Active and Reactive Power Control of Photovoltaic Power Plant Under Normal and Abnormal Grid Conditions

摘要

This paper presents the implementation of adaptive control strategies in photovoltaic (PV) power plants for control of active and reactive power under various conditions. The enhanced performance of the PV system under different environmental conditions and under distorted grid conditions is shown. The PV system behaves according to the stringent grid code and does not get disconnected during a few unhealthy grid conditions. The active power injection to the grid is tracked and it delivers the maximum power according to Maximum Power Point Tracking (MPPT) following the input conditions. The reactive power injection is also controlled and is set according to the need of different grid conditions. The performance analysis of three phase solar-PV system is carried out in the Matlab/Simulink platform.
