Algorithms for Balancing Demand-Side Load and Micro-Generation in Islanded Operation

Micro-generators are devices installed in houses producing electricity at kilowatt level. These appliances can increase energy efficiency significantly, especially when their runtime is optimized. During power outages micro-generators can supply critical systems and decrease discomfort. In this paper a model of the domestic electricity infrastructure of a house is derived and first versions of algorithms for load/generation balancing during a power cut are developed. In this context a microCHP device, producing heat and electricity at the same time with a high efficiency, is used as micro-generator. The model and the algorithms are incorporated in a simulator, which is used to study the effect of the algorithms for load/generation balancing. The results show that with some extra hardware all appliances in a house can be supplied, however not always at the preferred time.
