Multiarea optimal power flow using multiobjective evolutionary algorithm
(2009-12-17)
In this work the multiarea optimal power flow (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 ...
Modified barrier method for optimal power flow problem
(2004-12-01)
In this paper is presented a new approach for optimal power flow problem. This approach is based on the modified barrier function and the primal-dual logarithmic barrier method. A Lagrangian function is associated with the ...

Optimal Power Flow with Voltage-Sensitive Loads in Distribution Networks
(Ieee, 2016-01-01)
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 ...
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, ...

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 ...
