VRFB Maintenance Procedures: Technical and Economical Relevance

چکیده
The VRFB system has been largely studied for almost 30 years. Several plants are installed around the world, with power and energy exceeding some MW MWh respectively new companies entering growing market. However, a real widespread application of this technology is hindered by its high capital cost. One method to make these batteries more competitive on market increase their cyclability means appropriate maintenance procedures. In work, review most important realizable procedures impact cost presented, considering both operative economical points view. order evaluate how costs economy, specific indicators have used, in particular levelized storage (LCOS) net present value (NPV). This analysis shows LCOS vanadium redox flow battery decreases as stored E/P ratio increases, case 20-year daily operations. For = 2h between 1.15 1.6 € kWh-1, 12h 0.31 0.41 depending procedure adopted. Moreover, study suggests that an industrial profitable than residential one. Indeed, P 1MW (industrial size) can recover initial investment (NPV 0) ten years sales price 0.38-0.45 which close average EU A smaller system, instead, 6 kW 4h (residential requires higher price, 0.74-0.80 kWh-1. latter become only longer lifetime, hence confirming efficient plays essential role.

Determining economical maintenance intervals
Several models have been proposed for scheduling the preventive maintenance (PM) of complex repairable systems in industry. These are often application-speci"c and some make unrealistic assumptions about stationarity of the process and quality of repairs. We investigate two principal types of general model, which have wider applicability. The "rst considers "xed PM intervals and is based on the...
