Contingency-Constrained Optimal Power Flow Using Simplex-Based Chaotic-PSO Algorithm

open access: yesApplied Computational Intelligence and Soft Computing, 2011
This paper proposes solving contingency-constrained optimal power flow (CC-OPF) by a simplex-based chaotic particle swarm optimization (SCPSO). The associated objective of CC-OPF with the considered valve-point loading effects of generators is to ...

On Variable Reverse Power Flow-Part I: Active-Reactive Optimal Power Flow with Reactive Power of Wind Stations

open access: yesEnergies, 2016
It has recently been shown that using battery storage systems (BSSs) to provide reactive power provision in a medium-voltage (MV) active distribution network (ADN) with embedded wind stations (WSs) can lead to a huge amount of reverse power to an ...

Distributed Optimal Power Flow for Large-Scale Multi-Area Interconnected Power Systems

open access: yesCSEE Journal of Power and Energy Systems
Distributed optimal power flow (OPF) of large-scale multi-area interconnected power systems is a challenging problem. This letter proposes a distributed OPF approach based on the modified decomposition-coordination interior point method (DCIPM).

Optimization of Optimal Power Flow Problems [PDF]

open access: yesPAMM, 2011
AbstractOptimal power flow problems arise in the context of the optimization and secure exploitation of electrical power in alternating current (AC) networks. This optimization problem evaluates the flow on each line and to ensure that they are under line thermal limits. To improve the reliability of the power supply, a secure network is necessary, i.e.

Optimal power flows

open access: yesInternational Journal of Electrical Power & Energy Systems, 1979
Abstract The state of the art of optimal flows at the end of 1978 is reviewed. The different aspects of the problem statement are established in the most complete way possible; then methods for the solution of the static optimization are presented and filed, with a brief description of the most typical ones, trying to show the respective merits of ...

Operating Power Grids with Few Flow Control Buses

open access: yes, 2015
Future power grids will offer enhanced controllability due to the increased availability of power flow control units (FACTS). As the installation of control units in the grid is an expensive investment, we are interested in using few controllers to ...

Strong SOCP Relaxations for the Optimal Power Flow Problem

open access: yes, 2015
This paper proposes three strong second order cone programming (SOCP) relaxations for the AC optimal power flow (OPF) problem. These three relaxations are incomparable to each other and two of them are incomparable to the standard SDP relaxation of OPF ...
