The Design And Research Of Three-layer Mirco-grid System’s Control Based On Embedded Platform

Micro-grid with strong and stable, self-healing, compatibility, significant economic benefits and high integration, is an important technical proposal to solution the access and scheduling management problem of Distributed Generation (DG). But the instability problem include randomness, intermittent work and power change quickly of DG in the micro-grid influence increasingly prominent with increasing proportion of used. Micro-grid control technology has become an important means to solve the bottleneck problem of large-scale application of renewable energy sources. Because of its run independently and coordinated control, Multi-agent System (MAS) is suitable for research the micro-grid. It is open up a new ideas to put the multi-agent technology used in the research of micro-grid.In this paper, the program design a micro-grid system architecture with three-tier based on MAS. Decentralized the control to each agent of all levels used by multi-agent technology. The DG and load as a controllable devices of platform embedded platform, we can managed it. The program complete design a three-tier micro-grid system architecture and the control strategy with grid-connected mode, island mode and emergency mode. Built hardware platform includes design, testing, PCB layout and production of various module. And by the software design to be implemented the control strategies on the hardware platform. The program test the system platform and control strategies with the data modeled of Yunnan Power Grid. The results show that the method of Stratified Control based on multi-agent technology can better control and management of micro-grid. This program is provide some basis to the research of micro-grid.
