研究目的
Investigating the effect of high penetration of photovoltaic (PV) power plants on power system stability under different disturbance conditions.
研究成果
The integration of PV power plants into the power system leads to higher instability and unreliability, especially under disturbance conditions. Control systems like VSC and MPPT are crucial for maintaining stability.
研究不足
The study assumes PV power plants cannot generate reactive power, which may not account for all real-world scenarios. The simulation time for some cases may not be sufficient to observe long-term stability.
1：Experimental Design and Method Selection:
The study involves modeling PV power plants and integrating them into the IEEE 39 Bus system to observe their impact on system stability under various disturbance conditions.
2：Sample Selection and Data Sources:
The IEEE 39 Bus system is used as the base model, with modifications to include PV power plants.
3：List of Experimental Equipment and Materials:
PV power plant model, MPPT controller, VSC, DC-DC boost converter, AC-DC inverter.
4：Experimental Procedures and Operational Workflow:
Simulation of the system under different disturbance conditions (three-phase fault, tripping of load and generator) to observe dynamic behavior.
5：Data Analysis Methods:
Time domain transient simulation to analyze voltage profiles, active and reactive power.
