Plugins:
- Revamp the battery plugin: rewrite completely the API, for a better usability.
The examples were updated accordingly.
+ - Add chiller plugin: enable the management of chillers consuming electrical energy
+ to compensate heat generated by hosts.

+
+/** @defgroup plugin_chiller Plugin Chiller
+
+ @beginrst
+
+This is the chiller plugin, enabling management of chillers.
+
+Chiller
+....................
+
+A chiller is placed inside a room with several machines. The role of the chiller is to keep the temperature of the room
+below a threshold. This plugin and its equations are based on the paper "Co-simulation of FMUs and Distributed
+Applications with SimGrid" by Camus et al. (https://hal.science/hal-01762540).
+
+The heat generated inside the room :math:`Q_{room}` depends on the heat from the machines :math:`Q_{machines}` and
+from the heat of the other devices, such as lighing, accounted using a factor :math:`\alpha` such as:
+
+.. math::
+
+ Q_{room} = (1 + \alpha) \times Q_{machines}
+
+This energy heats the input temperature :math:`T_{in}` and gives an output temperature :math:`T_{out}` based on the the
+mass of air inside the room :math:`m_{air}` and its specific heat :math:`C_{p}`:
+
+.. math::
+
+ T_{out} = T_{in} + {Q_{room} \over m_{air} \times C_{p}}
+
+If the output temperature is above the goal temperature :math:`T_{goal}` the chiller compensates the excessive heat
+using electrical energy :math:`Q_{cooling}` depending on its cooling efficiency :math:`\eta_{cooling}` :
+
+.. math::
+
+ Q_{cooling} = (T_{out} - T_{goal}) \times m_{air} \times C_{p} / \eta_{cooling}
+
+The chiller has a power threshold that cannot be exceeded. If the power needed is above this threshold, or if the
+chiller is not active, the temperature of the room increases.
