+
+This module implements logic to distribute power to energy nodes based on
+energy requests.
+One of its central ideas is to represent the energy system for which power is
+distributed as an energy tree containing energy nodes.
+This enables the representation of arbitrarily complex configurations of
+physical and logical components within the targeted energy system.
+
+Please see :doc:`Energy Management in EVerest </explanation/energymanagement/index>`
+for a detailed explanation of the concepts behind this module.
