Huang [15] studies the utility optimization problem in energy harvesting networks under limited average network congestion constraint and develops a close-to-optimal algorithm using the Lyapunov optimization theory, which jointly manages the power allocation and the data access control.
A congestion constraint has been considered in the model which restricts waiting time of customers to not be more than tI, and another constraint has been considered that restricts waiting time of shipments in cross docks to not be more than tI.
Actions have to be taken to handle grid congestion and constraints violation.
Structural analysis can include particularities of modern power systems such as future transmission changes, congestion, operational constraints (ramps), new entrants, new technologies, and new demand grow patterns that cannot be taken into account by simply analyzing price historical values.
In large systems, additional ways to increase system flexibility to integrate higher levels of VRE include improving joint operations of adjacent power systems as a way to share resources, additional grid infrastructure built outs to remove congestion and constraints, and market mechanisms that improve overall economics and incentivize flexibility.
"Broadband Internet access service providers should remain free to engage in pro-competitive network management techniques to alleviate congestion, ameliorate capacity constraints, and enable new services," he wrote.
The authors considered multiple attributes, such as the electricity price, transmission cost, network congestion and technology constraints.
Additional criteria can also be employed in this decision process, like buffer congestion or energy constraints, which are announced in signaling (i.e., control) messages.
To respect this issue, in this article, we introduce a multi-timescale cross-layer design along with three sets of constraints: congestion control, link delay, and power control and with the objective of maximizing the overall utility and minimizing the total link delay and power consumption.
To ensure that the express lane is available and free of congestion, protocols like Constraint-based Routing over Label Distribution Protocol (CR-LDP) and Resource Reservation Protocol-traffic engineering (RSVP-TE) can be used.
