Chance-Constrained Optimal Power Flow: Risk-Aware Network Control under Uncertainty
- D. Bienstock, M. Chertkov, S. Harnett

- 25 September 2012
Smart grid goals include a commitment to large penetration of highly fluctuating renewables, thus calling to reconsider current practices, in particular the use of standard OPF, which can lead to frequent conditions where power line flow ratings are significantly exceeded.

It is found that local control schemes are able to maintain voltage within acceptable bounds and how the control system can be continuously tuned between robust voltage control, suitable for daytime operation when circuit conditions can change rapidly, and loss minimization better suited for nighttime operation.

The New England power grid model is used to demonstrate that the proposed combination of the sparsity-promoting control design with the slow coherency objectives performs almost as well as the optimal centralized control while only making use of a single wide-area communication link.

The derivation details, logic, and motivation for the three loop calculus introduced in Chertkov and Chernyak (2006 Phys.
Phenomenology of Rayleigh-Taylor turbulence.
- M. Chertkov
- PhysicsPhysical Review Letters
- 9 September 2003
This work analyzes the advanced mixing regime of the Rayleigh-Taylor incompressible turbulence in the small Atwood number Boussinesq approximation to resolve the temporal behavior and the small-scale spatial correlations of velocity and temperature fields inside the mixing zone.
Local Control of Reactive Power by Distributed Photovoltaic Generators

- 1 June 2010
A local control scheme that dispatches reactive power from each PV inverter based on local instantaneous measurements of the real and reactive components of the consumed power and the real power generated by the PVs is suggested.
Small-Scale Turbulent Dynamo

Kinematic dynamo theory is presented here for turbulent conductive fluids. We describe how inhomogeneous magnetic fluctuations are generated below the viscous scale of turbulence where the spatial…
Lagrangian tetrad dynamics and the phenomenology of turbulence
- M. Chertkov, A. Pumir, B. Shraiman
- Physics
- 18 May 1999
A new phenomenological model of turbulent fluctuations is constructed by considering the Lagrangian dynamics of four points (the tetrad). The closure of the equations of motion is achieved by…
