With the increasing installed capacity of wind power, higher requirements are put forward for the quality of wind power, but the randomness and intermittency of wind power seriously affect its quality and the stability of the power grid. Hydraulic wind power technology replaces the original...

In order to elaborate a cycle of setting the objectives an effort is needed oriented towards a common list of expectations regarding the way in which the team should work and focusing to the clear definition and accomplishment of the objectives (the emergence of the actions and the emergence of...

The combined cooling, heating and power (CCHP) system – a typical representative of the decentralized energy system – has been increasingly attracting attention in academia and industries in recent years, thanks to its distinctive advantages of high system and economic efficiency, and less...

This study analyzes the material utilization flow, including element carbon (C) and hydrogen (H), together with the energy saving ratio to quantify the material utilization and energy conversion in a coal-based polygeneration system producing methanol and electricity. The C utilization ratio and...

Thermosiphon systems heat potable water or heat transfer fluid and use natural convection to transport it from the collector to storage. This type of technology is applied extensively in countries with good sunshine potential. One such example is Cyprus, which is currently the leading country in...

This paper proposes a method to evaluate and optimize inverter configurations for grid-connected PV systems. It is studied by Monte-Carlo analysis that how the inverter configuration and its operation strategy would impact on lifetime energy yield and the levelized cost of energy (LCOE)...

An SOFC (Solid Oxide Fuel Cell) cogeneration optimization study was carried out for one small-scale and one large-scale building under both hot and cold weather conditions. Several different configurations of the SOFC system are operated using a defined set of input parameters to meet the actual...
