Abstract:
1. A system comprising: at least one electrical energy storage unit (EESU) coupled in series between a utility power grid and a load, the EESU comprising a composite material and a plurality of electrodes, the composite material comprising a high-permittivity ceramic material dispersed in a plastic matrix; a plurality of solid-state switches coupled between the at least one EESU and the utility power grid, wherein the at least one EESU is configured to receive electricity from the utility power grid according to an activation state of at least one of the plurality of solid-state switches; and a control computer coupled to the at least one of the plurality of solid-state switches, wherein the control computer is configured to adjust the activation state of the at least one of the plurality of solid-state switches; and a current limiting circuit coupled between the at least one EESU and the utility power grid, wherein the current limiting circuit is further coupled to the control computer.
