Abstract: Introduction was made to the third order dynamic equivalent model for a kind of lead-acid storage battery. the parameters of capacity, main circuit branch and thermal model were calculated by the battery discharge test, and based on the PSCAD/EMTDC simulation platform, the third order dynamic model for the lead-acid storage battery suitable for the direct current (DC) distribution network was built, as well as the grid connected model of the energy storage unit connected to the DC distribution network. The experimental platform of the energy storage unit connected to the DC distribution network was set up. The test results verify the effectiveness and feasibility of the constructed grid connected model.
Key words: DC distribution network; lead-acid battery; energy storage converter
