Abstract

The invention relates to a micro-grid power quality control system and method based on edge computing, which belongs to the field of new energy control technology, and solves the complicated and difficult control process caused by the separation of power quality collection, analysis, and control processes in the existing micro-grid system And other issues. The system includes: DSP sampling controller, which collects the power quality data of each node, and transmits it to the MCU analysis module and edge computing module after A / D conversion; the power quality data includes basic power quality data and comprehensive power quality data; the MCU analysis module judges the basic Whether the power quality data deviates from the reference range, if it deviates, generate a control command to control the working state of the inverter; if it does not deviate, judge whether the comprehensive power quality data is abnormal, if it is abnormal, the built-in model in the edge computing module processes the abnormality to obtain The result of the abnormal diagnosis generates a control instruction for controlling the working state of the inverter; the inverter adjusts its own working state according to the control instruction.

Description

technical field [0001] The invention relates to the technical field of new energy control, in particular to a microgrid power quality control system and method based on edge computing. Background technique [0002] Traditional micro-grid control, in order to ensure the stable operation of the micro-grid, the inverter (converter) is controlled separately to adjust the frequency and voltage to ensure the operation of the micro-grid. Data analysis finally forms a solution and installs a treatment device. It is difficult to effectively verify the feasibility of the solution, the treatment effect is single, the process is cumbersome, and the real-time control effect is not obvious. The present invention aims to realize dynamic power quality acquisition, analysis, local control and adjustment on the basis of traditional control, combined with edge computing technology and inverter (converter) multiplexing principle, and reduces the cumbersome process of traditional solutions , im...
