ACOPF with SOCP Hierarchy for Power Loss Minimization

2021 18th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2021
Power loss minimization can decrease the dispatch cost of operation and improve system security. Thus, power loss minimization plays an important role in a power distribution system. In this paper, the alternating current optimal power flow (ACOPF) problem is proposed to optimize the transmission loss taking into account system operating limits.

Minimization of Power Losses in Cooperating Manipulators

1991 American Control Conference, 1991
The control of multiple manipulators handling a common object entails the solution of an underdetermined system of linear equations which represents the system’s dynamics. In order to choose an optimal solution to this problem, various approaches have been proposed: minimum internal force and minimum power, among others.

Loss Minimizing Control of PMSM for Electric Power Steering

2015 17th UKSim-AMSS International Conference on Modelling and Simulation (UKSim), 2015
Electric drives are very useful in propelling the wheels of hybrid and electric vehicles (HEVs). They also play a central function in the electric power steering (EPS). In this paper, a loss minimizing scheme for permanent magnet synchronous motor (PMSM) was derived analytically and takes into consideration copper, iron and stray losses.

Loss Power Minimization Using Particle Swarm Optimization

The 2006 IEEE International Joint Conference on Neural Network Proceedings, 2006
This paper presents a particle swarm optimization (PSO) as an efficient approach for loss reduction study. This issue can be formulated as a nonlinear optimization problem. The proposed approach employs the PSO algorithm for optimal setting of optimal power flow (OPF) based on loss minimization (LM) function.

Minimization of water losses for optimal hydroelectric power generation

21st Mediterranean Conference on Control and Automation, 2013
This paper deals with the problem of reducing water losses during power generation in hydro-power valleys. Because the main resources is water, it is important to guarantee that the demanded power per hour is generated in such a way that water is used as much as possible along the valleys. That is achieved by minimizing the spilling flows.

Reactive Power Planning for transmission loss minimization

2011 5th International Power Engineering and Optimization Conference, 2011
Total system losses of the power system relate to the reactive power management in the network. This paper presents a method to minimize the system losses by utilizing Reactive Power Planning (RPP) approach. In this technique, the control variables of RPP were formulated as an optimization problem and Multiagent Immune Evolutionary Programming (MAIEP ...

Induction motor drives with minimal power losses

Russian Electrical Engineering, 2012
The goal is to synthesize a control system for an induction motor such as to ensure operation with minimal power losses. Standard nonlinearity and losses in the steel of the motor’s stator are taken into account in MatLab simulation. The proposed control system reduces the losses by up to 25% in comparison with classical scalar control.
