太阳能在电力系统中的利用越来越多。由于系统所在地大气条件的间歇性，太阳能发电对发电系统可靠性的影响与传统电源不同。因此，根据光伏在满足能源需求方面的可靠性贡献来评估在电力系统中增加光伏(PV)源的影响是很重要的。本文采用概率方法建立了太阳能公园的功率输出模型。然后建立了太阳能综合电力系统的可靠性模型，并将其用于一系列研究，以评估太阳能系统满足整体系统需求的可靠性和能量贡献。本文对位于不同纬度的太阳能安装点的太阳辐射数据、太阳能发电量和光伏并网时的可靠性贡献进行了分析和比较。结果表明，有能力对位于世界不同纬度的太阳能电源的可靠性和能量贡献进行量化分析。
Solar power is being increasingly utilized in electric power systems. Solar power has a different effect on generating system reliability than conventional power sources due to the intermittent nature of the atmospheric conditions at the system location. It is therefore, important to assess the impact of adding photovoltaic (PV) sources to a power system in terms of the reliability contribution of PV in meeting energy demand. This paper uses a probabilistic approach to develop a power output model for a solar park. A reliability model is then developed for a solar energy integrated power system and used in a range of studies to evaluate the reliability and energy contribution of the solar system to meet the overall system demand. The analysis of solar irradiation data, solar power output and the reliability contributions of PV when integrated in a small isolated power system are presented and compared in this paper using solar installation sites located at different latitudes. The results illustrate the ability to conduct a quantitative analysis of reliability and energy contributions of solar power sources located at different latitudes around the world.
