While demand for electricity continues to grow, expansion of the traditional electricity supply system, or macrogrid, is constrained and is unlikely to keep pace with the growing thirst western economies have for electricity. Furthermore, no compelling case has been made that perpetual improvement in the overall power quality and reliability (PQR) delivered is technically possible or economical...

The thermal balance analysis is a useful method to determine energy distribution and efficiency of internal combustion (IC) engines. In engines cooling concepts, estimation of heat transfer to brake power ratio, as one of the most significant performance characteristics, is highly demanded. In this paper, investigation of energy balance and derivation of specific heat rejection is carried out e...

One of the options to increase the energy efficiency of current electricity network is the use of a Virtual Power Plant. By using multiple small (micro)generators distributed over the country, electricity can be produced more efficiently since these small generators are more efficient and located where the energy is needed. In this paper we focus on micro Combined Heat and Power generators. For...

Existing studies that consider the techno-economics of residential heating systems typically focus on their performance within present-day energy systems. However, the energy system within which these technologies operate will need to change radically if climate change mitigation is to be achieved. This article addresses this problem by modelling small-scale heating techno-economics in the cont...

Power and heat are the primary energies for the industry and communities. Combined heat and power (CHP) is a process of heat and power cogeneration, which is designed to meet the needs of both users. In previous studies of emergy analysis on CHP, the transformity was simply calculated by dividing the total emergy input by the amount of production. The result always showed that transformity of e...

-Waste heat from electronic components in information and telecommunication equipment is not trivial. Especially, contemporary Integrated Circuits(IC’s) in computers, servers and telecommunication equipment dissipate more amount of total energy as heat energy to the environment. Additionally, coolers have to be used in large amount to dissipate the heat from those equipments. Companies often sp...

existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. according to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...

Heat waves have been responsible for more deaths worldwide than all other natural disasters combined. In Europe, this “silent killer” caused 70000C excess deaths in 2003, and more recently 3500C people died during 2 separate heat waves in India (May 2015) and Pakistan (June 2015) (Fig. 1). Groups among the most vulnerable include the elderly, poor, and people with cardiovascular disease. Identi...
