“…A formula to estimate the loss change resulting from the transfer of a group of loads from one feeder to another feeder by the closing of single tie switching and the opening of a single sectionalizing switch [7]. A method is described for reconfiguration with the potentials for handling realistic operating constraints [8]. The approach taken is to set up a decision tree to represent the various switching operations available.…”

This paper presents hierarchical compensation technique for loss minimization in distribution system by optimum location of capacitor. The electric distribution system serves an important role in achieving satisfactory power supply. The power quality is measured by good voltage profile and voltage stability. In addition the distribution system should be operated under optimum loss condition. In view of recent power sector reforms lot of emphasis has been given to these aspects. In order to get optimized operating condition the reactive compensation methodology is adapted. The proposed approach identifies the proper location & size of compensation depending on the main feeder, laterals, and sub laterals owing to their hierarchy. The cost analysis gives the amount of saving achieved per annum. The approach is tested on 15 bus test distribution system. The technique serves as a useful tool for optimized distribution system operation.

“…2, switch is fired to open to release the loading of z1 when all of the states of three input place nodes of the transition node are met: s(C) implies switch is closed; z2(E&NT) implies z2 is an energized, nonterminal zone; z1(E&T) implies that the objective zone z1 is energized and terminal. The fired transition node will open switch to generate three new output place nodes: s(O) is with switch is opened; z1(DE&NT) implies z1 is a de-energized and nonterminal zone, while z2(E&T) implies that z2 is an energized and terminal zone according to the "if then " rule as expressed in the notation in (10). Similarly, in (11) is to release the loading of z2 by opening switch .…”

Abstract-This study attempts to determine the daily load patterns of service zones, line switches, distribution feeders, and main transformers by using customer information in a customer information system (CIS) and information about distribution transformers in the outage management information system (OMIS) in Taiwan Power Company (Taipower). When a power distribution system is operating under normal conditions, the reconfiguration of feeders for balancing loads among distribution feeders is obtained by the colored Petri nets (CPN) inference mechanism, which improves the operating performance of distribution systems. A practical Taiwan power distribution system, with daily load patterns derived by a load survey, is used for a computer simulation and, thus, determines the effectiveness of the proposed methodology to improve the balancing of the feeder load for distribution systems by considering the load characteristics of the service customers.Index Terms-Colored Petri nets, feeder reconfiguration, load balancing, load patterns, switching operations.

“…Tim Taylor used heuristic best-first search strategy as far as possible to eliminate the combination of the switch states of violating the constraint condition, in order to reduce the state space, which is asked for searching [1] . S. Civanlar deduced a formula of the change of network losing when a group of load transfers from one feeder to another, and pointed out that only when load transfers from one point of low electromotive force to another of high electromotive force and the potential difference between these two points is large enough, it is probable to cause the decrease of network losing [2] .…”

Abstract-This paper proposes a kind of encoding method with the loop switch number as gene and the number of branches of the systematic loop as the length of the chromosome, greatly shortening the length of the chromosome. And this paper also takes a kind of effective means in genetic operation, which is eliminating island and loop circuit, thus greatly decreasing the generation of infeasible solution in the operation to gene and increasing the searching ability and speed of the algorithm. The result indicates that, the combination of adaptive control and genetic algorithm, the adaptive adjusting to the crossover rate and mutational rate accelerate the searching speed of the algorithm, and effectively avoid immature convergence.
