Abstract

The widespread penetration of distributed energy sources and the
use of load response programs, especially in a microgrid, have caused many
power system issues, such as control and operation of these networks, to
be affected. The control and operation of many small-distributed generation
units with different performance characteristics create another challenge for
the safe and efficient operation of the microgrid. In this paper, the optimum
operation of distributed generation resources and heat and power storage in
a microgrid, was performed based on real-time pricing through the proposed
gray wolf optimization (GWO) algorithm to reduce the energy supply cost
with the microgrid. Distributed generation resources such as solar panels,
diesel generators with battery storage, and boiler thermal resources with
thermal storage were used in the studied microgrid. Also, a combined heat
and power (CHP) unit was used to produce thermal and electrical energy
simultaneously. In the simulations, in addition to the gray wolf algorithm,
some optimization algorithms have also been used. Then the results of 20
runs for each algorithm confirmed the high accuracy of the proposed GWO
algorithm. The results of the simulations indicated that the CHP energy
resources must be managed to have a minimum cost of energy supply in the
microgrid, considering the demand response program.
