The invention discloses a Stirling engine power generation and energy storage and release method applicable to an isolated island of electricity. A large number of family power grids cannot be laid to homes in a mountainous area and an underdeveloped area. A combustion furnace is used for heating a stainless steel heat storage pot, so that a Stirling engine generates electricity; a Stirling engine output power source storages energy of a mixed energy storage system; the mixed energy storage system is composed of a supercapacitor set, a lithium iron phosphate battery pack, a two-way DC / DC controller and a status monitor; a full-digital DSP discharge inverter and a 48V direct current bus are connected in parallel, after inversion of the full-digital DSP discharge inverter, the output voltage is 220V power frequency alternating current to be used by a user. Electricity sent by a Stirling engine electromechanical thermal combined supply device is subjected to rapid energy storage, and meanwhile the stored electric energy is converted into a power frequency power source with the good quality through the full-digital DSP inverter so as to meet the requirement for household illumination and small household appliances; as long as biomass fuel exists, power generation and energy storage can be performed at any time, and remote farmers can end life with no electricity.
Description
Technical field [0001] The invention belongs to the field of power generation and energy storage and discharge of electric power islands, and relates to a method for generating and storing energy of a Stirling machine that can be applied to power islands. Background technique [0002] Recently, in some areas with special geographical distribution, such as mountainous areas and underdeveloped areas, a large part of household power grids still cannot be installed in the households in a short period of time. The quality of life and production of the people have been seriously affected, and the economy and culture are generally backward. The reasons why this kind of phenomenon has not been fundamentally solved so far are as follows: the wind farm conditions required for wind power generation are relatively harsh and difficult to apply; the solar energy density is low, the stability is poor, and the power supply of solar power generation is very unstable; clean gas resources are not av...
