• A novel chance-constrained OPF model that accounts for contextual information The dependence between the wind power forecast and its error is exploited robust to ambiguity in conditional distribution Compared others, our method produces reliable solutions are cheaper In this paper, we develop a distributionally formulation of Optimal Power Flow problem (OPF) whereby system operator can levera...

The existence of locally optimal solutions to optimal power flow (OPF) problems has been a question of interest for decades. This paper presents examples of local optima on very simple power system networks. Usually local optima occur when the network is stressed, and the resulting voltage profiles are infeasible in practice; however, we present examples where the voltage is within practical li...

This study reviews the form of the ISO’s DC Optimal Power Flow (OPF) problem in the AMES wholesale power market testbed.

The purpose of this paper is to present a literature review of the AC Optimal Power Flow (ACOPF) problem and propose areas where the ACOPF could be improved. The ACOPF is at the heart of Independent System Operator (ISO) power markets, and is solved in some form every year for system planning, every day for day‐ahead markets, every hour, and even every 5 minutes. It was first formulated in 1962...

Power Control Centers need to model their systems in real-time to support the necessary control and security functions. Neighboring independent system operators and regional transmission organizations also need to exchange system data. In the USA, a data exchange structure based on EPRI’s common information model and XML is evolving. Currently, this data exchange is implemented by providing eac...

The optimal power flow (OPF) problem seeks to control the generation/consumption of generators/loads to optimize certain objectives such as to minimize the generation cost or power loss in the network. It is becoming increasingly important for distribution networks due to the emerging distributed generation and controllable loads. In this paper, we study the OPF problem in distribution networks...
