The Distributed Energy System ( Des ) - 774 Words

The attention on the distributed energy system (DES) has grown considerably over the last few years. In comparison to the conventional centralized large-scale power plant, the DES shows great advantages by offering end users a diversified energy supply, higher power efficiency, lower transmission and distribution losses and lower pollutant emissions. DES typically is a suite of on-site grid-connected or stand-alone energy system and has various types such as combined cooling, heating, and power plant (CCHP), biomass-fueled plant, solar power plant and wind power plant et al [1][2]. It is widely applicable in industrial plants, commercial and resident buildings, with energy efficiency and economic competitiveness [3]. In spite of the significant development of DES, the rational design and management of DES, that could maximize the economic and efficient saving benefits, is still a complex and challenge task. In order to meet end-users’ energy demands, the DES design requires a reasonable determination of system structure and configuration by selecting appropriate equipment including their capacities and number. On the other hand, the optimal management of DES is demanded, and therefore, the operating strategies including operation status and load allocation of equipment need to be determined. In order to address the aforementioned task regarding the DES design and management, mathematical modeling or simulation has been used widely to evaluate the characteristics andShow MoreRelatedPower System Essay984 Words   |  4 PagesThe Distributed is electrical power generation in small scale (usually 1MW to 50MW) near the load centre using either conventional techniques such as Diesel generators and micro turbines or using non-conventional techniques such as Photo-Voltaic, wind turbines and small hydro power. This modern concept of power system is very advantageous as it reduces the load on the grid, consumers get a reliable power of better quality, and consumers can supply surplus power to the grid and earn a considerableRead MoreWhat Is Routing Overhead Of The Network1056 Words   |  5 Pages 6- CONCLUSION In this paper, we propose a reliable energy efficient and structure free data aggregation protocol for WSNs. In the EEHM, we consider the sensing region divided into different subregions that are sensed with different reliability requirements. Our proposed protocol allows a selected number of senders to transmit the sensed data depending on the reliability requirement. This not only saves the energy consumption of the sensors but also decreases the traffic load in theRead MoreRenewable Resources Wind Energy Is An Important Factor For The New Era Of Power Quality1568 Words   |  7 Pagesenvironmental issues is attaining importance, generation of power using renewable energy resources is rapidly increasing. Among renewable resources wind energy plays a prominent role. Presently wind energy is receiving a special attention of scholars as it is being non-effecting energy and clear green energy. Power generation using wind energy is increasing promptly. Proper arresting of the wind energy can absolutely aid to meet the energy needs.
