Decentralized AC power flow for real-time multi-TSO power system operation
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 set of linear equations to calculate the steady-state operation of an electrical distribution system
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 ...
Pricing of reactive power support provided by distributed generators in transmission systems
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 ...
A geometric interpretation for transmission real losses minimization through the optimal power flow and its influence on voltage collapse
(Elsevier B.V., 2002-06-28)
This work presents an approach for geometric solution of an optimal power flow (OPF) problem for a two bus system (a slack and a PV busses). Additionally, the geometric relationship between the losses minimization and the ...
Placement and sizing evaluation of distributed generation in electric power systems
This paper presents a methodology for the placement and sizing evaluation of distributed generation (DG) in electric power systems. The candidate locations for DG placement are identified on the bases of Locational Marginal ...
A modified Primal-Dual Logarithmic-Barrier Method for solving the Optimal Power Flow problem with discrete and continuous control variables
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The aim of solving the Optimal Power Flow problem is to determine the optimal state of an electric power transmission system, that is, the voltage magnitude and phase angles and the tap ratios of the transformers that ...
