Distribution system planning is extremely important for the end consumers of electricity; it is indeed become necessity to explore the area of real term planning of distribution system. The practical planning of distribution system incorporates the selection of optimal conductor size selection and capacitor placement in radial distribution network in distribution system. The load flow needs to ...

High-impact, low-probability events that cause significant annual damages seriously threaten the health of distribution networks. The effects these have made expansion planning for systems something beyond traditional reliability criteria, so there is an ever-increasing need modifications in current approaches and focusing on resilience new attitude dealing with distributed generation sources n...

Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

in recent years, in iran and other countries the power systems are going to move toward creating a competition structure for selling and buying electrical energy. these changes and the numerous advantages of dgs have made more incentives to use these kinds of generators than before. therefore, it is necessary to study all aspects of dgs, such as size selection and optimal placement and impact o...

This study presents a dynamic way in a DG planning problem instead of the last static or pseudo-dynamic planning point of views. A new way in modeling the DG units’ output power and the load uncertainties based on the probability rules is proposed in this paper. A sensitivity analysis on the stochastic nature of the electricity price and global fuel price is carried out through a proposed model...

Abstract Reliability and active power loss are two fundamental parameters in the design and planning of distribution systems that have always attracted the attention of power distribution systems designers and engineers. The improvement of reliability and the reduction of power loss are investigated as the primary objective functions and voltage profile as the secondary objective function. A me...

This paper presents a fuzzy system for reliability-based power distribution network planning. The proposed Mamdani type inference with subsequent application of the Bellman-Zadeh decision-making method is used to evaluate reliability line feeders as criteria Unplanned outages components, Energy Not Supplied (ENS) and age lines are input variables fuzzified using triangular functions. model was ...
