Thermal Energy Storage (TES) - large scale
=======================================

The TES technology represents a large scale thermal energy Storage
connected to the district heating network. It can be charged by all 
the technologies that are defined via the connections parameters in
the input file. The thermal energy storage is modelled as a simple
thermal battery. It has a given maximum capacity that can be set
by the optimizer if optimization is activated. When charging and
discharging, a fixed loss rate is applied. Furthermore, the storage
loses energy at a constant rate. The heat stored in the TES is 
assumed to be useful heat that can be directly used in the district
heating network. 

Using the parameter force_asynchronous_prod_con, the optimizer can be 
forced to never charge and discharge the storage at the same time.
This can be useful to prevent the energy system from disposing of 
thermal energy using the charging and discharging losses of the 
storage.

The initial charge of the storage is usually set to be optimized. Then,
the constraint is that the initial and final storage level have to be 
equal. Alternatively, a fixed initial state of charge can be defined.
