Description

Technical Field

[0001] The present invention relates to the field of source-grid-load-storage multi-energy complementary integrated energy technology, and more specifically, to a multi-fuel pan-hydrogen gas turbine multi-energy complementary energy system and a design method thereof. Background Art

[0002] Pan-hydrogen gas turbine technology refers to a power generation and energy supply technology that, based on existing gas turbine technology, mixes hydrogen and natural gas or other combustible gases in proportion or uses pure hydrogen fuel to achieve safe, efficient, stable combustion and low-carbon emissions.

[0003] With the rapid development of the new energy industry and new power systems, the pan-hydrogen gas turbine is deeply integrated with the power system in terms of source, grid, load and storage, supporting the large-scale development and utilization of new energy. In terms of power supply, hydrogen can reduce carbon emissions at the power generation end through the combustion of hydrogen or pure hydrogen in gas turbines, and realize flexible regulation of the power generation end; in terms of power grids, hydrogen can be transported over long distances through pipelines, which can be used as an effective supplement to ultra-high voltage power transmission; in terms of load, electrolyzed water can be used as a flexible load to provide flexible response on the demand side, and the pan-hydrogen gas turbine can provide heat, cold and electricity to realize large-scale consumption of renewable energy; in terms of energy storage, hydrogen, as a long-term energy storage means, can realize the mutual conversion of electricity-hydrogen-electricity-heat-cold, which is a long-term energy storage form across days, months and seasons.

[0004] In the prior art, traditional distributed energy stations or hydrogen fuel cell distributed energy stations have the following problems:

[0005] 1. Hydrogen production is expensive, with electricity costs accounting for more than 60% of the total cost;

[0006] 2. Currently, the demonstration projects reported all use hydrogen fuel cell cogeneration, and the local consumption capacity of green hydrogen is limited, so it is impossible to achieve large-scale local consumption of green hydrogen;

[0007] 3. The design of installed capacity of renewable energy green electricity cannot form the "source follows load" principle, that is, it is impossible to determine the installed capacity of green electricity based on the total electricity load demand, which easily leads to a large amount of abandoned electricity.

[0008] In view of the above situation, the present invention provides a multi-fuel pan-hydrogen gas turbine multi-energy complementary energy system. Summary of the invention

[0009] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-fuel pan-hydrogen gas turbine multi-energy complementary energy system and a design method thereof to solve the problems raised in the above-mentioned background technology.

According to the converted value of the heat load, the installed power and model of the pan-hydrogen gas turbine are selected, and the effective power generation of the pan-hydrogen gas turbine can be further determined;

[0021] S3, calculate hydrogen by electricity. According to the effective power generation of the pan-hydrogen gas turbine, the fuel consumption of the pan-hydrogen gas turbine can be calculated. With hydrogen and high calorific value combustible waste gas as the main fuel and natural gas as the backup fuel and supplementary fuel, both pure hydrogen combustion and multi-fuel blended synergistic combustion can be achieved;

[0022] S4. Determine electricity by hydrogen. According to the consumption of hydrogen, the main fuel of the pan-hydrogen gas turbine, calculate the amount of electricity required for hydrogen production by electrolysis of water. The amount of electricity required for hydrogen production is preferentially supplemented by surplus electricity or abandoned electricity from renewable energy green electricity, and the shortfall is supplemented by valley electricity from the park power grid;

[0023] S5. Design of installed capacity of renewable energy green electricity. Determine the installed capacity of green electricity according to the total power load demand in steps S1 and S4. Through the multi-energy complementary energy system based on the pan-hydrogen gas turbine, realize "self-generation and self-use, peak shaving and valley filling, local consumption, surplus electricity to produce hydrogen, hydrogen storage for power generation, and combined heat and cooling and power generation", to ensure the complete consumption of renewable energy green electricity and the comprehensive utilization of various energy sources.

[0024] Preferably, in step S3, the fuel consumption of the pan-hydrogen gas turbine can be calculated according to the effective power generation of the pan-hydrogen gas turbine, and the specific formula is: total fuel consumption = effective power generation / power generation efficiency / (hydrogen combustion calorific value*volume fraction of hydrogen+high calorific value combustible waste gas combustion calorific value*volume fraction of high calorific value combustible waste gas+natural gas combustion calorific value*volume fraction of natural gas); further, the consumption of main fuel hydrogen = total fuel consumption*volume fraction of hydrogen.

[0025] Preferably, in step S4, the amount of electricity required for producing hydrogen by electrolyzing water is calculated based on the consumption of hydrogen, the main fuel of the pan-hydrogen gas turbine. The specific formula is: amount of electricity required for hydrogen production = amount of hydrogen consumed * unit hydrogen power consumption.

The valley electricity of the park power grid 100 is used to supply power to the electrochemical energy storage module 300 and the electrolysis water hydrogen production module 400, so as to achieve peak shaving and valley filling and peak-valley arbitrage;

[0039] It can be seen that by achieving peak shaving and valley filling, improving energy utilization efficiency, promoting the use of renewable energy and enhancing energy supply reliability, efficient, reliable and environmentally friendly energy solutions are provided for enterprises and users in the park.

[0040] The renewable energy green electricity module 200 generates electricity through wind energy, hydropower, solar energy, geothermal energy, and biomass energy, and is used to directly supply power to the user power load module or indirectly store and supply power to the enterprise-specific power grid. The surplus power or abandoned power of the renewable energy green electricity module 200 is used to supply power to the electrochemical energy storage module 300 and the water electrolysis hydrogen production module 400, so as to reduce the power cost of the water electrolysis hydrogen production module 400;

[0041] It can be seen that the renewable energy green electricity module 200 plays a multiple role in the multi-energy complementary energy system, including reducing electricity costs, improving energy utilization efficiency, promoting renewable energy consumption, enhancing energy system reliability and promoting green development.

[0042] The electrochemical energy storage module 300 is connected to the park power grid 100 and the renewable energy green power module 200 respectively. The electrochemical energy storage module 300 can use the surplus power or abandoned power of renewable energy, or the valley power of the park power grid 100 for charging and energy storage. The electrochemical energy storage module 300 discharges energy to the user power load module during peak or peak hours;

[0043] It can be seen that the electrochemical energy storage module 300 system plays a multiple role in the multi-energy complementary energy system, including saving electricity costs, improving energy utilization efficiency, enhancing energy system reliability, promoting renewable energy consumption and reducing grid pressure.

[0044] The water electrolysis hydrogen production module 400 is connected to the park power grid 100 and the renewable energy green electricity module 200, and is used to convert the system's electrical energy into hydrogen energy for storage. The hydrogen produced by the water electrolysis hydrogen production module 400 is stored in the high-pressure hydrogen storage module 401, and the oxygen produced by the water electrolysis hydrogen production module 400 is supplied to industrial oxygen users;

[0045] It can be seen that the water electrolysis hydrogen production module 400 plays a multiple role in the multi-energy complementary energy system, including hydrogen energy storage and utilization, improvement of electricity conversion efficiency, effective utilization of renewable energy, application of high-pressure hydrogen storage technology, industrial application of oxygen, and promotion of energy structure transformation.

[0046] The pan-hydrogen gas turbine combined cooling, heating and power module 500 uses the hydrogen of the high-pressure hydrogen storage module 401, the high calorific value combustible waste gas 501 and the natural gas 502 as fuels, respectively, to supply power to the user power load module while providing the user low-pressure steam load, the user medium-pressure steam load, the user hot water load and the user cooling load;

[0047] It can be seen that the pan-hydrogen gas turbine trigeneration module 500 has multiple effects such as efficient energy utilization, environmental protection and emission reduction, flexibility and reliability, economic benefits and energy security.

[0048] Furthermore, the pan-hydrogen gas turbine cooling, heating and power trigeneration module 500 includes a pan-hydrogen gas turbine 503, a waste heat boiler 504, a steam drum and a sub-cylinder 505, a steam turbine generator set 506, a hot water heat exchanger 507, an absorption chiller 508 and an exhaust pipe 509. The exhaust gas of the pan-hydrogen gas turbine 503 enters the waste heat boiler 504 to recover the waste heat and then is discharged through the exhaust pipe 509. The steam generated by the waste heat boiler 504 can directly provide the user with medium-pressure steam load through the steam drum and the sub-cylinder 505. The steam of the steam drum and the sub-cylinder 505 can directly provide the user with medium-pressure steam load. The steam can also be used to generate electricity through the steam turbine generator set 506 to provide the user with power load and low-pressure steam load at the same time. The steam from the drum and the sub-cylinder 505 can also be used to provide the user with hot water load through the hot water heat exchanger 507. The steam from the drum and the sub-cylinder 505 can also be used to provide the user with cooling load through the absorption chiller 508. The raw materials of the pan-hydrogen gas turbine 503 mainly use hydrogen from the high-pressure hydrogen storage 401 and high calorific value combustible waste gas 501. The natural gas 502 serves as a backup fuel and supplementary fuel to play the role of an emergency backup gas source.

[0049] It can be seen that the pan-hydrogen gas turbine trigeneration module 500 integrates multiple components such as the pan-hydrogen gas turbine 503, the waste heat boiler 504, the steam drum and the sub-cylinder 505, the steam turbine generator set 506, the hot water heat exchanger 507, the absorption chiller 508 and the exhaust pipe 509, forming an efficient, environmentally friendly and multifunctional energy supply system. The system uses the hydrogen of the high-pressure hydrogen storage module 401 and the high calorific value combustible waste gas 501 as the main fuel, and natural gas 502 as the backup fuel and supplementary fuel, providing users with multiple energy loads such as electricity, medium-pressure steam, low-pressure steam, hot water and cooling.

[0050] The embodiment of the present invention also provides a design method for a multi-fuel pan-hydrogen gas turbine multi-energy complementary energy system, which specifically includes the following steps:

[0051] S1. Obtain the energy load demand of enterprise users in the park, including power load, low-pressure steam load, medium-pressure steam load, hot water load and cooling load, conduct a comprehensive analysis of the energy load, predict the maximum value, normal value and minimum value corresponding to different energy loads based on the analysis results, and determine the design value of the relevant loads;

[0052] S2. Determine electricity by heat. Based on the principle of energy conservation, the design values ​​corresponding to the low-pressure steam load, medium-pressure steam load, hot water load, and cooling load are uniformly converted into the recoverable heat load of the flue gas discharged by the pan-hydrogen gas turbine 503. According to the converted value of the heat load, the installed power and model of the pan-hydrogen gas turbine 503 are selected, and the effective power generation of the pan-hydrogen gas turbine 503 can be further determined;

[0053] S3. Based on the effective power generation of the pan-hydrogen gas turbine 503, the fuel consumption of the pan-hydrogen gas turbine 503 can be calculated. With hydrogen and high calorific value combustible waste gas 501 as the main fuels and natural gas 502 as the backup fuel and supplementary fuel, both pure hydrogen combustion and multi-fuel blended synergistic combustion can be achieved. The calculation formula is: total fuel consumption = effective power generation / power generation efficiency / (hydrogen combustion calorific value * hydrogen volume fraction + high calorific value combustible waste gas (501) combustion calorific value * high calorific value combustible waste gas volume fraction + natural gas (502) combustion calorific value * natural gas volume fraction); further, the main fuel hydrogen consumption = total fuel consumption * hydrogen volume fraction;

[0054] S4. Determine electricity by hydrogen. According to the consumption of hydrogen, the main fuel of the pan-hydrogen gas turbine 503, calculate the electricity required for the electrolysis of water to produce hydrogen 400. The electricity required for hydrogen production is preferentially obtained by using the surplus electricity or abandoned electricity of the renewable energy green electricity 200. The shortfall is supplemented by the valley electricity of the park power grid 100. The calculation formula is: electricity required for hydrogen production = hydrogen consumption * unit hydrogen power consumption;

[0055] S5. Design of installed capacity of renewable energy green electricity 200. Determine the installed capacity of green electricity according to the total power load demand in steps S1 and S4. Through the multi-energy complementary energy system based on the pan-hydrogen gas turbine 503, realize "self-generation and self-use, peak shaving and valley filling, local consumption, surplus electricity to produce hydrogen, hydrogen storage and power generation, and trigeneration of cooling, heating and power", to ensure the complete consumption of renewable energy green electricity 200 and the comprehensive utilization of various energy sources.

[0056] In summary, the present invention controls the average electricity price of hydrogen production to no more than 0.2 yuan / kWh by producing hydrogen from abandoned electricity and supplementing the gap with valley electricity. The proportion of electricity consumption cost of hydrogen production is reduced from 61% to 44%, which reduces the cost of hydrogen production and improves the economic benefits of hydrogen combustion engines.

[0057] At the same time, the installed power and performance comparison of hydrogen fuel cells (10W~1MW), hydrogen internal combustion engines (100kW~10MW) and hydrogen gas turbines (100kW~1000MW) were analyzed. As a large-scale green hydrogen consumption method, for application scenarios with steam demand, hydrogen gas turbines have obvious advantages over fuel cells and hydrogen internal combustion engines.
