Research on Low-Temperature Aluminium Electrolysis Charging Recovery System of Renewable Energy Cycle Power Generation System

This paper studies a low-temperature aluminium electrolysis charging recovery system of a renewable energy cycle power generation system, which involves the field of renewable energy and aluminium electrolysis. This article research covers wind power systems, photovoltaic power systems, intelligent integrated power coordination control systems, high-purity aluminium production, low-temperature molten salt aluminium electrolysis charging recovery systems, and aluminium-air battery power generation systems. The intelligent integrated power supply coordination control system presented in this paper is electrically connected to the low-temperature molten salt aluminium electrolysis charging recovery system and the aluminium-air battery power generation system to provide reliable power. Aluminium electrolysis takes place at low temperatures in the range of 700–750 °C whereby the anode is an inert anode producing oxygen gas. The metal is of high purity while the current efficiency is in the 90–95% range. The attached aluminium-air battery power generation system is used for wind power and photovoltaic power regulation.
