1. 11. Dimensioning and Life Cycle Costing of Battery Storage System in residential housing- A case study of Local System Operator Concept

   University essay from KTH/Elektroteknisk teori och konstruktion

   Author : Shamil Mehdijev; [2017]
   Keywords : Battery Storage; Life Cycle Cost Analysis; Monte Carlo Simulations; Electricity Price; Photovoltaic; Levelized Cost of Electricity; NPV;

   Abstract : growing concern on achieving environmental sustainability and at the same time making economical savings has become a necessity in our society. The prices of different battery energy storage technologies together with PV cells are declining all around the globe which has led to the fact that there is an increased interest in investing and using these technologies to be able to reach environmental sustainability.

3. 12. Membrane evaluation and thermal modelling of the vanadium redox flow battery

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Anders Kronander; [2016]
   Keywords : thermodynamics; Thermal; Simulation; Energy storage solutions; Modelling; VRB; Vanadium; Battery; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

   Abstract : In this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE) and voltage efficiency (VE).

4. 13. Optimization of a Vanadium Redox Flow Battery with Hydrogen generation

   University essay from KTH/Skolan för elektro- och systemteknik (EES)

   Author : Daniel Wrang; [2016]
   Keywords : ;

   Abstract : We consider the modelling and optimal control of energy storage systems, in this study a Vanadium Redox Flow Battery. Such a battery can be introduced in the electrical grid to be charged when demand is low and discharged when demand is high, increasing the overall efficiency of the network while reducing costs and emission of greenhouse gases.

5. 14. Vanadium Redox Flow Battery : Sizing of VRB in electrified heavy construction equipment

   University essay from Mälardalens högskola/Framtidens energi

   Author : Nathan Zimmerman; [2014]
   Keywords : All-vanadium redox flow battery; Vanadium; Energy storage; Batteries; Electric vehicle electrification;

   Abstract : In an effort to reduce global emissions by electrifying vehicles and machines with internal combustion engines has led to the development of batteries that are more powerful and efficient than the common lead acid battery.  One of the most popular batteries being used for such an installation is lithium ion, but due to its short effective usable lifetime, charging time, and costs has driven researcher to other technologies to replace it.

6. 15. Grid Capacity Issues with Distributed Generation

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Nofel Dakhel; Olof Bohgard; [2014]
   Keywords : Technology and Engineering;

   Abstract : Climate change is more evident than ever as reflected in The European union's environmental directives which say that the carbon emission must be reduced by 20% and 20% of the used energy must come from renewable energy sources until 2020. In Germany political decision has been made that the nuclear power will be replaced by renewable energy in long term. READ MORE
