Abstract: Various embodiments disclosed herein generally relate to methods and systems for real-time, or near real-time, balancing of an electrical distribution grid. According to at least one embodiment, there is provided one or more local balancing systems, each comprising: an energy storage unit (ESU) operable to store direct current (DC) power; a power converter comprising a DC side and an AC side, the power converter being operable to convert between single-phase (AC) power and DC power, wherein the DC side is electrically coupled to the ESU and the AC side is electrically couplable to at least one secondary distribution block in a secondary distribution grid; and a local controller coupled to the power converter and operable to control the power converter to convert between DC power and AC power.

Abstract: A direct current (DC) power secondary distribution system is provided. The system comprises at least one first conversion unit and a one or more second conversion units. The first conversion unit receives alternating current (AC) electrical voltage from a distribution transformer of an AC power distribution system and converts the AC electrical voltage to DC electrical voltage output. The one or more second conversion units are connected downstream of the first conversion unit, and each second conversion unit converts the DC electrical voltage output from the first conversion unit to a respective AC electrical voltage output for a respective one or more loads. The one or more loads may be associated with a household.
