Research on power control strategy of household-level electric power router based on hybrid energy storage droop control

Abstract In the light of user-side energy power control requirements, a strategy for household-level EPR based on HES droop is proposed, focusing on-grid, off-grid and seamless switching process. The system operating states are divided DC bus voltage information with one converter used as slack terminal to stabilize other converters terminals. on-grid mode, GCC main unit achieve stable operation, whereas in PV, LC at different voltages operation island network. Finally, MG developed using PSCAD / EMTDC simulation platform results show that can effectively adjust output each subunit maintain stability voltage.
