Abstract: Currently, the Photovoltaic (PV) cloud network is an important research point in energy Internet. From the perspective of the robustness analysis of PV cloud network, traditional robustness index, the relative size of the giant connected component before and after the cascading , which is focused on the giant component, is not appropriate for the distributed PV network because of the big difference between PV generators and large power grid. In this paper, a new index is proposed, the minimum removed nodes number (MRNN), which can make the entire system collapse, to evaluate the robustness of PV cloud network system. The simulation results show MRNN can clearly indicate the system robustness under different parameters.

Key words:

cascading failure, interdependent system, minimum removed nodes number (MRNN)
