Summary:With more penetration of solar power plants, photovoltaic generation will be exerting more influences on the power system. The main purpose of this paper is to study the dynamic characteristics of the power system with photovoltaic generation. First, power flow and bus voltage variations of the system with photovoltaic generation are calculated. Then according to the related interconnection criteria, the voltage variation and cable loading are inspected to determine whether the system complies with relevant specifications. Finally, the dynamic responses of the system are analyzed. This paper focuses on a sample power system with photovoltaic generation. The system dynamic characteristics are examined when three-phase faults occur, and the system voltage variations subject to illumination change are investigated. Results show that photovoltaic generation has less impact on system because the capacity of the photovoltaic generation is not high. The illumination change does affect both voltage and frequency of the system, and the system will return to a normal operating state after a period of time.
