Abstract:
This paper proposes an optimal energy management
model for a grid-connected micro-hydrokinetic pumped hydro
storage (MHK-PHS) hybrid system supplying the commercial load.
The aim of the model is to minimize the energy costs through
power-flow control variables and time-of-use (TOU) tariff scheme.
The optimization problem will be solved through the use of the
linprog solver in the MATLAB’s optimization toolbox for 216 hours
as a means of including the weekend as well. The simulation results
show that the developed model can assist the onsite MHK-PHS
hybrid system to optimally reduce the electricity consumption cost
of the commercial load. Additionally, Sundays have proved to lead
to concurrent use of all power sources for the entire business hours
of the commercial load.
