Abstract:

In recent years, the increasing use of renewable energies is led to the development of gridconnected power plants. However, poses the risk of a high penetration network instability when the generation of power plants will not be able to support the net. Therefore, network stabilization, which is dependent on the system or grid of the country plays an important role and has been strengthened by various grid codes. Against this background, VDE-AR-N 4105 for photovoltaic (PV) systems with the low voltage network and the German Association of Energy and Water (BDEW) connected turned the medium voltage grid code for connection of power plants to the grid and they are the highest certifications In this paper, the control strategy of the generation system with VDE-AR-N 4105 and BDEW Grid Code, in which both active / reactive power control is improved. Simulations and experimental results of the 100-kWPVinverter shown to verify the effectiveness of the proposed control strategy implemental. Large-scale PV inverter systems are connected to the lowvoltage (LV) and/or medium-voltage(MV) grids, but each country has its own system-type or grid characteristics. Thus, LV and MV grid-code certifications are important issues in large-scale PV inverter systems. Normally, the well-known current control scheme is used in PV systems for providing the maximum available active power from the PV array to the grid
