This paper reports concerns of capacitor placement in power distribution systems in the locality of a dynamic voltage restorer (DVR). A feedback controlled simulation model of an actual DVR is developed to perform case studies. Cogency of this model is established by associat ing the waveforms from the model with field measurements. Issues relating to expansion of a DVR in the locality of power...

This paper introduces a new stochastic optimization framework based bat algorithm (BA) to solve the optimal distribution feeder reconfiguration (DFR) as well as the shunt capacitor placement and sizing in the distribution systems. The objective functions to be investigated are minimization of the active power losses and minimization of the total network costs an. In order to consider the uncert...

In the present day power systems, Distributed generation (DG) technologies are becoming more significant due to the increased demand for electrical power. Integration of DG affects the performance of distribution network significantly. DG placement key benefits are power loss reduction and improved voltage profiles which are the objectives in this problem. This paper presents a new efficient te...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
