Independent photovoltaic-fuel cell-recycled power battery combined power generation and energy storage system

Abstract

The invention relates to an independent photovoltaic-fuel cell-recycled power battery combined power generation and energy storage system, and belongs to the fields of power generation and energy storage. The system comprises a photovoltaic cell module, a PEM electrolytic module, a PEM fuel cell module, a storage battery, a data collection and energy management system, four DC / DC converters, a direct current bus and a wire; the photovoltaic cell module comprises a photovoltaic cell array and an MPPT controller; the photovoltaic cell module enables the photovoltaic cell array to be in the maximum power output state constantly through the MPPT controller; the PEM electrolytic module comprises a PEM electrolytic tank and a hydrogen storage apparatus; and the hydrogen storage apparatus is used for storing hydrogen generated by electrolysis of water of the PEM electrolytic tank and is loaded with pressure in a pressure sensor detection apparatus. The independent photovoltaic-fuel cell-recycled power battery combined power generation and energy storage system is simple in structure, high in efficiency, and solves the problems of pollution and noise in power generation of an internal combustion engine, overlarge occupied volume and high cost of the storage battery of the conventional off-grid type photovoltaic power generation system, and relatively low efficiency and high unit cost of a hydrogen energy storage type power generation system.

Description

technical field [0001] The invention belongs to the field of power generation and energy storage, and relates to an independent photovoltaic-fuel cell-recovery power battery combined power generation and energy storage system. Background technique [0002] my country has a long coastline, islands, isolated peaks and desert areas. From the perspective of geography and natural conditions, most of these unique environments are far away from the grid coverage area. It is difficult to achieve grid coverage due to its isolated geographical location. The lack of electricity, fresh water and fuel supply has seriously affected their life and production. If the traditional diesel engine power generation method is used in these areas, there will be many problems such as loud noise, environmental pollution, difficulty in fuel supply, long supply time, and high supply cost. However, for the transmission line method, there are disadvantages such as long transmission distance, high transm...
