Reservoir combiner system

An energy storage system comprising:

• a housing;
• a plurality of energy storage devices;
• connections for receiving power from selected ones of a plurality of power generation sources;
• a system level combiner for combining the power from the respective energy storage devices and selected ones of the power generation sources to provide system level combined power as an output;
• a reservoir level combiner for combining the system level combined power from a plurality of system level combiners into a reservoir level combined power;
• and
• wherein the energy storage devices are electrically connected through the system level combiner and the reservoir level combiner so that a two-way power transfer path is created between the energy storage devices and each respective system level combiner via the reservoir level combiner.

A reservoir system comprising:

• a plurality of power generation sources;
• a plurality of energy storage systems, at least some of the energy storage systems comprising one or more energy storage devices, the energy storage systems electrically connected to selected ones of the power generation sources;
• a system level combiner in each of the energy storage systems, the system level combiner combining power from the energy storage devices and selected ones of the power generation sources to provide system level combined power as a first output;
• a reservoir level combiner for combining the system level combined power from a plurality of system level combiners into a reservoir level combined power;
• a power conditioning system for receiving, combining, and conditioning the reservoir level combined power for supply to a power network;
• and
• wherein the energy storage devices are electrically connected through the system level combiner and the reservoir level combiner so that a two-way power transfer path is created between the energy storage devices and each respective system level combiner via the reservoir level combiner.
