Redundancy configuration design of DC power router based on demand side response

Power router is the key equipment in the future energy Internet, and its reliability is related to the safe and reliable operation in the future. In order to ensure the operation effect of the router, a redundancy configuration design method of DC power router based on demand side response is proposed. The configuration of redundant sub modules can improve the reliability of the device. Based on the current mainstream power router topology, this paper analyzes and compares the reliability of equipment under different redundancy control modes, introduces the cost loss objective function to optimize the redundancy configuration, studies the solution of the minimum objective function under different conditions, and obtains the redundancy configuration scheme with the best reliability and economy. Finally, through the analysis and calculation of an engineering example, some suggestions are given for the sub module selection and redundancy configuration, which verify the feasibility and effectiveness of the proposed method.
