Abstract

This study proposes the bridge type fault current limiter (BFCL) and series dynamic braking resistor (SDBR) methodologies to enhance the low voltage ride through (LVRT) capability of the PV plant during network faults. This work also focuses on smoothing out the PV power fluctuation due to variable irradiance. To achieve this, the output power of diversely located identical and small PV plants, instead of a big PV plant in a certain area, is integrated. Simulations performed through the Matlab/Simulink software shows that the terminal voltage obtained from the proposed protection schemes maintains the grid code, and hence the PV systems need not to be disconnected from the grid during fault. It is also seen that smoothing of PV power fluctuation is possible by the proposed integration method. Also, the size of the energy storage required for the diversely located PV system is smaller than that for a big PV plant.
