Optimal and resilient coordination of virtual batteries in distribution feeders
[article]
2020
arXiv
pre-print
This paper presents a novel hierarchical framework for real-time, network-admissible coordination of responsive grid resources aggregated into virtual batteries (VBs). ...
The coordination is achieved by solving an optimization problem to disaggregate a feeder's desired reference trajectory into constraint-aware set-points for the VBs. ...
A convex optimal power flow (OPF) formulation has been presented that ensures a provably tight optimal dispatch of virtual batteries (VBs) to track an economic power trajectory. ...

Optimal corrective dispatch of uncertain virtual energy storage systems
2020
IEEE Transactions on Smart Grid
The uncertainty studied herein is associated with estimating the state of charge and the capacity of an aggregation of DERs (i.e., a virtual energy storage system or VESS). ...
To optimally dispatch uncertain, energy-constrained reserves, optimization-based techniques allow one to develop an appropriate trade-off between closed-loop performance and robustness of the dispatch. ...
The approximation results in a simplified, closed-form safety-factor function with a relative error less than 15% for < 0.20 (and less than 5% for < 0.10) and is an inner approximation (i.e., more conservative ...

What mad pursuit?

Aggression and Violent Behavior
The cultural constructions of romantic and passionate love throughout the ages in poetry, song, and historical narrative suggest that obsession and mad, driven pursuit of a love object is both terrible ...
Employing a slightly more liberalized operational definition, these estimates increased to approximately 12% of women and 4% of men. ...

To optimally dispatch uncertain, energy-constrained reserves, optimization-based techniques allow one to develop an appropriate trade-off between closed-loop performance and robustness of the dispatch. ...
Therefore, a VESS's energy capacity can be approximated as an aggregation of random variables. ...

MAD trees and distance-hereditary graphs
2003
Discrete Applied Mathematics
A MAD tree of G is a spanning tree with minimum total distance. ...
We develop a linear-time algorithm to ÿnd a MAD tree of a distance-hereditary graph; that is, those graphs where distances are preserved in every connected induced subgraph. ? ...

Researching the future: method or madness?
2003
Futures : The journal of policy, planning and futures studies
methodology, the lack of clarity does not make a futures study invalid or unreliable, and hence sensemaking from the chaos of futures 'data' does ensure that futures studies can be based on method rather than madness ...
The use of stories and constructing simulations for a virtual futures experience play an important part in futures methodology. ...
The closest approximation would be an experimental design using test groups and control groups, but this could not be carried out into the future without raising serious ethical issues, and nor is it appropriate ...
