Analysis of the Performance Indicators of the PV Power System

The energy assessment of the PV power systems is carried out by using different types of performance indicators that benchmark the output of these systems against the PV panel maximum output at hypothetical operation conditions. In this paper, a comparative analysis of six types of performance indicators is conducted and a new performance indicator which considers PV panel slope and orientation is proposed. The proposed indicator is benchmarking the PV system actual output against the maximum output of the same system if it would operate in two axis tracking mode. The proposed performance indicator is used to develop a friendly user calculator of PV system output that can be used by, energy providers and PV system installers to evaluate the output of the PV grid connect network. The advantage of the developed calculator is high-lighted by a case study that estimates energy capacity of different residential rooftop PV systems installed in a residential suburb in Sydney.

农村发展光储直柔新型建筑配电系统的商业模式与政策建议

以农村屋顶光伏为基础的光储直柔新型建筑配电系统,可充分利用屋顶闲置资源,提高农村电网可靠性、提高建筑电气化和居民生活水平。在对农村地区光储直柔新型建筑配电系统投入产出分析基础上,提出一种“只出不进、寓电于农”的商业模式,建议以村为单位,分期分批统一建设,总结形成可复制可推广经验,以点带面,多领域多层次推动“零碳乡村”发展。

屋顶光伏为基础的农村新型能源系统战略研究

当前我国农村仍然面临着经济发展、清洁用能、环境保护、减少碳排放等多重问题,文中对我国农村地区发展屋顶光伏系统的资源潜力、技术方案、融资模式和重要意义进行了深入探讨和定量分析,结果表明,我国农村地区面临着能源、环境、经济发展的多重问题,“双碳”战略给解决“三农”问题提供了新的发展契机。发展以农村屋顶光伏系统为基础的新型农村能源系统是解决“三农”问题、实现乡村振兴的重点工作,也是我国建成新型电力系统、实现能源系统低碳转型的突破口和着力点。
