Problems solved by technology
However, solid oxide fuel cells have soft power output characteristics (when the load changes, the output power changes greatly because the power output characteristics are soft, otherwise it is hard power output characteristics), slow dynamic response, slow start, and cannot meet the load with frequent power changes. Therefore, the use of solid oxide fuel cells alone cannot meet the actual production and living needs.

Description
technical field [0001] Embodiments of the present invention relate to the technical fields of high-temperature fuel cells and new energy sources, and in particular to a hybrid battery energy power system and an energy distribution control method thereof. Background technique [0002] The solid oxide fuel cell is an energy conversion device that works in a high-temperature (600-800°C) environment. It can directly convert the chemical energy in hydrocarbons into electrical energy through electrochemical reactions. It has no combustion and mechanical transmission, and is quiet. , clean, high efficiency, long life, wide range of fuel applicability and high energy density, it is known as one of the most promising green power generation technologies. However, solid oxide fuel cells have soft power output characteristics (when the load changes, the output power changes greatly because the power output characteristics are soft, otherwise it is hard power output characteristics), slo...
