A dynamic programming based approach was proposed to produce an optimal capacitor dispatching schedule in which the operating times of every capacitor is defined as state variables [1]. Lu and Hsu [2] applied heuristic rules to choose only limited preferable state variables for each hour to reduce the whole solution space.

Abstract: A new branch-and-bound algorithm for the placed capacitors dispatch on a distribution feeder in daily system operation is presented in this paper. An efficient branching method based on the heap data structure and a simple intuitive bounding rule based on the forecast hourly loads are proposed to reach an optimum capacitor dispatching ...
First, the optimal dispatch schedule of the capacitors is determined using a genetic algorithm (GA) with the assumption that the ULTC operates to regulate the secondary voltage. Each capacitor operates according to this dispatch schedule and the ULTC at the
This paper presents teaching learning based optimization (TLBO) approach to minimize power loss and energy cost by optimal placement of capacitors in radial distribution systems. The proposed algorithm is based on two basic concept of education namely teaching phase and learning phase.
A bank of capacitors can be charged over a period of time but discharged in a fraction of a second when required. Similarly, the rapid tranfer of energy needed for a flash bulb in a camera often involves capacitor discharge. Try dismantling a disposable camera to
When the switch closes, the inrush current flows from the source to charge the capacitance. The inrush current affects the whole system from the power source to the capacitor bank, and especially the local bus voltage which initially is depressed to zero.
The dispatch of capacitors on a distribution feeder in daily system operation is investigated. The objective is to reach an optimal capacitor dispatching schedule, based on the forecast hourly loads for the next day, such that the …
