Abstract:
The present paper develops a model to optimize the
daily operation of a hybrid energy system consisting of a
photovoltaic unit, a wind unit, a pumped hydro storage system and
a diesel generator. The main purpose of the developed model is to
minimize the hybrid system’s operation cost while optimizing the
system’s power flow considering the different component’s
operational constraints. The simulations have been performed
using “fmincon” implemented in Matlab. The model has been
applied to two test examples; the simulation results are analyzed
and compared to the case where the diesel generator is used alone
to supply the given load demand. The results show that using the
developed control model, fuel saving can be achieved compared to
the case where the diesel is used alone to supply the same load
patters.
