The present work describes a Low voltage ride through (LVRT) method for optimizing a photovoltaic fuel cell hybrid
renewable energy system (HRES). The LVRT control approaches were previously studied to apply them to systems such as
Wind Power Generation (WPG) and Solar Energy Generation (SEG), among other things. Photovoltaic (PV) power
generation systems have recently drawn significant interest, with the building of large PV systems or groupings of systems
related to the utility grid gaining a lot of traction. As a result of the significant penetration of photovoltaic electricity into the
system, energy regulatory bodies enact increasingly strict grid rules to preserve grid stability. This paper demonstrates a
large-scale grid-connected solar system along with the associated modeling and control approaches that can be utilized to
improve DC-based voltage levels which can ride-through capabilities of solar power plants. The grid side inverter is
essential for low-voltage driving. In case of overvoltage or under voltage the grid may trip inverter's DC link thereby such
variation should be avoided as much as feasible. The purpose of this research is to incorporate DC-link over and undervoltage
protection into the control loop without raising the cost of the protective device, which is a significant consideration.
In the future, a study of the outcomes using a typical inverter system is also planned. Numerous fault scenarios with
increasing severity are analyzed to show that the comprehensive control system is effective. The most recent grid code for
the distributed generation system is considered.
