Research on Digital Twin Modeling and Simulation Technology for Distributed Resource Aggregation Regulation

Abstract

Virtual power plants need to build awareness, transmission and application of information flow model, require multiple levels between virtual power plant, the virtual power plant each participation main body, regulation and control of virtual power plant and quantification of communication information transmission between the main constraints, this paper studies the distributed resources polymerization technology, the modeling and simulation of mechanical and electrical characteristics of virtual power plant communication network transmission characteristics of digital simulation technology, This paper proposes a simulation method of diversified resource aggregation regulation based on virtual group structure. By collecting the electrical characteristic change curve of each distributed unit, and stacking the transmission characteristics of communication network, digital simulation aggregation is carried out to obtain the digital model of cooperative operation and control characteristics of virtual power plant "information flow + energy flow". Through this model will be connected to Matlab/Simulink power system simulation environment for power regulation and operation simulation verification.
