In order to sustain a continuous supply of electric power during a potential N-1 event, sufficient amount of reserves have to be acquired. The acquisition of such contingency reserves starts at the day-ahead scheduling phase. However, modern day-ahead unit commitment problems, which acquire reserves that exceed the largest contingency, do not guarantee a reliable solution as the deliverability of...
To regard environmental protection renewable energy sources especially wind, has been applied to achieve emission reduction goals. While wind generation does not directly produce air pollutants emission, it causes some changes on thermal power generation scheduling which may lead them to produce more air pollutants emission especially during low and medium energy demand periods. So it seems necessary...
Textile effluents are major industrial polluters. The present paper aims to investigate and develop low cost adsorption methods for color removal wastewater using waste materials raw (RP) and activated carbon (ACP) from plane tree yellow leaves as adsorbent. The method was applied for the removal of direct red 81 while the influence of various factors such as adsorbate concentration and pH were studied...
The walnut shell, an agricultural waste, has been activated and used as an adsorbent for the adsorption of Direct and Reactive dyes from aqueous solution. Using a batch adsorption technique with respect to initial concentration and temperature the effects of various experimental parameters have been investigated. Equilibrium isotherms were analyzed by Langmuir, Freundlich, Temkin and Dubinin-Radushkevich...
