Optimal reactive power planning is one of the most challenging problems in power system operation. Different techniques including classical and modern heuristic methods have been utilized to address the problem successfully. It is observed that success of heuristic techniques largely depends on the selection of some user defined control parameters. Multiple runs are required to find the optimal values...
A new hybrid particle swarm optimization algorithm based on black-hole theory called modified black-hole particle swarm optimization (MBHPSO) is introduced in the present paper. Placement of capacitor of optimal sizes and at optimal locations not only reduces the power losses, but also improves the voltage stability of the electric power systems. Several meta-heuristic techniques have been used by...
The concept of Distributed Generation (DG) emerged in the power industry from the last few decades due to the rapid increase in electricity demand, limited conventional resources and continuous growth in nonconventional energy based low voltage and small scale power industry. In distributed generation system, the optimal placement and sizing of DG units in radial distribution network is one of the...
This paper presents a cultural algorithm based technique to achieve the optimal size and placement of Static Var Compensators (SVCs) in a power system. A multiobjective reactive power problem is chosen here to establish the feasibility of the algorithm. Two objective functions are proposed for reducing the SVC investment cost while minimizing the active power loss but maintaining voltage stability...
In general power system problems like reactive power dispatch (RPD) are nonlinear, non-differentiable and multi-constrained based. This type of problem is solved by various analytical programming and meta-heuristics algorithms. Among the different applied techniques, metaheuristics algorithms have always maintained themselves competitive with analytical programming. Simulated annealing (SA) is one...
Power loss in a distribution system is reduced indirectly by doing reactive power compensation. This is done through capacitor allocation at suitable bus locations using a metaheuristic technique named Cultural Algorithm. The objective of this approach is to maximize the profit by reducing the amount of real power loss and improving the quality of power by increasing the voltage level of each bus...
