Study of Home Energy Management Systems (HEMS) for Urban Cities

This study dives into the effectiveness of home energy management systems (HEMS) for sustainable energy management and cost savings. HEMS integrates solar PV, batteries, residential loads, power electronics and controls enabling bi-directional power flow between homes and the grid. It explores the cooperation between solar generation, energy storage, and energy demand management strategies, illuminating their combined potential to optimize energy consumption, reduce utility bills, and diminish grid-related challenges. A case study that analyzes the return on investment (ROI) and grid management and energy flow in multiple cities is reviewed, and this is compared with Windsor to understand how the HEMS would impact cities. Lifestyle profiles, specific to energy usage throughout the day, are also investigated to recognize the type of people who would most benefit from HEMS. This information can guide companies and manufacturers toward understanding their targeted audience, as well as aid the audience toward recognizing how their life and energy usage could be improved using HEMS. This review emphasizes the potential of integrated HEMS, highlighting their potential to drive the transition towards a more flexible, localized, and environmentally friendly energy infrastructure.
