Optimised Residential Battery Energy Storage Systems (ORBES)

The project is focused on the area of small-scale residential battery storage, which currently lack flexible energy management systems that can enable their effective coordination and optimal utilisation of their potential. The project aims to address this problem from multiple levels: electronic components, power electronic interfaces and system-wide energy management algorithms. By performing comprehensive analysis and optimisation of the battery energy storage systems at various levels, it possible utilise the most accurate data and deliver high-quality results. The models for forecasting of the electricity demand and supply in the Baltic Sea region from renewable energy sources will allow to create and investigate the energy management profiles that will reveal operating profiles for battery energy storage systems. These profiles are going to be used for research and multi-objective optimisation of power electronic converters, particularly in terms of efficiency and cost. This work will be used as input for further development and optimisation of energy management algorithms to take maximal advantage of battery storage systems. The outcomes will increase the awareness of the feasibility of residential battery storage systems in the Baltic Sea Region. The project will lay foundations for development and assessment of possible business models concerning DSOs, aggregators and prosumers, aiming to reduce life cycle costs, enable effective demand response programs and take the most benefits from this emerging technology.

This project has received funding from the EEA Financial Mechanism Baltic Research Programme in Estonia.
Date: 1 January 2020 - 31 December 2023.
Budget: 750 536 EUR
