امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
Economical harvesting of electrical energy on a large scale considering the environmental issues is a challenge. As a solution, Microgrids (MGs) promise to facilitate the widely penetration of renewable energy sources (RESs) and energy storage devices into the power systems, reduce system losses and greenhouse gas emissions, and increase the reliability of the electricity supply to the customer...
The development of renewable-energy-based microgrids is being considered as a potential solution to lessen the unrelenting burden on centralized utility grid. Furthermore, recent studies reveal that integrated multi-microgrid cluster systems developed in urban communities maximize effectiveness and greatly decrease grid dependence. However, due uncertain nature renewable energy sources frequent...
Microgrids are able to dispatch power distribution systems with the advancement of electronics-based inverters. As per IEEE-1547-2018 standards, Microgrid has maintain voltage 0.88 < V 1.1 p.u (per unit) and frequency 58.8< f_0 61.2 Hz detect un-intentional faults in less than 2 seconds bring into islanding mode seamlessly. Unless these detected is islanded, system stability cannot be maintaine...
this paper develops a model for distribution network expansion planning (dnep) considering reliability issues. with simultaneous switch placement and dnep, the proposed model tries to adequately consider the reliability issues in the planning stage in a way that the designed network has suitable performance from the reliability viewpoint. the reinforcement or installation of mv feeders and hv/m...
