Renewable Energy Powered Membrane Technology: Energy Buffering Control to Reduce Shut‐Down Events and Enhance System Resilience under Different Solar Days
Source abstract
Abstract
Abstract Fluctuating and intermittent solar energy cause shut‐down and reduce resilience of photovoltaic powered membrane (PV‐membrane) systems. A charge controller based on pre‐set voltage thresholds for supercapacitors (SC) is designed and employed on varied solar days to cope with these issues. Several parameters—number of shut‐down events (#SD), shut‐down duration (tSD) and resilience factor in flux (RFflux)—are quantified. The controller reduces tSD by 37% (partly cloudy) and 12% (very cloudy), and #SD by 2 and 13 events, respectively. During the 90 min fluctuations, tSD is shortened to 1–4.5 min and #SD is reduced by 1–4 events for feed water salinities of ≤7.5 g L−1. Increasing the PV power capacity to 600–1000 W, zero #SD occurs and RFflux rises from 0.3 to 0.8, indicating enhanced system resilience.
