The conventional approach to electrical Energy Storage System (ESS) assumes an application of a single selected technology, dedicated to fulfil one functionality.

Hybrid ESS, which is proposed in the HyStore project combines two or more battery technologies within one single ESS. This solution allows for an optimization of ESS performance, while providing additional functions. From the user perspective it allows to maximize revenues and extend lifetime of the ESS.

The key advantage of a hybrid system relies on its control method. The HyStore project aims to develop an Energy Management System (EMS) dedicated to hybrid ESS. Optimization algorithms will be employed with an objective to maximize user revenues.

The pilot of a hybrid ESS is operating in KEZO Research Center in Jablonna, Poland belonging to Polish Academy of Sciences. ESS is a functional part of the microgrid including renewables, loads and EV chargers. Hybrid ESS includes leading battery technologies: flow, lithium-ion and lead-acid.
