Economic viability of cloud energy storage with e-mobility in residential mini-grid: Impact of e-mobility on CES

The rapid expansion of electric mobility (e-mobility) and renewable energy sources (RES) has underscored the importance of efficient energy storage solutions in residential mini-grids. Among these, cloud energy storage (CES) stands out for its flexibility and scalability, which are crucial for meeting the demands of e-mobility while ensuring grid stability. This chapter delves into the impact of e-mobility on CES-enabled residential mini-grids, focusing on their potential benefits, challenges, and implications for sustainable energy integration. The study focuses on a small residential community comprising six houses, each equipped with varying battery capacities and models of e-scooters. The analysis is conducted across three scenarios: (1) grid-connected mode, (2) CES without e-scooter, and (3) CES with e-scooter. Notably, the availability of e-scooters varies among users. To capture seasonal variations, the cost of electricity is computed for both summer and winter days. Results indicate that Scenario 3, involving CES with e-scooters, offers the most cost-effective solution for individual users, outperforming the other scenarios. Moreover, it generates higher revenue, surpassing Scenario 2 by 18.72% in summer and 29.71% in winter, showcasing its potential for enhancing the economic viability of residential mini-grids.
