Abstract

Abstract: A large number of distributed photovoltaic access grids pose great challenges to the safe and stable operation of the grid. In view of the fact that the dispatching automation system does not realize the real-time acquisition and monitoring of low-voltage distributed photovoltaic data, this paper proposes the station estimation method as an auxiliary means for real-time acquisition of low-voltage distributed photovoltaic power plants, and estimates the comprehensive low-voltage distributed photovoltaic power plants through appropriate algorithms. Access. Through case analysis, the deviation between the estimated value and the measured value is basically controlled within 8%, which proves the accuracy of the estimated model. This method is of great significance for the power dispatching department to strengthen the operation monitoring and statistical management of distributed photovoltaics, and to reasonably arrange the dispatching plan and coordinate the power supply.
