Abstract: In traditional generation systems, energy from fuel is simply converted into electrical energy, while in the combined heat and power (CHP) systems, fuel energy, in addition to generating electricity, also generates thermal energy. Therefore, the efficiency of these systems is considerably higher than traditional systems, and this justifies the need for CHP systems. The emergence of CH...

Power system restructuring has increased the take part distribution side of power system in providing power. Extensive influence of distribution resources for generation power in distribution side of power system and transferring power electricity between retailer and household consumers are the reason of that.  Among  different types of distributed resources, micro combined heat and ...

در این پایان نامه به بحث و بررسی تولیدات پراکنده و علی الخصوص نیروگاه های تولید همزمان برق و حرارت (combined heat and power) از جهت مقوله جایابی در سیستم های توزیع پرداخته شده است. جایابی dg در سیستم توزیع می تواند با در نظر گرفتن کمیت های مختلفی صورت گیرد. تابع هدف در جایابی dg در اینجا شامل سه ترم کاهش تلفات، بهبود پروفیل ولتاژ و پایداری ولتاژ می باشد که با استفاده از روش های بهینه سازی، بهتر...

The growing worldwide demand for less polluting forms of energy has led to a renewed interest in the use of micro combined heat and power (CHP) technologies in the residential sector. The operation of micro CHP system results in simultaneous production of heat and power in a single household based on small energy conversion units. The heat produced may be used for space and water heating and po...

Optimal operation of the combined heat and power system (CHP) depends on the degree of its flexibility and type of operation. So, the financial and technical challenges both in choosing and economic operation of these systems will be raised. In this paper, at first, a CHP system, including auxiliary boiler, absorption and auxiliary cooling system, has change to a flexible system by adding therm...

By the recent growing of global trend for decentralized power generation via natural gas, the interest in joint operation of several energy carriers has substantially increased. The most significant concept in this regard is the "Energy Hub", which in this paper is employed to supply electrical and heat demands via electricity and natural gas carriers. Transformers, furnaces, combined...
