MICROGRID DISPATCH, CONTROL, AND HARDWARE-IN-THE-LOOP SIMULATIONS IN A DISTRIBUTED REAL-TIME ENVIRONMENT
Abstract: Dispatch and control of microgrids
with multiple heterogeneous
dispatchable and non-dispatchable
distributed energy resources (DERs),
is one of the biggest challenges in the
future power system operation. A
microgrid can exist to serve several
different purposes with changing
priorities during the operation. As a
result, the dispatch philosophy
becomes non-trivial. A dispatch
framework is developed with flexibility
to include multiple traditional and
simultaneously, with time-varying
preferences. Multi-criteria decision
analysis (MCDA)-based approach is
adopted using discrete compromise
programming (DCP). New
performance metrics are developed
using some existing metrics for design
and real-time (RT) operation of a
microgrid. The operation is aimed at
maintaining the reliability without high
unused capacity of microgrid as
reserves. Next, a distributed
simulation environment is setup with
hardware-in-the-loop (HIL) capability.
Interfaces and delays in exchange of
simulation data can introduce errors
in the simulations. These errors are
an artifact of the distributed nature of
RT simulations and data
communication latency. Data latency
over communication networks is
stochastic. Techniques will be
developed to mitigate errors due to
variable data latency. Controls are
implemented for supporting the
operation of a microgrid in
unbalanced conditions. This will be
augmented for multiple time-scales to
enhance the inertial response of
microgrid. Interactions between
different components and the
underlying network will be considered.
