Distributed Photovoltaic Confidence Capacity Evaluation Based on Distribution Network Reliability Analysis

From the perspective of the reliability of the active distribution network system, the reliability of the capacity of the distributed photovoltaic installation scale is analyzed. Firstly, according to the PV output curve, the characteristics of PV output are analyzed. Furthermore, the relationship between the real-time output power of the PV array and the illumination intensity is considered, and the output of the distributed PV saturation is predicted. Secondly, the sequential state based on system state transition sampling is used. Carlo simulation, evaluation of distribution system reliability with distributed photovoltaics, and gives a distributed PV confidence capacity assessment step; finally, through the effectiveness of the modified IEEE RBTS Bus6 verification method, to guide the development of distributed photovoltaics and the construction of the power grid has certain guiding significance.
