Swarm Intelligence for Optimal Reactive Power Dispatch
2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005This 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 ...

A novel optimization algorithm for optimal reactive power dispatch: A comparative study
2011 4th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2011Optimal reactive power dispatch (ORPD) is a key instrument to achieve secure and economic operation of power systems. Due to complex characteristics of ORPD, heuristic optimization has become an effective solver. A novel heuristic optimization algorithm namely the Mean-Variance Mapping Optimization (MVMO) is proposed to handle the ORPD problem.

Comprehensive learning particle swarm optimization for reactive power dispatch
Applied Soft Computing, 2010Reactive 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 ...

Efficient constraint handling for optimal reactive power dispatch problems
Swarm and Evolutionary Computation, 2012Abstract In power engineering, minimizing the power loss in the transmission lines and/or minimizing the voltage deviation at the load buses by controlling the reactive power is referred to as optimal reactive power dispatch (ORPD). Recently, the use of evolutionary algorithms (EAs) such as differential evolution (DE), particle swarm optimization ...

Multiagent-Based Reinforcement Learning for Optimal Reactive Power Dispatch
IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews), 2012This paper proposes a fully distributed multiagent-based reinforcement learning method for optimal reactive power dispatch. According to the method, two agents communicate with each other only if their corresponding buses are electrically coupled. The global rewards that are required for learning are obtained with a consensus-based global information ...
