Abstract
Smart grid constrained optimal control is a
complex issue due to the constant growth of grid complexity
and the large volume of data available as input to
smart device control. In this context, traditional centralized
control paradigms may suffer in terms of the timeliness of
optimization results due to the volume of data to be processed
and the delayed asynchronous nature of the data
transmission. To address these limits of centralized control,
this paper presents a coordinated, distributed algorithm
based on distributed, local controllers and a central coordinator
for exchanging summarized global state information.
The proposed model for exchanging global state
information is resistant to fluctuations caused by the
inherent interdependence between local controllers, and is
robust to delays in information exchange. In addition, the
algorithm features iterative refinement of local state estimations
that is able to improve local controller ability to
operate within network constraints. Application of the
proposed coordinated, distributed algorithm through
simulation shows its effectiveness in optimizing a global
goal within a complex distribution system operating under
constraints, while ensuring network operation stability
under varying levels of information exchange delay, and
with a range of network sizes.
