Electric vehicles (EVs) play a crucial role in achieving sustainability goals, mitigating energy crises, and reducing air pollution. However, their rapid adoption poses significant challenges to the power grid, particularly during peak charging periods, necessitating advanced load management strategies. This study introduces an artificial intelligence (AI)-integrated optimal framework designed facilitate fast mitigate grid stress by smoothing “duck curve”. Data from Caltech’s Adaptive...

In many industrial settings, momentary power disruptions commonly occur, resulting in tripping of large electric machines, which then have to be brought zero speed before the machine can restarted. This result frequent interruptions an process, negative effects on productivity. A more practical approach would restart back original as soon is restored, not having wait for at a standstill. concept known flying restart. this paper, we propose implement permanent magnet synchronous machines...

Unlike conventional servers housed in a centralized and secured indoor environment (e.g., data centers), Internet-of-Things (IoT) devices such as sensor/actuator are geographically distributed may be closely located to the physical systems where IoT utilized. However, resource-constrained nature of limits their capacity deploy sophisticated security solutions. The proposed approach assumes that device can compromised hence, need able automatically isolate device(s). In order enforce policies...

Frequency-domain terminal-behavioral modeling of ac systems is unquestionably attracting more and interest in engineering practice. New electronic power distribution built for airplanes, ships, electric vehicles, data-centers even homes, dominantly comprise a variety electronics converters with very different dynamic characteristics. If their behavior not examined carefully before system integrated, instability can become one the major concerns. This paper addresses low-frequency three-phase...

The integration of single-phase microgrids (MG) and unbalanced loads to three-phase MGs results in power quality issues at the point common coupling (PCC).

Scalable coordination of photovoltaic (PV) inverters, considering the uncertainty in PV and load distribution networks (DNs), is challenging due to lack real-time communications. Decentralized inverter setpoints can be achieved address this issue by capitalizing on abundance data from smart utility meters scalable architecture artificial neural (ANNs). To end, we first use an offline, centralized data-driven conservative convex approximation chance-constrained optimal power flow (CVaR-OPF)...

The growing penetration of distributed energy resources (DERs) has increased the complexity power system due to their intermittent characteristics and lower inertial response, such as photo voltaic (PV) systems wind turbines.
