A kind of photoelectric storage electrolytic power system and control method thereof

Abstract

The present invention provides an optical storage electrolysis power supply system and a control method, comprising: a photovoltaic power generation system, which includes a photovoltaic cell array and a Boost boost chopper circuit, the output end of the photovoltaic cell array and the input end of the Boost boost chopper circuit connected; an energy storage battery pack, which includes a plurality of series-parallel connected energy storage battery units; a DC / DC converter, which includes a plurality of parallel-connected Buck circuit modules. In the present invention, the DC electric energy output by the photovoltaic power generation system is directly used in electrolytic copper foil, electrolytic aluminum, electroplating and other direct current power consumption enterprises after fewer electric energy conversion links, which can improve energy utilization efficiency and reduce production costs of enterprises.

Description

technical field [0001] The invention relates to the technical field of power supply systems, in particular to a power supply system for optical storage electrolysis and a control method thereof. Background technique [0002] With the acceleration of social and economic development, global energy consumption is increasing, how to make full use of clean energy such as photovoltaic power generation and improve the power conversion efficiency of electrical equipment is becoming more and more important. At present, electrolytic power supplies widely used in the production of electrolytic copper foil, electrolytic aluminum, electroplating and other enterprises have multiple power conversion links, resulting in large power conversion losses in electrolytic power systems. In addition, almost all existing photovoltaic power generation systems convert the output DC power into AC power and then send it to the grid, and then the electrical equipment converts the AC power into the form o...
