Optimal power flow via interior-exterior method
(Ieee, 2007-01-01)
This paper presents a new approach to the resolution of the Optimal Power Flow problem. In this approach the inequality constraints are treated by the Modified Barrier and Primal-Dual Logarithmic Barrier methods. The ...
A set of linear equations to calculate the steady-state operation of an electrical distribution system
(2011-12-19)
In this paper, the calculation of the steady-state operation of a radial/meshed electrical distribution system (EDS) through solving a system of linear equations (non-iterative load flow) is presented. The constant power ...
Decentralized AC power flow for real-time multi-TSO power system operation
(2010-12-06)
This paper adjusts decentralized OPF optimization to the AC power flow problem in power systems with interconnected areas operated by diferent transmission system operators (TSO). The proposed methodology allows finding ...
A decision support system for DC optimal power flow analysis on large scale interconnected system
(2011-01-01)
This paper proposes a decision support system for the National Interconnected System in Brazil. The developed decision support system is a tool that uses a DC optimal power flow to obtain the operating status of the network ...
Pricing of reactive power support provided by distributed generators in transmission systems
(2011-10-05)
Distributed Generation, microgrid technologies, two-way communication systems, and demand response programs are issues that are being studied in recent years within the concept of smart grids. At some level of enough ...

Multiarea Optimal Power Flow using Multiobjective Evolutionary algorithm
(Ieee, 2009-01-01)
In this work the multiarea optimal power now (OPF) problem is decoupled into areas creating a set of regional OPF subproblems. The objective is to solve the optimal dispatch of active and reactive power for a determined ...
Analysis of Optimal Power Flow Formulations for HVAC and VSC-HVDC Transmission Networks
(Ieee, 2018-01-01)
The Optimal Power Flow (OPF) problem has been widely studied by researchers and electric industry practitioners for many years. Most of these studies use DC power flow equations to represent the transmission system. However, ...
Analysis of Optimal Power Flow Formulations for HVAC and VSC-HVDC Transmission Networks
(2019-01-03)
The Optimal Power Flow (OPF) problem has been widely studied by researchers and electric industry practitioners for many years. Most of these studies use DC power flow equations to represent the transmission system. However, ...
Optimal Power Flow with Voltage-Sensitive Loads in Distribution Networks
(2016-11-10)
Traditionally, the optimal power flow (OPF) assumes a constant (active and reactive) power load model and thus it neglects the effect of the voltage sensitiveness of power load injections. As a consequence, the results ...
