Modeling and analysis of N-port DC-DC converters using the cyclic average current
TL;DR: In this paper, a new representation of the average current flowing in and out of the terminals of an N-port DC-DC converter is presented, which is called cyclic average current (CAC).

Applying a splitting technique to estimate electrical grid reliability
TL;DR: It is shown that various reliability indices can be expressed as expectations depending on the rare event probability of a so-called power curtailment, and how to extend a Crude Monte Carlo grid reliability analysis with an existing rare event splitting technique is explained.

Self-scheduling under ellipsoidal price uncertainty: conic-optimisation approach
TL;DR: In this article, a robust generator self-scheduling problem is formulated as a second-order cone program and solved using a commercially available interior-point package, and the safety parameter, which trades between profit and risk, is determined based on a prespecified chance that the realised loss would be greater than the corresponding value at risk.

Stealthy attack detection and solution strategy for consensus-based distributed economic dispatch problem
Wenming Zhang,Xing He +1 more
TL;DR: The convergence of the algorithm under a realizable and general stealthy attack is proved, and the expression of the convergence point is provided, and a strategy based on a defined observation network is proposed to detect whether the system is attacked by the false data injection to broadcast information.
