Advanced Control of Battery Energy Storage Systems

Cooperation with ABB Corporate Research Ltd.

Description

An advanced control and design incl. dimensioning system for energy storage systems, in particular with batteries (specifically Li-Ion). The results include:
(a) System design / dimensioning tools for sizing the relevant components, in particular the energy storage (battery) in terms of power and energy, but possibly also other components such as the converters, containers, and other substation equipment.
(b) Advanced control algorithms that take into account the current state of operation of the system and the relevant connected systems (e.g. electrical grid, generation and load), forecasts of these (e.g. load, generation or weather forecasts), the state of health of the battery, a stress model of the battery which accurately reflects the battery aging/degradation during the lifetime, the relevant constraints on the operation (e.g. grid codes, market rules, contract with the TSO). The design tools (a) are aware of the advanced control algorithms, dimensioning / sizing takes into account and simultaneously addresses the relevant controller parameters (joint optimization of the system and the controller). The system was designed for the following use cases: primary frequency control
ramp rate limitation control, peak shaving (e.g. customer peak load shaving).
