    Abstract: In order to study the impact of photovoltaic access on system operation risk, this paper introduces the method of establishing the probabilistic model of photovoltaic power plant output based on non-parametric kernel density estimation. On this basis, the Well-being framework is introduced, and the operational risk assessment algorithm of the photovoltaic power generation system considering N-1 safety criteria is proposed. Taking the IEEE RTS system as an example, a case analysis is carried out. The results of the example prove the correctness of the system risk assessment algorithm based on the non-parametric kernel density estimation to establish the photovoltaic uncertainty model and the proposed N-1 safety criterion.
    Key words: photovoltaic power generation system; non-parametric kernel density estimation; N-1 criteria; Well-being framework; operational risk
