PPT-Real-Time Transmission Congestion Management & Market E

Chad Thompson Manager Operations Support ERCOT Jeff Gilbertson Sr Market Operations Analyst ERCOT Objectives Identify what defines a constraint in the ERCOT system Identify which ERCOT application dispatches generation to resolve constraint overloads. Balanced and unbalanced transmission line Transit time effect on a transmission line at high frequencies Dominance of the reactive component over resistive component Concept of distributed elements and conditions under which the lumped element circu Advanced Computer Networks: TCP Congestion Control. 1.

Background: Congestion Control. What is congestion?. A network state where the arrival rate exceeds the service rate. Throughput starts decreasing (due to packet losses). Delay increases fast (queues build up). and. Resource Allocation. Lecture material taken from. “Computer Networks . A Systems Approach. ”, Third . Edition,Peterson. and Davie,.

ERCOT staff received questions regarding recent Reliability Unit Commitment (RUC) instructions and was asked to discuss those instructions and our general process for committing Resources using the RUC application and process.

If the transport entities on many machines send too many packets into the network too quickly, the network will become congested, with performance degraded as the packets are delayed and lost..
