Abstract
The large integration of renewable energy into the
power grid requires frequency regulation and
ancillary services support. Grid-connected
microgrids, which naturally include a portfolio of
distributed energy resources and flexible loads, are
a promising tool that can provide this utility by
adapting their tie-line power to track frequency
regulation signals. In this paper, we propose a
framework by which grid-connected microgrids can
participate in a frequency-regulation market and
respond to a frequency-regulation request by
leveraging their distributed energy resources and
loads. The proposed framework is hierarchical, with
a central and lower layers focusing on a
microgrid. The central layer solves an energy
dispatch problem that aims to match the tie-line
power to the automatic generation control (AGC)
signal. The lower layer post-adjusts the optimum of
the central layer through distributed optimization
with consideration of the power flow constraints and
uncertain loads in the microgrid. The framework
combines recent progress on distributed algorithms,
optimal power flow solvers, and regulation market in
a novel way. Simulations demonstrate the
effectiveness of the proposed framework.
