An intelligent impedance injection module is for use with transmission lines in a power grid. The intelligent impedance injection module has a plurality of transformer-less impedance injector units and a controller. The controller changes injector gain of the impedance injector units to compensate for current swings in a transmission line.

A system and related method of generating and utilizing electrical energy flows a gas along a pipeline, generates electricity by reducing the pressure of the gas at selected locations along the pipeline, and operates an energy consumer using at least a portion of the generated electricity.

Systems and methods for identifying optimal siting locations for an energy storage system. Siting locations are identified based on a value index derived from pricing data associated with a plurality of nodes on an electrical grid. An index is derived for each selected node of the plurality of nodes to produce a siting recommendation.

In an energy system in a community provided with a plurality of unit grids, each of which is an energy transfer network of a single-unit facility including a power load, the unit grids each include a photovoltaic generator, supply power generated by the photovoltaic generator thereof to the power load thereof, and, as an electric vehicle moves, form a cooperative grid that transfers power stored in a mobile storage battery mounted on the electric vehicle to and from another of the unit grids, and some of the unit grids whose geographical positional relationship is not fixed form a virtual grid for transferring power as a combination of the unit grids that form the cooperative grids changes in accordance with a destination of the electric vehicle.

In a control device, an instruction acquirer acquires an instruction to suppress in a specified period supplying of generated power generated by power generator installed in a power-consuming area to a commercial electrical power system. Upon the instruction acquirer acquiring the instruction, a water heater controller commands a water heater installed in the power-consuming area to perform a water heat-up operation when a predetermined condition is satisfied in the specified period.

A method and apparatus is described for conveying the amount of loading of a power source to a load control device by controlling the frequency of the AC power output from that power source in a manner that controlled frequency represents the loading. At a different location in the power system, the frequency is measured and the corresponding loading of the power source is used to prevent or alleviate a power source overload.

Certain aspects of the present disclosure relate to virtualizing battery resources for grid service applications. In particular, some of these aspects provide a method for configuring a plurality of virtual energy storage devices in an energy storage device of a fixed energy storage system; and performing two or more grid services concurrently with two or more virtual energy storage devices of the plurality of virtual energy storage devices.
