With the rapid development of global photovoltaic applications in recent years, it is crucial to evaluate the photovoltaic generation capacity to achieve a secure and efficient utilization of photovoltaic resources. This paper proposes an available photovoltaic evaluation method for generation capacity in distribution networks. The evaluation model is based on the optimal power flow model, considering operational constraints with reactive power and voltage limits. A novel multi-segment boundary approximation method is proposed to solve the model and obtain the available photovoltaic generation capacity explicitly. In addition, the effect of hydrogen storage is explored to host the photovoltaic generation capacity of the distribution network. The accuracy and calculation speed of the proposed method is greatly improved compared with traditional methods. Furthermore, the proposed method can promote the utilization of photovoltaic generation and help dispatching, which guarantees security and improves economics in the distribution network. Simulations on the modified IEEE 33-bus system demonstrate the effectiveness of the proposed evaluation method.
