The invention relates to a circulating system for assisting peak regulation of a thermal power plant by electrolyzing water to produce hydrogen and utilizing multi-path hydrogen and oxygen. The output end of a generator is connected with the input end of a boosting transformer, and is connected to a power grid after boosting; the output end of the generator is also connected with the input end of the step-down rectifying device; the output end of the step-down rectifying device is connected with the input end of the electrolyzed water device; the output end of the electrolyzed water device is connected with the input ends of the hydrogen storage tank and the oxygen storage tank; the output end of the hydrogen storage tank is divided into three paths, one path is connected with the coal-fired boiler; one path is connected with a flue gas denitration system; one path is connected with the generator; the output end of the oxygen storage tank is connected with the coal-fired boiler; and the DCS control system is
