Narrow Results

Aiming at the problems of large data, high communication cost, vulnerable controller and poor expansibility which cause extra energy loss in the current centralized control of micro-grid, a novel topology of smart micro-grid for home applications is proposed. Moreover, a distributed optimization operation strategy based on Gossip algorithm is proposed to optimize the operation of micro-grid. In this strategy, the optimized operation of the micro-grid can be achieved only by exchanging information between adjacent controllers, while the central controller is not required. Therefore, the problems existing in centralized control can be effectively solved, and the control performance of the system is improved, which is beneficial to the micro-grid implementation of plug and play. Finally, the feasibility of the proposed micro-grid structure, model and operation method is verifed by the Matlab/Simulink simulation platform, simulation results are consistent with the consistent with the analysis. This paper aims to design a novel micro-grid for home applications to help achieve the goal of reducing carbon peaking at the micro level.

The Micro-grid Communication Management System with configurable multi-bus interface and multi-protocol processing ability is realized in this paper. It is based on PowerPC and freeRTOS which make its hardware platform and real-time operating system. It can realize the hierarchic processing both of upstream and downstream protocols, and build micro-grid high-speed communication data centre.
