Due to the deregulation trend in electric power system networks, many factors have to be taken into consideration such as lack of supplying electric power, system reliability, power quality, electric system losses and voltage disturbance and profile problems. The excessive growing needs for electricity force electrical researchers to implement new approaches through the electric system. Introdu...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...

Network reconfiguration (NR) is a powerful approach for power loss reduction in the distribution system. This paper presents method of network using adaptive sunflower optimization (ASFO) to minimize ASFO developed based on original (SFO) that inspired from moving sun. In ASFO, mechanisms including pollination, survival and mortality have been adjusted compared SFO fit with problem. The numeric...

In this paper, static and expansion planning of electric power distribution networks were studied using a novel Particle Swarm Optimization (PSO) algorithm under load uncertainty is presented. This paper consists of two sections. At first by using a novel PSO algorithm, static and mono objective planning was solved for electric distribution network. This work involves both network topology and ...

Power quality is becoming a more concern of today’s power system engineer due to rapid growth of non-linear loads in distribution network. Electrical Arc Furnace (EAF) is one of the responsible causes for deteriorating power quality in the distribution network. Hence electric arc furnace model is needed to study and to analyze the power quality in the distribution network. This paper presents a...
