A new solution to the optimal power flow problem
(2001-12-01)
A new approach to solving the Optimal Power Flow problem is described, making use of some recent findings, especially in the area of primal-dual methods for complex programming. In this approach, equality constraints are ...
Optimal Reactive Power Planning Using Two-Stage Stochastic Chance-Constrained Programming
(Ieee, 2013-01-01)
In this paper, the optimal reactive power planning considering uncertainty is presented. The classical deterministic mixed-integer nonlinear model is expanded into two-stage stochastic model with chance-constraint. This ...

Optimal contract pricing of distributed generation under a competitive framework
(2010-07-26)
A bilevel programming approach for the optimal contract pricing of distributed generation (DG) in distribution networks is presented. The outer optimization problem corresponds to the owner of the DG who must decide the ...
A nonlinear model for the long-term hydro-thermal generation scheduling problem over multiple areas with transmission constraints
(2009-09-22)
This paper presents a nonlinear model with individual representation of plants for the centralized long-term hydrothermal scheduling problem over multiple areas. In addition to common aspects of long-term scheduling, this ...
Market-driven security-constrained transmission network expansion planning
(2011-05-31)
This paper presents a Bi-level Programming (BP) approach to solve the Transmission Network Expansion Planning (TNEP) problem. The proposed model is envisaged under a market environment and considers security constraints. ...
Transmission network expansion planning in full open market considering security constraints
(2005-12-01)
This paper presents a mathematical model and a methodology to solve the transmission network expansion planning problem with security constraints in full competitive market, assuming that all generation programming plans ...
Optimal reactive power dispatch using stochastic chance-constrained programming
(2012-11-27)
Deterministic Optimal Reactive Power Dispatch problem has been extensively studied, such that the demand power and the availability of shunt reactive power compensators are known and fixed. Give this background, a two-stage ...
Analysis of numeric conditioning of Hessian matrix of Lagrangian via singular values
(2007-12-01)
This paper presents an analyze of numeric conditioning of the Hessian matrix of Lagrangian of modified barrier function Lagrangian method (MBFL) and primal-dual logarithmic barrier method (PDLB), which are obtained in the ...
Optimal switch allocation for automatic load transfer in distribution substations
(2011-10-05)
This work proposes a methodology for optimized allocation of switches for automatic load transfer in distribution systems in order to improve the reliability indexes by restoring such systems which present voltage classes ...
