Day‐ahead optimal scheduling of building energy microgrids based on time‐varying virtual energy storage

open access: yesIET Renewable Power Generation, 2023
The thermal inertia of a building envelope endows a building with a heat storage capability, introducing scheduling flexibility to a building energy microgrid (BEM). The flexibility is usually modelled as virtual energy storage (VES) and used to optimize
