Optimised Residential Battery Energy Storage Systems (ORBES)

About this project

<p style="text-align: justify"><span style="font-size: 11pt"><span style="font-family: Calibri, sans-serif">The growing market of small-scale residential renewable energy generation and storage systems, instigates the research and development of energy management methods to handle the problems connected with necessity of delivering and storing more electric power as well as to attain more optimal use of resources and ensure security of supply. 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.</span></span></p> <p style="text-align: justify"><span style="font-size: 11pt"><span style="font-family: Calibri, sans-serif">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.</span></span></p> <p style="text-align: justify"><span style="font-size: 11pt"><span style="font-family: Calibri, sans-serif">The work implies constant data exchange between the project partners to ensure high-relevance of the research. 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.</span></span></p>

Bilateral cooperation results

The donor partner NTNU was critically important solving one of the most complex tasks – multi-objective optimization and development of specialized components. The single stage isolated matrix converters (IMC) technology developed by TalTech have been known for some time but were lacking due to poor characteristics of conventional silicon semiconductors. Thus, transition to novel technology was critically important. Being an expert in the field of semiconductors and high-performance components, the role of the donor partner was crucial in shifting the IMC technology to a new level.
