Abstract:- The increasing penetration of solar photovoltaic (PV) systems in the power grid is creating new challenges for the protection of transmission lines. Line differential relays are one of the most commonly used protection systems for transmission lines, and their performance can be significantly affected by the integration of solar PV systems. This research paper presents a detailed analysis of the behavior of line differential protective relaying in the presence of solar PV systems. The paper investigates the impact of solar PV integration on the performance of line differential relays and proposes strategies to improve their performance.

Keywords:- Solar photovoltaic (PV) systems, transmission lines, line differential relays, protection schemes, fault detection, power grid, distributed energy resources.
