Detection and Identification of Voltage Dips for the Control of a Photovoltaic Energy Generator Connected to the Distributed Electrical Network

This paper presents a procedure to implement a voltage dip detector to be applied in the control strategy of a photovoltaic energy generator connected to a distribution grid. The most common way to mitigate the number of incidents and conserve nature is to introduce renewable energy sources to the electrical grid, such as photovoltaic systems. However, when these systems are connected to the network, mutual impacts have been introduced, and a thorough investigation of their effects on the influence of the distribution networks/and their potential effects on the effects of photovoltaic systems experienced in network disturbances and steady-state. The connection of photovoltaic sources can have a great impact to power quality such as harmonic injection, short-circuit current, phase imbalances as well as to voltage and protection. It is essential to consider the increase in energy losses and fault currents, particularly during short-circuits. Overview Provides an overview of the types of incidents that impact the service, approach that brieflly explains how a system can detect different dip types based on their simulations Checked, this will help to understand how to detect the different styles voltage dips. It also presents a new technique for encoding the gathered information.
