Condition Monitoring
A small scale project to determine the feasibility of health indices for EES and to identify an initial methodology.
The objectives of this project are to
  • summarise existing literature of energy storage system technology (e.g. types of batteries, power electronics etc.) for grid storage applications from technical, legislative, environmental and/or economic perspectives which is feasible within the project’s lifespan; 
  • identify a technology, relevant parameters (for instance, age, likelihood of failure, dependability, capacity, system design such as a few large systems versus many smaller systems, usage etc.) and define health condition criteria i.e. significant factors that are key for further investigation in this project;
  • analyse existing state of health monitoring methods, for instance, classification, characteristics, challenges, advantages, limitations, underlying concept and mathematic formulas of individual methods that are applicable to energy storage systems technology; and
  • determine the health index of the chosen technology under study by defining selection criteria, choosing and applying the most suitable health monitoring method in the project.
