Title: A Multiobjective Approach to Multimicrogrid System Design,
Abstract: The main goal of this paper is to design a market operator (MO) and a
distribution network operator (DNO) for a network of microgrids in
consideration of multiple objectives. This is a high-level design and only
those microgrids with nondispatchable renewable energy sources are considered.
For a power grid in the network, the net value derived from providing power to
the network must be maximized. For a microgrid, it is desirable to maximize the
net gain derived from consuming the received power. Finally, for an independent
system operator, stored energy levels at microgrids must be maintained as close
as possible to storage capacity to secure network emergency operation. To
achieve these objectives, a multiobjective approach is proposed. The price
signal generated by the MO and power distributed by the DNO are assigned based
on a Pareto optimal solution of a multiobjective optimization problem. By using
the proposed approach, a fair scheme that does not advantage one particular
objective can be attained. Simulations are provided to validate the proposed
methodology.
