Protection issues of Power Systems with PV Systems Based Distributed Generation
نویسنده
چکیده
The main purpose of this paper is to discuss the basic understanding of active and reactive power flows in photovoltaic (PV) based distributed generation injected power system and how these power flows will influence the performance and stability of a power system. the harmonic currents injected into the utility grid may be a serious problem since they could lead to unacceptable levels of wave shapes distortion, power reversals and voltage regulation The proposed technology is to inject scheduled amount of real and reactive powers in to the grid while maintaining the balance between input and output powers, to protect the power system against the voltage fluctuations, voltage imbalance, power reversals, high short circuit current, harmonic distortion. A grid connected photovoltaic system is modeled and simulated using Matlab/Simulink. Keyword: Active power Distributed Generation, Photovoltaic System protection issues, Reactive power
