Demand response Allows the management of customer consumption of electricity in response to supply conditions. Distributed generation Electric energy that is distributed to the grid from many decentralized locations, such as from wind farms and solar panel installations. Distribution grid The part of the grid dedicated to delivering electric energy directly to residential, commercial, and indus...
هدف از این پروژه هماهنگی عناصر حفاظت شبکه توزیع می¬باشد. از آنجاییکه شبکه توزیع مستقیما به مصرف کننده متصل می باشد، حفاظت بهینه شبکه توزیع می¬تواند درکاهش قطعی برق و افزایش قابلیت اطمینان و افزایش عمر تجهیزات نقش بسزایی داشته باشد. دریک سیستم توزیع عناصر حفاظتی شامل رله های جریان زیاد، فیوزها، کلید بازبستها، جداکننده ها و کلیدها می باشند که باید به نحو مناسب با هم هماهنگ شوند. این مسئله شامل هم...
Efficiency analysis plays an important role in price regulation in the electricity distribution sector. This paper analyses efficiency and productivity of 38 electric distribution companies in Iran from year 1387 to 1389 (Iranian calendar year) by using slack based model (SBM). Super efficiency analysis is employed to rank full efficient companies. According to results, Tabriz, Ahwaz and north ...
Power distribution system in the country is characterized by high power losses, poor reliability of supply, frequent equipment burnouts etc. The traditional approach in electric power generation is to have centralized plants distributing electricity through an extensive transmission & distribution network. Distribution generation (dg) provides electric power at a site closer to the customer, el...
Methods to solve natural gas loadflow problems using electric loadflow techniques are presented. The motivation is to integrate a natural gas network with an electric power transmission network so that the network analysis for a combined natural gas and electric power distribution network can be performed in a consistent manner. The issues arising from solving gas loadflow problems are discusse...
transmission network expansion planning (tnep) is an important component of power system planning. itdetermines the characteristics and performance of the future electric power network and influences the powersystem operation directly. different methods have been proposed for the solution of the static transmissionnetwork expansion planning (stnep) problem till now. but in all of them, stnep pr...

Increased electric energy consumption in recent years, associated economic problems, reduced reliability and increased power losses in electric networks. One of the main solutions in smart grids to overcome the mentioned problems is demand response programs. In demand response programs, operators apply time-varying tariffs to consumers, and convince them to change their consumption pattern. Amo...
The proliferation of distributed energy resources (DERs) in electric distribution networks brings both challenges and opportunities to the management of the electric grid. In the right locations these resources can provide value to the network by reducing congestion and losses and deferring investment in network upgrades. To unlock this value, however, more efficient economic signals need to be...
