Abstract:
In this work, the optimal power scheduling
for a grid-connected hydrokinetic-battery hybrid system is
proposed to sufficiently explore hidrokinetic energy and
to benefit customers at demand side. The developed
model for the hybrid system’s optimal power flow
management aims to minimize electricity cost subject to
the power balance, hydrokinetic and battery storage
outputs as well as other operational constraints. With
respect to demand side management, an optimal control
method is developed to schedule the power flow of hybrid
system over 24-h. Simulation are performed using
MATLAB, and the results demonstrate that operating the
proposed hybrid system under the developed optimal
energy management model can reduce the operation cost
and allow consumers to generate substantial income by
selling power to the grid.
