A power control device for use in an AC power grid for regulating an electrical power a load that is supplied by the AC power grid consumes. The power control device has a frequency sensing functional block for detecting a deviation of the grid frequency from a nominal grid frequency and a logic functional block for performing a load adjustment process during which the power the load consumption is reduced. The load adjustment process is based at least in part on the variation of the frequency of the AC power grid. The load adjustment process is design such that for a plurality of power control devices the individual response produce a grid-wide effect that compensates imbalance between power generation and load in fashion that may reduce unwanted distortion in the AC power grid, such as flicker.

Power control device and related methods

Various configurations of a power plant are described. The power plant is configured to supply power to a receiving electrical grid by the combustion of metal powder. The power plant is also configured absorb power by recovering the metal powder from the metal oxide produced by the combustion of the metal powder, with electricity from a source electrical grid.
