Promoting the development of green technologies and replacing fossil fuel vehicles with electric ones can abate environmental anxieties issues associated energy supply security. The increasing demand for requires an upgrade expansion available charging infrastructure to accommodate fast public adoption this type transportation. Ethiopia set a pro-electric cars policy made them excise-free even before first vehicle stations were launched by Marathon Motors Engineering in 2021. This paper presents ever technical, economic evaluation powered hybrid intermittent generation systems three cities Ethiopia. tests model using different battery types: Lead-acid (LA), Flow-Zince-Bromine (ZnBr) Lithium-ion (LI), used individually. Using these technologies, proposed are then compared terms system sizing, economy, technical performance stability. results show that feasible configuration Solar Photovoltaic (PV)/Diesel Generator (DG)/ZnBr provide lowest net present cost (NPC), values $2.97M, $2.72M $2.85M, (COE), $0.196, $0.18 $0.188, Addis Ababa, Jijiga Bahir Dar, respectively. Of all systems, Wind Turbine (WT)/PV/LI, PV/LI WT/PV/LI configurations have highest NPC COE Dar. configuration, demonstrate ZnBr is most favorable choice because parameters, including total COE, found be lowest.

Intermittent renewable energy is becoming increasingly popular, as storing stationary and mobile remains a critical focus of attention. Although electricity cannot be stored on any scale, it can converted to other kinds energies that then reconverted demand. Such storage systems based batteries, supercapacitors, flywheels, thermal modules, compressed air, hydro storage. This survey article explores several aspects First, we define the primary difficulties goals associated with Second, discuss strategies employed for criteria used identify most appropriate technology. In addition, address current issues limitations approaches. Third, shed light battery technologies, which are frequently in wide range applications The usage types batteries described alongside their market shares social environmental aspects. Moreover, recent advances state estimation cell-balancing mechanisms reviewed.

Electricity generation using distributed renewable energy systems is becoming increasingly common due to the significant increase in demand and high operation of conventional power with fossil fuels. The introduction electric grid crucial for delivering future zero-emissions cost-effective promoting facilitating large-scale prosumers. However, these deployments are forcing changes traditional markets, growing attention given transactive networks that enable trading between prosumers consumers more benefits cluster mode. This change raises operational market challenges. In recent years, extensive research has been conducted on developing different local models provide opportunity minimize costs resources by localized management. Local markets a stepping stone toward fully bring adequate flexibility reducing users’ reflecting price grid. Designing stable regulatory framework electricity one major concerns regulation policies efficient reliable delivery power, maximizing social welfare, decreasing infrastructure expenditure. depends changing needs system, objectives, constraints. Generally, optimal design requires both short-term efficiencies long-term efficiency investment quality. this paper, comprehensive literature review main layers microgrids introduced, highlighting role layer. Critical aspects systematically presented discussed, including design, mechanism, player, pricing mechanism. We also intend investigate application ledger technologies trading. end, we illuminate mathematical foundation objective functions, optimization approaches, constraints market, along brief overview solver tools formulate solve problem.

The growing demand for electricity driven by population growth and industrialization is met integrating hybrid renewable energy sources (HRESs) into the grid. HRES integration improves reliability, reduces losses, addresses power quality issues safe effective microgrid (MG) operation, requiring efficient controllers. In this regard, article proposes a prairie dog optimization (PDO) algorithm photovoltaic (PV)-, fuel cell (FC)-, battery-based HRESs designed in MATLAB/Simulink architecture. proposed PDO method optimally tunes proportional integral (PI) controller gain parameters to achieve compensation of load mitigation PQ problems. MG system has been applied various intentional such as swell, unbalanced load, oscillatory transient, notch conditions study response controller.
