Heat recovery and storage installation in large-scale battery systems for effective integration of renewable energy sources into power systems

摘要: Abstract The large-scale battery is a promising solution to reduce the wind and solar curtailments, while some electricity will be dissipated heat wasted inevitably. In this contribution, recovery thermal energy storage (TES) subsystem are introduced system recover generated by satisfy part of load concurrently. By applying newly proposed power flow method in transfer analysis together with traditional method, mode integrated electric established, then optimized curtailment. results present that introduction TES could supply certain percentage residents recovering from decrease coal consumption plant combined simultaneously. Meanwhile, mass rate conducting oil keeps high most time drops near zero when switches between charge discharge. Furthermore, alternation frequency has lower bound for normal operation.
