CIRCE’s EEEIC 2024 paper on optimal RES sizing for Energy Communities
Local Energy Communities (LECs) are at the core of the Energy Transition since they can enable end-consumer participation and lead the path to a bottom-up decentralised Energy Model.
Within DATA CELLAR, we are creating software tools to empower LECs to understand energy consumption and market participation fully. One of these functionalities is an optimal RES sizing tool that allows LECs and households to understand how much PV power and/or Battery storage they should install in their homes.
Presentation of paper at the EEEIC Conference
In June 2024, our partner Luis Luengo from CIRCE, had the opportunity to present his work at the 2024 IEEE International Conference on Environment and Electrical Engineering and 2024 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe). In this paper, the methodology where dynamic price-based signals are considered to obtain the optimal size of the system according to the minimum LCOE is presented. The paper describes the behaviour of the algorithms, the rules of the Energy Management System and compares the results of some predefined scenarios.
The optimal RES sizing tool allows LECs and households to understand how much PV power and/or battery storage they should install to cover their consumption needs. By introducing historical time series of consumption, energy prices and PV radiation, the tool iterates over multiple scenarios’ combination until the optimal size is determined. The algorithm, which performs hourly calculations, considers the expected PV production as well as battery charge and discharge patterns. It also evaluates the income from the sale of excess energy to the grid, according to the provided energy prices. The result of the simulation is the appropriate size of assets and buying/selling strategies to ensure the minimum cost of energy over the lifetime of the assets.
The paper was developed with the collaboration of the co-authors Marcos Remiro, Roberto Rocca, David Miguel Rivas Ascaso, Gregorio Fernández Aznar and Lorena Elorza Uriarte.
CIRCE as a partner of DATA CELLAR
CIRCE Technology Center is an R&D institution that promotes sustainability and energy efficiency. Its main activity focuses on developing innovative technologies and technical solutions to optimize the use of energy resources, foster the energy transition, and combat climate change. CIRCE collaborates with companies, institutions, and international organizations in areas such as renewable energy, energy management, circular economy, and sustainable electrification, aiming to drive innovation for a cleaner and more efficient future.
In DATA CELLAR, CIRCE develops a holistic DSS tool for the development of energy communities, enabling new market roles, market participants, and the configuration of energy communities. Additionally, it contributes to the creation of policy documents aimed at establishing a unified data space and data standards, facilitating access to energy data and promoting business opportunities related to energy communities.
