The Seeker for this challenge is looking for new power electronic components or balance of plant (BoP) elements related to the inverters to increase short circuit power of battery energy storage systems (BESS), improving their capability to be integrated in the current protection scheme of distribution and transmission networks.

This Theoretical Challenge requires only a written proposal.



Lithium ion battery energy storage systems (BESS) are usually installed into power generation plants, distribution and transmission grids.

During the operation of power grids, short circuit events can occur, which are detected by specific protection devices, based on short circuit current flowing into the grid. Conventional systems to detect short circuit events are designed to measure very high current flows, due to the traditional nature of grid generators, with high short circuit current (typically 6-8 times In). However, power electronics used in BESS systems can manage only its nominal power and have no protective systems so, in case of a short circuit event they inject β€œIn” into the grid leading to possible failure of protective devices.

Conventional systems are not suitable. Hence, the Seeker is looking for new power electronic components or BoP elements to increase short circuit power of BESS, improving their capability to be integrated in the current protection scheme of distribution and transmission networks.

This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker.

To receive an award, the Solvers will not have to transfer their exclusive IP rights to the Seeker. Instead, Solvers will grant to the Seeker a non-exclusive license to practice their solutions. 

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on January 21, 2018. Late submissions will not be considered.

What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is a Theoretical-Licensing Challenge?

An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service.

This Challenge is a Theoretical-Licensing Challenge, meaning that the Seeker is requesting non-exclusive rights to use the winning solution. By contrast, Theoretical-IP Transfer means that Solvers must relinquish all rights to the Intellectual Property (IP) for which they are awarded. For these forms of a Theoretical Challenge, Solvers that do not win retain the rights to their solution after the evaluation period is complete. The Seeker retains no rights to any IP not awarded.
