A ladder lottery, known as “Amidakuji” in Japan, is a common way to decide an assignment at random. lottery L of given permutation optimal if has the minimum number horizontal lines. In this paper, we investigate reconfiguration problem lotteries. The on set lotteries asks, two L,L? ?, find sequence ?L1,L2,…,Lk? ? such that (1) L1=L and Lk=L? (2) Li for i=2,3,…,k obtained from Li?1 by moving ba...

This paper proposes an effective technique to allocate a shunt capacitor using meta-heuristic optimization-approach for minimizing the cost of energy losses. Particle swarm optimization (PSO) algorithm incorporated with MATPOWER is trained targeted function optical placement problem. The 115-node active distribution network supplied by MESC in Mandalay area applied as scenario. results includin...

This paper presents an ant colony approach optimization to shunt capacitor placement on distribution systems under capacitor switching constraints. The optimum capacitor allocation solution is found for the system of feeders fed through their transformer and not for any individual feeder. The main advantages due to capacitor installation, such as system capacity release and reduction of overall...

This paper presents an optimization algorithm for simultaneous improvement of power quality (PQ), optimal placement and sizing of fixed capacitor banks in radial distribution networks in the presence of voltage and current harmonics. The algorithm is based on particle swarm optimization (PSO). The objective function includes the cost of power losses, energy losses and those of the capacitor ban...

This work proposes a two-stage immune algorithm that embeds the compromise programming to perform multi-objective optimal capacitor placement. A new problem formulation model that involves fuzzy sets to reflect the imprecise nature of objectives and incorporates multiple planning requirements is presented. The proposed approach finds a set of noninferior (Pareto) solutions rather than any singl...
