Energyflexible Buildings through the control of cooling devices via unidirectional communication in Local Energy Communities

For the electricity system (especially to the distribution network), new challenges arise as a result of the rise in temperature due to climate change due to an increasing number of active cooling systems. Due to the high electrical power of the cooling units, which are sometimes operated in an uncoordinated manner, consumption peaks occur in the system.

The Cooling LEC project is developing and demonstrating a central control of decentralized active cooling systems via a further development of the unidirectional communication of ripple control systems. This creates energy-flexible buildings in the sense of a “Renewable Energy Community”.

The system offers u. a. the possibility of covering the demand for decentralized active cooling devices with locally available renewable energy (PV). Additional burdens on conventional communication channels and investments in decentralized controls are avoided.
