In a deregulated electricity market one of the most important tasks of independent system operator (ISO) is to manage congestion as it threatens system security and may cause rise in electricity price resulting in market inefficiency. In corrective action of congestion management schemes, it is crucial for ISO to select the most sensitive generators to re-schedule their real and reactive powers optimally...
In a deregulated electricity market transmission congestion occurs when there is insufficient transmission capacity to simultaneously accommodate all requests for transmission service within a region. One of the most important tasks of independent system operator (ISO) is to manage congestion as it threatens system security and may cause rise in electricity price resulting in market inefficiency....
Capacity market provides additional revenue stream for the power suppliers. In a capacity-energy combined market environment, suppliers have incentives to deliberately over-offer their capacities in the capacity market while bid very high price in the energy and ancillary markets to avoid operation. This paper analyzes the risks and profits of this capacity-over-offer behavior, and develops a method...
Deregulation in electricity industry necessitates wide access to transmission networks that connect consumers and suppliers. As congestion in the transmission networks is a key obstacle to vibrant competitive electricity markets Thus; one of the most challenging problems for a deregulated power environment is how to handle the transmission congestion. The main objective of the transmission congestion...
Although real power is the main traded commodity in electricity markets, reactive power plays crucial roles in power systems reliability and security. Market participants utilize the network differently to maximize their profits. It means that their effects on the system, such as losses, can also be different. The development of a fair and accurate loss allocation scheme for real and reactive power...
