The “Key Technology for Adaptive Control of High-Density Distributed Inverter Systems” project focuses on the research of adaptive function design and evaluation methods for distributed inverter systems, the interactive transmission mechanism and analysis method for power quality of high-density distributed inverter systems, and the distributed inverse Variable system adaptive access technology and parallel control technology for high-density distributed inverter systems, taking high-density local grid access as a research sample, breaking through the design of active power grid functional systems for distributed high-density inverter systems, and proposing high-density The adaptive impedance control technology and voltage robust control technology for distributed inverter systems improve the access operation characteristics of high-density distributed inverter systems. At the same time, it studies high-density distributed inverter systems, parallel power precise distribution technology, and harmonic allocation. The control method realizes the safety and stability of the new distribution system under the condition of high-density distributed inverter system.

The project makes full use of the existing theoretical basis and laboratory test data, combined with the actual business of distribution, and focuses on solving the problem of low reliability, low degree of adaptation, and poor power quality of the high-density distributed inverter system with parallel access to the network, further improving the distribution. The efficiency and reliability of energy-based power generation have increased the scientific nature of distribution networks that accommodate large-scale distributed power sources.
