China is one of the largest energy consumers in the world. Excessive consumption of coal and other primary energy causes serious environmental pollution and energy crisis. China must wean from the over-reliance on coal and needs to make great efforts to develop clean and efficient renewable...

Hybrid electric vehicle (HEV) is a kind of new cars with low fuel consumption and low emissions, which combines the advantages of traditional vehicle's long endurance and no-pollution of pure electric vehicles. It represents the future direction of development of vehicle for a period of time....

Проводится исследование управляемой марковской системы массового обслуживания M/M/n*/N*. На траекториях управ-ляемого полумарковского процесса строится...

Wind has been recognized as one of major realistic clean energy sources for power generation to meet the continuously increased energy demand and to achieve the carbon emission reduction targets. However, the utilisation of wind energy encounters an inevitable challenge resulting from the nature...

The Li-ion battery is becoming the optimal choice for the Electric Vehicle’s (EV) power supply. In order to protect the Li-ion battery from charging damage and to prolong the battery’s life, a special control strategy based on the dynamic balanced point along with a non-dissipative equalizer...

In the last few years, there is a strong trend towards decentralised production and supply, leading to a situation where a growing number of small and medium size producers will be connected to energy networks. But at the same time, the power quality of the generation must be ensured and this...

The pitch control of wind generators is usually made by a feed back control concept. However, under the conditions where a wind speed changes very frequently due to geographic reasons of the site and the target system has large rotor inertia, the feed back signal which is applied to the control...

A numerical simulation model is developed to study the thermal performance of an outdoor test-room with one Transparently Insulated (TI) wall. The thermal behavior of the room is examined under different control strategies for the shading device. Simulation results indicate significant energy...

A control strategy for the operation of desiccant air-conditioning systems is proposed in this work. The proposed strategy consists of a basic scenario, while some alternative strategy schemes are also proposed on the basis of the approach adopted for the controlling of the humidifiers or the...
