Proccedings of the 21st International Conference on Electricity Distribution CIRED
The Energy Research Alliance of Lower Saxony (FEN) has developed the grid-oriented operating method of combined- heat-and-power (CHP) micro units for the domestic energy supply. With this mode of operation, it is possible to adapt the power-supply of the distributed generators to the load profile of the low voltage system. There is also a decoupling of the heating supply and the power generation by a thermal storage tank.
Via a communication interface according to the international standard IEC 61850, the CHP micro unit will be controlled through the internet and thus from everywhere. In a field test with two units, the grid-oriented operating method will be tested for one year. The field test started with the beginning of 2011 in two multi-family houses of a regional building society. The Operation of the power plants happens by an intelligent power generation plan. This plan is created from measurement values of the local installation by a mainframe computer. There, the values are revised and transmitted to the CHP micro units.
