Abstract:
Due to technological developments, some isolated
areas, where consumers were supplied with electricity using
standalone hybrid systems, are currently being connected to the
grid. The new problem induced by these advancements is to find
how to efficiently operate these grid-connected systems.
The present paper proposes a multi-objective energy management
model in order to optimize the short-term operation of a gridconnected
hybrid system supplying an industrial load while
participating to the Time of Use Demand Side Management
program.
The main purpose of the developed model is to minimize the
operation cost of a proposed grid-connected hybrid energy system
consisting of a photovoltaic unit, a wind unit and a battery storage
system while optimizing the system’s power flow considering the
different component’s operational constraints. The simulations
have been performed using “linear programming” implemented
in Matlab. The simulation results demonstrate that the developed
model can assist the hybrid system in reducing the operation cost
and allow consumers to generate substantial income by selling
power to the grid.
