This paper explains the concept of a distributed integrated energy management (diEM) system for residential buildings. The overall goal of the system is to minimize energy economic costs of the household. This is obtained by load shifting in order to enhance the self-consumption rate of the on-site renewable electricity production. The crucial difference, in contrast to a centralized energy management (where data from household devices must be gathered and evaluated centrally), is the presence of multiple smart energy managers that have to negotiate with each other on switch-on times of their dedicated electric devices. The basic procedure of the diEM is divided into a discovering phase, where managers discover how many further managers are involved, and a negotiation phase. Best practice parameter settings are deduced from realistic scenarios. Runtime results show that this system can keep pace with central systems and a mayor advantage is its robustness against failure of individual energy managers.     «
