摘要：
To study the impact on stability and security of the power grid that large-scale Photovoltaic (PV) generation systems integrated, the need for new models and simulation methods is increasing. Firstly, in this paper, a novel simplified phasor model is proposed based on the description of common detail model and averaged model for the PV generation system. The structure of the simplified phasor model is described in detail and the related three models are compared from the aspects of simulation speed, simulation step-size sensitivity and simulation results. Then, super real-time simulation (SRTS) is introduced considering the characteristics of time-consuming for long-term performance simulation when large-scale PV generation systems are integrated to the power grid. The principle of SRTS is presented, and the general simulation method for implementation of SRTS is proposed. Finally, the simulation results curried out from different time scales in the real-time platform are shown to demonstrate the correctness and effectiveness of proposed model and SRTS implementation method for the PV generation system.
