In countries with Capacity Mechanisms in place, where Explicit Interconnector Participation model is to be used, one of the key market design questions to be answered is how the amount of interconnector capacity that is allowed to participate in the auctions should be determined. This paper argues for an interconnector capacity de-rating approach. In order for the de-rating factor to be representative...
One of the most pressing concerns in the investigation of new probabilistic reliability criteria pertains to the data required as input to the evolving probabilistic models. This paper discusses an area of failure data collection that has been overlooked in power system reliability studies: corrective control actions. Background information is provided on the need for evolution of data collection...
The purpose of this paper is to present a review of some fundamental concepts and practical applications in the area of common-mode and dependent (CMD) outage events in power systems. The paper is a result of ongoing activity carried out by the Probability Applications for Common and dependent Mode Events (PACME) Working Group (WG) of the Reliability, Risk and Probability Applications Subcommittee...
Relatively fewer studies exist in literature on including the complex effects of transmission protection system related failure dependencies in the reliability prediction models. Usage of extensive Markov models has been usually advocated to capture the impact of protection system reliability on power system reliability. A new analytical method which makes use of approximate methods of system reliability...
In order to capture the effect of dependent failures that could arise due to the various transmission protection system response scenarios on power system reliability, complex Markov models or fault trees combined with event trees are typically employed in the predictive reliability studies. A unique approach utilizing minimal cutsets (MC) and the approximate methods of system reliability evaluation,...
Several studies on the migration strategies to enable the realization of various visions of Smart Grids (SGs) from the existing legacy power systems are on the anvil. A subjective treatment of ‘reliability’ as encountered in the several existing working definitions on SGs leaves much to be desired. Only a quantification of envisioned reliability benefits and impacts can justify the rationale for embracing...
