The University of Ghent has developed the STEPS energy storage simulation tool. This powerful web-based application is designed to assist users in determining the optimal size for energy storage systems. Developed with a strong focus on accuracy and practicality, the free tool offers valuable insights for both commercial users and academic researchers.
Based on real battery data
The STEPS energy storage simulation tool operates fundamentally different from existing applications. Traditionally, the determination of the optimal size of a battery system relies on rule-of-thumb approaches. But optimal battery size is a complex and individualized matter that cannot be easily translated into simple rules. The current load profile and yield profile are often too diverse to be assessed by generic guidelines. Additionally, the optimal size of storage heavily depends on the specific battery technology being used and the prevailing electricity prices.
In contrast, the STEPS energy storage simulation tool operates based on a real battery model that is fed with a year's worth of data, including both energy consumption and injection. The battery model simulates the entire year, charging and discharging the virtual battery based on the provided data, price signals, and the selected control strategy. Subsequently, the results are analyzed and compared with economic parameters to calculate the extent of the reduction in utility bills and determine the payback period. This process can be executed for 50 different battery sizes simultaneously. Using these results, the tool can identify the most optimal and performant battery size for the application.
User’s benefits
A key aspect of the tool is its consideration of the user's specific needs. By incorporating the actual load and yield profile of the user, the tool can calculate the real energy flows and provide precise results. This also allows users to visualize how the introduction of a battery will affect their current energy profile and understand the resulting energy profile after implementing the battery.
This web tool offers users a powerful solution that provides valuable insights into the potential benefits of implementing a battery storage system tailored to their unique needs and circumstances. By optimizing their storage system, users can effectively manage their energy, lower expenses, and gain increased autonomy from the grid.
Demonstration of the tool
The University of Ghent will demonstrate the tool during the final STEPS event, which will take place the 5th and 6th of July in Kilkenny, Ireland. During this event, not only all project partners of STEPS will be present, but also the advisory committee, which consists of policy makers, scientists and other influential people in the field of energy storage from each country.
