Grid-connected control system for photovoltaic power station

Abstract

A grid-connected control system for a photovoltaic power station. The system monitors the voltage, current, and temperature data of the battery array in real-time and utilizes intelligent algorithms for data analysis and decision-making. It first calculates the overall voltage and average voltage of the battery array and evaluates the status of battery units based on preset thresholds. For low-voltage battery units, the system disconnects and replaces them through the controller module to ensure stable output voltage from the photovoltaic power station. Additionally, the remote monitoring and communication module enables real-time data monitoring and transmission of fault alarm information, enhancing the system's flexibility and reliability. This system is applicable to photovoltaic power stations of various scales and requirements, ensuring efficient and safe delivery of electrical energy to the grid, thereby providing robust support for the widespread adoption of photovoltaic power generation.
