (EVs). In Albany County in New York, the expected rise in the EV
population requires additional charging stations to maintain a sufficient level
of efficiency across the charging infrastructure. A novel application of
Reinforcement Learning (RL) is able to find optimal locations for new charging
stations given the predicted charging demand and current charging locations.
The most important factors that influence charging demand prediction include
the conterminous traffic density, EV registrations, and proximity to certain
types of public buildings. The proposed RL framework can be refined and applied
to cities across the world to optimize charging station placement.Comment: 25 pages with 12 figures. Shankar Padmanabhan and Aidan Petratos
