Benchmarking of Hybrid Thermal and Electrical Storage for Renewable Energy Communities

Abstract

Renewable energy communities (RECs) facilitate the local synergy

between different energy forms and offer an opportunity to couple electrical and

thermal energy demands with local renewable energy sources and locally sited

thermal and electrical storage. This application presents a complex integration setting

for the assessment of hybrid energy storage, motivating the development of a new

assessment and benchmarking framework. This chapter will revisit relevant electrical

and thermal storage technologies suitable for REC integration and hybrid energy and

storage systems. A benchmarking framework for application-level assessment of

hybrid energy storage systems is proposed. Requirements and relevant KPIs for the

REC application of a multi-domain hybrid storage system are identified. To demon-

strate the benchmarking framework on the REC application, a complete reference

implementation is presented, including configurable system inpucts, optimisation

and simulation modules as well as a calculation module for performance indicators.

A showcase of the reference benchmark is computed and analysed.
