As global warming and environmental degradation escalate, transitioning to renewable energy systems (RES) becomes imperative. RES, such as solar and wind power, offer sustainable alternatives by emitting minimal greenhouse gases during operation. However, their integration into existing power grids poses challenges due to their intermittent nature. Local energy communities (LECs) and energy hubs (EHs) address these challenges by locally managing energy supply and demand, enhancing grid stability. This paper explores the integration of thermal energy storage (TES) and battery energy storage systems (BESS) within EHs, utilizing Digital Twin (DT) technology for energy management. DTs provide real-time monitoring, simulation, and optimization, facilitating the efficient use of RES and improving system reliability. The high-level architecture of the DT platform is designed for modularity and scalability, supporting both virtual test environments and real-time operations. The platform incorporates key assets like photovoltaic systems, BESS, TES, heat pumps, and electric vehicle charging stations, and supports various control strategies to optimize energy management. Performance is evaluated using key performance indicators (KPIs) such as CO2 footprint, operational cost, self-consumption, self-sufficiency, and peak power duration, providing critical insights into the sustainability and efficiency of energy systems. A simulation is performed to showcase advanced energy management for integrated thermal - electrical energy storage systems on a residential area of 100 households in reducing CO2 emissions and energy cost.
