Query: A compositional modeling framework for the optimal energy management of
  a district network   This paper proposes a compositional modeling framework for the optimal energy
management of a district network. The focus is on cooling of buildings, which
can possibly share resources to the purpose of reducing maintenance costs and
using devices at their maximal efficiency. Components of the network are
described in terms of energy fluxes and combined via energy balance equations.
Disturbances are accounted for as well through their contribution in terms of
energy. Different district configurations can be built, and the dimension and
complexity of the resulting model will depend on the number and type of
components and on the adopted disturbance description. Control inputs are
available to efficiently operate and coordinate the district components, thus
enabling energy management strategies to minimize the electrical energy costs
or track some consumption profile agreed with the main grid operator.
