Abstract:
In this work, the optimal power scheduling for a grid-connected hydrokinetic-battery hybrid system is
proposed to sufficiently explore hydrokinetic 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. Simulations are performed using MATLAB (R2016a),
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.
