Abstract:
This paper investigates the operation of different demand
sector such as residential, commercial and industrial load profiles
when supplied with a grid tied micro-hydrokinetic pumped-hydro
storage (MHK-PHS) hybrid system. The aim is to explore the demand
sector which is more favorable to the proposed grid-tied MHK-PHS
hybrid system under the time-of-use (TOU) tariff scheme. Hence, the
optimum configuration of the proposed MHK-PHS hybrid system is
determined in order to investigate the effect of each demand sector on
sizing and operation of the hybrid system. HOMER Pro Version 3.6.1
has been used to perform the optimization under TOU tariff scheme.
The results have shown that the industrial load sector incur the lowest
cost of energy at the highest capital cost as opposed to the residential
and commercial load sectors. However, from economic perspective,
the residential demand sector proved to be more favorable to the
proposed hybrid system due to the lowest net present cost (NPV). For
each load demand sector, HOMER led to oversizing constraint of the
hybrid system by not recharging the storage system after use.
