Optimization of Size and Operation of Stand-Alone Renewable-Based Systems with Diesel and Hybrid Pumped Hydro Storage–Battery Storage Considering Uncertainties

Batteries, Journal Year: 2025, Volume and Issue: 11(2), P. 70 - 70

Published: Feb. 8, 2025

Currently, the electrical supply in stand-alone systems is usually composed of renewable sources with fossil-fuel generators and battery storage. This study shows a novel model for metaheuristic–stochastic optimization (minimization net present cost, NPC) sizing energy management photovoltaic (PV)–wind–diesel hybrid pumped hydro storage (PHS)–battery systems. The implemented C++ programming language. To optimize operations—thus reducing PHS losses increasing lifetimes—optimal can power limits using or to store energy. probabilistic approach considers variability wind speed, irradiation, temperature, load, diesel fuel price inflation. variable efficiencies components advanced models degradation are considered. methodology was applied Graciosa Island (Portugal), showing that, compared current system, optimal system (with much higher PHS–battery storage) reduce NPC by half, life cycle emissions 14%, expand penetration 96%, reserve capacity shortage zero.

Optimal of Placement for Battery Energy Storage System Installation Using Fuzzy Expert System in Thailand: A Case Study of Critical Closed-Circuit Television Positions

Energies, Journal Year: 2025, Volume and Issue: 18(6), P. 1328 - 1328

Published: March 7, 2025

This paper presents placement optimization for battery energy storage system installation using a fuzzy expert system. Nowadays, the Bangkok Metropolitan Administration (BMA) has installed CCTV cameras surveillance, deterrence, and to record events as evidence legal proceedings. However, in some areas, there is no BESS, so when power goes out, recording cannot continue. article uses Fuzzy Logic Expert System assess critical areas consideration of future BESS Bangkok. The key factors include (1) number image requests from Administration, (2) duration outages BMA, (3) total consumption each subdistrict. study results show that can effectively handle ambiguous data improve decision-making. Latkrabang Lamphlatiew subdistricts have most points where investment appropriate. size was determined based on maximum recorded outage 57 min, with backup design set at 1 h. DIgSILENT program used determine point, which calculated be 160.2 Wh.

Research Progress on the Performance Enhancement Technology of Ice-on-Coil Energy Storage

Energies, Journal Year: 2025, Volume and Issue: 18(7), P. 1734 - 1734

Published: March 31, 2025

Ice-on-coil energy storage technology has been widely used in air conditioning systems and industrial refrigeration as an efficient technology. This paper reviews the research progress of ice-on-coil technology, including its working principle, system design, key parameter optimization, practical application challenges solutions. Three kinds ice melting are introduced. The internal largest cold density slowest rate melting. external lowest fastest combined can have highest a high By comparing results different studies, influence fin thin ring on heat transfer enhancements is summarized. It found that time be reduced by 21% 34% when annular set. Regarding control, adopting ice-melting priority strategy increases operating consumption, but economy improves; using unit lowers suffers slightly. When cooling demand exceeds capacity chiller, control more economical. Some suggestions for future presented, such optimizing shape arrangement coil fins integrated with renewable energy. provides guidance further development
