using the proposed planning method. The results of
the given scenario show that the presented approach
can be applied to a fleet size of 5000 houses.
6.2 Recommendations
In future work scalability should be validated; is it
possible to solve an extended scenario, where multi-
ple fleets are optimized simultaneously? Regarding
this extended scenario, the fleet sizes should be ana-
lyzed for their contribution to the high level optimiza-
tion problem and the speed and quality of the under-
lying lower level optimization problem(s). In this ex-
tended scenario, the influence of the production ca-
pacity of low level generators on the capability to ad-
just the total output as a fleet also has to be studied.
Also demand side load management should be
added, as well as other local generation or storage
technologies, such as solar cells and heat pumps, to
solve an extended real life Multilevel Unit Commit-
ment Problem. Other types of local generation, de-
mand side load management and local storage can
be incorporated in a similar way as is done for the
microCHP. However, these possibilities cannot be
treated as independent fleets. An additional level
needs to be introduced in the MUCP, where the in-
teractions between these possibilities are considered
as a new type of combined patterns.
