Advanced solution for the simulation and optimisation of battery energy storage systems
AleaBattery is an R&D project developed by AleaSoft to analyse the viability of battery storage systems, both stand-alone and hybridised with renewable generation.

The project
The growing penetration of variable renewable generation is increasing the need for flexibility in European electricity systems.
In this context, battery energy storage plays an increasingly relevant role, but its development requires tools capable of jointly analysing its operation, degradation, profitability and long-term evolution.
Before the development of AleaBattery, the tools available in the AleaSoft ecosystem did not specifically address the hourly simulation of battery operation, the optimisation of charging and discharging strategies, usage-related degradation, hybrid configurations or the specific financial assessment of these assets.
AleaBattery is being developed to close this technological gap through a specific environment for the analysis of storage systems.
The solution combines long-term hourly simulation, operational optimisation, degradation, hybrid configurations, economic and financial analysis and automatic report generation.
Objectives
The project combines experimental development, energy modelling, optimisation and economic and financial analysis.
Analyse the operation of storage systems based on hourly simulations of long-term market prices, with horizons of up to 30 years.
Define dynamic charging and discharging strategies that take into account market signals and physical constraints.
Incorporate cycles, depth of discharge, ageing and the state of health of the battery.
Analyse hybrid configurations with renewable generation and optimise the sizing of the battery according to the characteristics of the facility and the operation and market scenarios.
Calculate the IRR and payback of the projects, both at project level and at the level of the investor's equity, and carry out sensitivity analyses and stress scenarios.
Develop a modular and interoperable architecture for deployment in different markets.
Generate customisable reports aimed at financing processes.
Compare configurations and scenarios and validate the solution with real data from European markets.
Key information
The change
The innovation consists of integrating into a single environment specific capabilities that were previously not available for the comprehensive analysis of batteries.
Results
The project is structured in four main phases, from the functional design to the pre-operational validation and the preparation for scaling.
Definition of functional specifications, preliminary technical design and list of simulation scenarios and target project types.
Development of the simulation engine, prepared to process a large set of hourly price simulations with horizons of up to 30 years, together with optimisation algorithms, degradation models and technical and economic analysis components.
Validation in controlled environments, generation of an integrated beta version, technical and economic validation report and preliminary user documentation.
Consolidation of results, validation with internal users and experts, stabilisation of the interface, documentation, training, tests with real cases and preparation of a roadmap for future technology transfer.
Impact
The impact is structured in three dimensions: technological, socioeconomic and contribution to the energy transition.
AleaBattery extends AleaSoft's technological capabilities to the specific analysis of storage systems, integrating operation, optimisation, degradation, hybridisation and financial analysis in a single solution.
The project strengthens the internal capabilities in modelling, data science, software engineering and electricity market analysis, and involves the mobilisation of own resources and new technical capabilities.
AleaBattery facilitates the analysis and optimisation of storage systems, a key technology for the flexibility of the electricity system and the integration of renewable generation.
The project has a European scope, both because of its focus on European electricity markets and because of its application to storage projects in different countries and regulatory contexts.
