Abstract: Power grid system and method of determining power consumption at one or more building connections in a power grid system. The power grid system comprises a power grid comprising a mains grid portion; a plurality of building connections, each building connection comprising a first meter configured for metering power imported from the mains grid portion to the associated building and power exported from the associated building into the mains grid portion; for one or more of the building connections, at least one second meter disposed downstream from the first meter relative to the mains grid portion and configured for metering power exported to the associated building from an auxiliary generator; and a consolidation unit configured for determining power consumption at said one or more of the building connections based on readings from the associated first and second meters.

Abstract: System and system for operating a mains power grid, and system and method for determining a frequency response of a PV generator and/or a frequency response of a thermal storage unit to establish a control routine for controlling power output from the PV generator and/or for controlling power consumption in the thermal storage unit. The method for operating a mains power grid comprises controlling the power output from the one or more photovoltaic (PV) generators coupled to the mains power grid and/or controlling the power consumption in the one or more thermal storage units coupled to the mains power grid based on a characteristic response of the one or more PV generators for curtailment of the power output and a characteristic.

Abstract: Method and system for facilitating auditing of power generation and allocation thereof to consumption loads, and a method and system of certifying generation and consumption transactional pairings over a contiguous power grid network. The method of facilitating auditing of power generation and allocation thereof to consumption loads comprises measuring respective power generation time series for one or more power sources connected to a power grid; pairing the generation time series with one or more consumption loads connected to the power grid such that one generation time series is paired with one or more consumption loads and vice versa; and publishing publication data representing power generated by the power sources according to the measured power generation time series and an allocation of the generated power to the consumption loads.
