Description
technical field [0001] The invention relates to a control experiment system of a wind-solar-storage microgrid, in particular to a household off-grid wind-solar-storage microgrid control experiment system. Background technique [0002] As environmental problems and energy problems continue to worsen, the country has supported new energy from a strategic level. Especially following the rapid development of centralized photovoltaic power plants, the state began to subsidize distributed power generation. With the support of the state, household photovoltaic power generation has achieved unprecedented development, and more and more household off-grid wind-solar-storage micro-grids have begun to settle in households. [0003] According to the difference in the way of accessing the power distribution system, microgrids can be divided into household-level microgrids, feeder-level microgrids and substation-level microgrids. For households that are closer to the load side, they are ...
