Abstract: A multi-energy storage device system includes an electric drive coupled to a load, a DC link coupled to the electric drive, and a bi-directional voltage converter having an output channel coupled to the DC link and an input channel. A first energy storage device (ESD) is coupled to the input channel, and a switch is coupled to the DC link and to a second ESD. A system controller causes the switch to couple the second ESD to the DC link for delivering energy stored in the second ESD to the electric drive. The system controller also causes the voltage converter to convert a voltage of the first ESD to a higher voltage and to deliver the higher voltage to the DC link, wherein the higher voltage is greater than the voltage of the second ESD and causes the switch to decouple the second ESD from the DC link.

Abstract: A system includes a control unit having a processor and a communication interface. The communication interface is configured to communicate with one or more charging stations that are electrically coupled to receive electrical power from a power distribution grid and that are configured to selectively charge one or more energy storage devices connected to the charging stations. The processor is configured to generate first control signals for communication by the communication interface to the one or more charging stations to control transfer of reactive and/or active power from the charging stations to the power distribution grid. The control signals are generated based at least in part on a load cycle profile of one or more electric machines electrically coupled to the power distribution grid.

Abstract: An energy generation and storage system includes one or more energy generation assets, one or more energy storage assets, and a system controller. The system controller identifies a plurality of candidate responses to a grid service request. Each candidate response includes a split value that describes a power split between the energy generation assets and the energy storage assets. The system controller determines a plurality of response scores respectively for the plurality of candidate responses based at least in part on a plurality of asset life impact values that describe an impact that the plurality of candidate responses would have on an asset life of at least one of the one or more power generation assets and the one or more energy storage assets. The system controller selects one of the plurality of candidate responses based at least in part on the plurality of response scores.
