Abstract

The electric power system produced by Photovoltaic (PV) system is being gradually utilized in power system network with different Photovoltaic configuration. The central Photovoltaic inverter system is designed in large scale of solar power. This system has a different impact on system reliability than conventional generation due the intermittent nature of geographical locations and the availability of PV electronic system. It is therefore vital to evaluate the reliability contribution of central PV system in electric power system network taken into account entire PV system components. This project uses a probabilistic and Part-Count approach to develop the output power of central PV system. A developed model is then applied to Small Isolated Power System (SIPS) to study the system adequacy and the capacity credit of installing Photovoltaic units.

电力系统集中式光伏逆变器可靠性评估
光伏发电系统产生的电力系统正逐步应用于不同光伏配置的电网中。中央光伏逆变系统是在大型太阳能发电中设计的。由于地理位置的间歇性和光伏电子系统的可用性,该系统对系统可靠性的影响与传统发电不同。因此,综合考虑整个光伏系统组成部分,评估中央光伏系统在电网中的可靠性贡献是至关重要的。本项目采用概率和部分计数的方法来开发中央光伏系统的输出功率。将所建立的模型应用于小型隔离电源系统(SIPS),研究了系统的充分性和安装光伏机组的容量信用。
