Comprehensive learning particle swarm optimization for reactive power dispatch

Applied Soft Computing Journal, 2010
Reactive power dispatch (RPD) is an optimization problem that reduces grid congestion by minimizing the active power losses for a fixed economic power dispatch. RPD reduces power system losses by adjusting the reactive power control variables such as generator voltages, transformer tap-settings and other sources of reactive power such as capacitor ...

Optimal Reactive Power Dispatch Using SunFlower Algorithm

2021 International Conference on System Science and Engineering (ICSSE), 2021
Optimal reactive power dispatch (ORPD) is one of the complicated problems in the power system operation since it optimizes a chosen objective while all power system constraints must be satisfied. Recently, many algorithms have been developed to solve the ORPD problem. This paper is applied a Sun Flower optimization (SFO) algorithm to solve ORPD problem

A Reactive Power Model for a Simultaneous Real and Reactive Power Dispatch

2007 IEEE Power Engineering Society General Meeting, 2007
This paper investigates the simultaneous dispatch of real power and reactive power in restructured electricity markets. In this proposed method the opportunity cost of supplying reactive power is implicitly modeled using the rating of the machine as a constraint.

Collaborative optimization of economic dispatch and reactive power dispatch

2019 Chinese Control Conference (CCC), 2019
Economic dispatch and reactive power dispatch are two important tasks in power systems, which respectively concern the economy and environmental friendliness and the safety and reliability of grid operation. Essentially different from the related literature with separately solving the two dispatches, this paper is devoted to collaboratively optimizing ...

Reactive-power dispatch by successive quadratic programming

IEEE Transactions on Energy Conversion, 1989
The reactive-power dispatch is formulated as the minimization of real-power losses in the system, utilizing a full set of control variables: generator voltages, switchable shunt susceptances, and transformer taps. The solution of the loss problem is obtained by successively solving quadratic programming problems.

Optimal reactive power dispatch with fuzzy variables

1993 IEEE International Symposium on Circuits and Systems, 2002
The authors present a consistent treatment of the optimal reactive power dispatch problem taking into account the uncertainty associated with load values. Linguistic declarations of loads are translated into possibility distribution functions via fuzzy sets.

Security-constrained reactive power dispatch

IEEE Transactions on Power Systems, 1991
A method of solving the preventive security-constrained reactive power VAr dispatch problem is presented. A decomposition-coordination scheme is conceived in order to take advantage of the special structure of the problem. Instead of tearing the network, the problem itself is decomposed into smaller subproblems. Techniques are presented for contingency

Sparse Linear Reactive Power Dispatch

IFAC Proceedings Volumes, 1985
Abstract This paper presents a Linear Programming (LP) based algorithm to solve reactive power dispatch problems. Linear sensitivities are derived using the reactive power model from the fast decoupled power flow solution method. A suitable criterion is suggested to form a sparse reactive power sensitivity matrix.

Optimal real and reactive power dispatch

Electric Power Systems Research, 1984
Abstract This paper presents a method for optimal real and reactive power dispatch for the economic operation of power systems. As in other methods, the problem is decomposed into a P-optimization module and a Q-optimization module, but in this method both modules use the same generation cost objective function.
