Optimal reactive power dispatch considering wind turbines

2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014
This paper succeeds in solving the optimal reactive power dispatch (ORPD) of power system where the units contains wind turbines. Two types of wind turbine are taken into account in the ORPD, and they are the variable speed wind turbine (VSWT) and the fixed speed wind turbine (FSWT). Besides, the primal dual interior point method is introduced to serve

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.

Genetic algorithm for optimal reactive power dispatch

Proceedings of EMPD '98. 1998 International Conference on Energy Management and Power Delivery (Cat. No.98EX137), 2002
Scheduling of reactive power in an optimum manner reduces circulating VAr promoting flatter voltage profile which lead to appreciable MW saving on account of reduced power system losses. Hence, the optimal reactive power dispatch assumes extremely important functioning both in the planning stage as well as in day to day operation of the power system ...

Optimal reactive power dispatch using JAYA algorithm

2018 Emerging Trends in Electronic Devices and Computational Techniques (EDCT), 2018
Optimal reactive Power Dispatch (ORPD) is a very useful mechanism for achieving an economic and secure operation of the power system. The problem is formulated as a single objective, complex non-linear, optimization problem containing different control variables to determine the optimal solution while satisfying various constraints simultaneously.

Swarm Intelligence for Optimal Reactive Power Dispatch

2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005
This paper presents swarm intelligence to solve optimal reactive power dispatch (ORPD) problem. Results derived with swarm intelligence, improved genetic algorithm and a conventional gradient-based optimization method were compared. The comparison shows that swarm intelligence would produce similar results on the IEEE 30-bus system as those from ...

Optimal reactive power dispatch control considering uncertain wind power

2017 International Conference on Robotics and Automation Sciences (ICRAS), 2017
In this paper, a downside risk constrained optimal reactive power dispatch control (ORPDC) model is proposed, with the consideration of uncertain wind power integrated into power systems. In this model, the expectation of transmission loss and its downside risk are considered, simultaneously.

Power system optimal reactive power dispatch using evolutionary programming

IEEE Transactions on Power Systems, 1995
This paper is concerned with application of evolutionary programming (EP) to optimal reactive power dispatch and voltage control of power systems. Practical implementation of the EP for global optimization problems of large-scale power systems has been considered. The proposed EP method has been evaluated on the IEEE 30-bus system.
