Regolith thermal energy storage is a scheme for providing nighttime electric power to a lunar base1. It involves storing thermal energy in a pile of regolith1. The concept is based on the ability to store enough high temperature thermal energy within the lunar regolith during the daytime to allow for continuous power production throughout the night2. The stored heat could also be released directly to keep robotic equipment warm enough to function during the long hours of darkness3.

One way to achieve global optimal solutions is to incorporate a dynamic programming (DP) approach. This allows to evaluate the operation of a BESS and its use cases to set the benchmark for computationally inexpensive PFCSs applied online. In real applications, DP allows the planning of power distribution in EMS ahead of time.
