Ali Mansouri Amin Omidian Ehsan Mohamadian Nosratollah Mohammad Beigi Rahmat Aazami,

With the development of deregulated power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benefi...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

Global warming, environmental pollution, fossil resources reduction, the increased demand and price of energy carriers, and various international social and political consequences are among the problems of traditional energy generation and distribution system. In the traditional generation systems, about two-thirds of energy is wasted and the presence of scattered energy resources such as photo...

Reaching an electricity system which is both economically efficient and environmentally friendly is motivating countries to design and execute different types of TOU demand response programs. But there are certain deficiencies which prevent these programs to effectively modify the load shape. Smart grid as a means could help the electricity system to reach the highest demand side management ...

Improper designs of the demand response programs can lead to numerous problems such as customer dissatisfaction and lower participation in these programs. In this paper, a home energy management system is designed which schedules appliances of smart homes based on the user’s specific behavior to address these issues. Two types of demand response programs are proposed for each house which are sh...

Significant decline in the slope of short-term oil supply and demand curves, along with the meaningful change in the degree of risk aversion in arbitrageurs encouraged us to test the time-varying effects of speculative demand on crude oil price dynamics over the period 1985-2016. Using a time-varying parameter vector autoregressive (TVP-VAR) model – with structural shocks identified by Killian ...

in this present study the dissolved air flotation (daf) system was investigated for the treatment of kermanshah oil refinery wastewater. the effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (cod) removal was examined experimentally. all the experiments were done under a...

In this paper, a model for hybrid transmission expansion planning (TEP) and reactive power planning (RPP) considering demand response (DR) model has been presented. In this study RPP considered by TEP for its effects on lines capacity and reduction of system expansion costs. On the other hand the expansion of the transmission system is an important subject, especially dealing with the new i...

در این پژوهش، برنامه های پاسخگویی بار (demand response) که در اکثر بازارهای برق جهان اجرا می-شوند مورد بررسی قرار می گیرند، این برنامه های نه گانه به دو گروه عمده تشویق محور و زمان محور و همچنین برنامه های تشویق محور به سه زیرگروه تشویق محور داوطلبانه (فاقد جریمه)، تشویق محور اجباری (مبتنی بر جریمه) و تشویق محور مبتنی بر تسویه بازار تقسیم شده اند. در این پژوهش، مدل غیر خطی برنامه پاسخ تقاضای ا...

In smart grids paradigm, versatile demand response programs have been devised to accommodate the load flexibilities in optimal scheduling of distribution networks and increasing the techno-economic efficiency of electrification process. The initial models for prioritizing the demand response programs are mainly valid for the case of constant and deterministic load profiles. These models are tac...
