Abstract:

可再生能源热电联产技术对于节能减排、改善环境以及实现绿色经济具有积极的意义。太阳能、地热能和生物质能是最具规模化潜力的热电联产可再生能源。本文介绍了国内外可再生能源热电联产技术的发展现状,并对比了各技术的优劣。目前,地热热电联产技术较为成熟,而适应面更广的太阳能热电联产尚处于工程示范和技术开发阶段。基于太阳光谱综合利用的光伏温差发电热电联产技术有望成为下一个研究热点。可再生能源热电联产技术的推广离不开智能电网,而以满足本地用能需求为主,多余电力出售给智能电网的可持续社区将为该技术的大规模推广奠定有力的基础。
The technology of combined heat and power generation on renewable energy (CHP-RE) is of posi- tive significance for energy saving, environment improving and green economy. Solar energy, geothermal energy and biomass energy are the most potential renewable energies for large scale CHP. This paper intro- duced the CHP-RE development at home and abroad, and compared several main CHP-RE technologies. The CHP on geothermal energy is mature, while the CHP on solar energy, which can be used widely, is still in the stage of project demonstration and technology development. The photovoltaic-thermoelectric CHP, based on the comprehensive utilization of solar spectrum, will be the next hot topic in future. The CHP-RE cannot be promoted without smart grid. The sustainable community will lay the foundation for large scale utilization of CHP-RE, in which the needs of local energy are satisfied first and excess electricity can be sold to smart grid.
