This paper provides an optimal approach to denote the location and size of ESSs (energy storage systems) with the intention of reliability improvement in radial electrical distribution networks. The proposed optimal ESSs planning is addressed as a minimization problemwhich aims at minimizing the cost of ENS (energy not supplied) as well as ESSs costs at the same time, subject to safe operation ...
This paper introduces a comprehensive process based on inspection for determination of medium voltage (MV) overhead line condition and it was tried that all factors influencing the outage distribution network integrated into one index called index. A failure rate model has been proposed its unknown parameters are calculated historical data. Shortest path problem (SPP) long term scheduling maint...
Original scientific paper Nowadays, the operational performance of the Distribution system can be improved by exchanging the functional links between the elements of the system, called reconfiguration. This paper aims at achieving such optimization through the reconfiguration of distribution systems taking into account various criteria. The newness of the method is in the fact that optimization...
Reliability is the most important factor of distribution system and this should be operated economically with low customer loads interruption. This because that gives supply to customers from transmission system. There are some power quality issues due failures components in Researchers going on assess reliability In system, evaluation an aspect complete electric planning operation. Due extreme...
A shared pool of grid-scale storage resources called Cloud Energy Storage (CES) can bring substantial benefits to the economical and reliable operation MGs. However, investment cost CES may not be affordable for a single microgrid (MG). As solution, we propose an approach in which neighboring microgrids distribution network collaborate form multi-microgrid (multi-MG) install increase their prof...
Multi-carrier energy systems (MCESs) provide collaboration between various kinds of carriers to supply the electricity, heating, and cooling demands. With widespread use MCESs in recent years, security assessment has attracted attention many contemporary researchers. However, complexity an MCES, including electrical, natural gas, district heating networks, different uncertainties imposes vast c...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
In this paper, a methodology for optimal decision making electrical systems is addressed. This seeks to identify and prioritize the replacement maintenance of power asset fleet optimizing return investment. It fulfills objective by considering risk index, costs, company revenue. The index estimated predicted each using both its condition records evaluating consequence failure. quantified as pro...
