Abstract

This invention integrates the fuel cell, solar photovoltaic, and wind energy to construct a hybrid clean-energy power-supply framework. In recent, the mentioned green-energy power plants have been utilized individually for various power-supply systems. However, there is no integrated mechanism including these three generating systems due to the reasons of different system characteristics, complex interface and expensive generating cost. In this invention, the maximum-power-point-tracking methodology is adopted to raise the output power of the free-cost solar photovoltaic and wind energy for providing power loads. Moreover, the extra energy is transferred to electrolytic equipment for producing the oxygen and hydrogen gases into the fuel cell generating system. In order to inhibit the peak-power utilization demand and reduce the overload extra fee, the utility power at off-peak period can be used to electrolyze water into oxygen and hydrogen gases for providing the fuel of the fuel cell generating system. In addition, it also can be taken as an air environmental-protection battery for providing the backup power source under the utility power failure. Furthermore, a centre microprocessor is utilized to monitor and control the power flow to ensure the stable power supply and to reduce the generating cost. In this framework, it also has the selective modules of stand-alone or grid-connection system with the mechanism for avoiding the islanding problem.

Description

F1 \ 22 Description of the invention: [Technical field to which the invention belongs] Humanism, Ming Nai uses fuel cells, solar photovoltaic, and wind energy to become a mixed δ-type clean energy power supply architecture. Fuel cell utilization = reactants are hydrogen and oxygen, the only products produced are pure water, DC = and waste ',,, and two kinds of products are all available resources and the entire process will not produce any of them. Environmentally friendly power generation device. Solar cells use the photovoltaic effect to convert light energy into electricity. Practical solar cells all use light guides: silicon is the main raw material. Solar photovoltaic energy is a clean, pollution-free and available energy source, and it is inexhaustible. It is inexhaustible, so it is also one: a guaranteed & electric device. Wind energy uses the electromagnetic principle to drive the fan blades of the vertical structure through the wind, which in turn drives the rotor of the wind generator, so the power source is available. This is a clean, pollution-free, and effort-free, environmentally friendly energy source for natural energy supplied to Zhituo. . In order to cooperate with the power control and power regulation, all calculations are performed by the central processing unit of the power monitoring system, and then each generator is controlled to step up to the DC bus, so as to feed into the AC mains and supply power to the load through the energy conversion system. . [Previous technology] The rise of the awareness of nuclear security in recent years and the problem of pollution caused by the dioxide caused by the greenhouse effect 'make the application of renewable energy again an attractive, simple and simple concept of sustainable development It is also the main driving force for clean energy. _Batteries generate electricity by electrochemical reactions, and there is no need to react with oxygen. 'The flow of electrons generates electricity, water and heat = no pollution. The function of a fuel cell is similar to that of a battery ’, but it is different from a battery in that as long as it has sufficient fuel, it will not run out of electricity and does not need to be charged. As long as there is fuel, it can generate electricity. It is an energy conversion device, so no traditional battery is limited by the cycle charging life and environmental protection issues after disposal. If the fuel cell has a converter that can convert natural gas or other fuels into hydrogen, then these fuels can also be applied to fuel cells. For this reason, the present invention is equipped with an electrolytic system to directly obtain hydrogen and oxygen from water, so there is no need to use natural gas, etc. The fuel obtains hydrogen and is completely self-sufficient, which is consistent with the purpose of clean energy. Solar energy is the largest energy source of the solar system. With the improvement of the conversion efficiency of solar cells and the rapid progress of the semiconductor industry in recent years, the cost has continued to decrease, and the days of economical and practical use of solar energy are getting closer. Because Taiwan is located in the subtropics and has sufficient light sources, it is very suitable for the development of solar energy. Stable illumination can provide stable output power, and simple equipment maintenance, will become the mainstream of power generation in the future. Wind power is a kind of renewable energy with less pollution. Some countries with rich wind resources have begun to develop in large quantities. Especially because it is green power, it is increasingly supported by people. In recent years, the installed capacity has increased sharply. Contributions cannot be ignored. At present, the cost of the above-mentioned power generation equipment is still very high. Due to the rising awareness of environmental protection, coupled with the continuous promotion and funding of installations in countries around the world, and the continuous research and development, the cost reduction has been accelerated. According to the report, the cost of wind power generation has been lower than 2 yuan per kilowatt-hour. As for the cost of fuel cell and solar power generation, it is still much higher than the market price of electricity. However, as the market demand grows, the future manufacturing technology will continue to improve and the results of mass production will be expected. price. Looking to the future, the cost of power generation will be calculated in a balanced manner, fuel, and maintenance costs. Based on this concept, the present invention integrates and integrates the hybrid clean-month B-source power generation and power supply S to facilitate the practical application. The output voltage and output current of the two power generation systems show a non-linear relationship. Objective: The independent power generation system has been developed to feed the mains power, but no simultaneous examination has been made. Both of them use the mechanism to feed the mains power and use cost-oriented development strategies. The weekly rule 'controls the amount of power generated by the three, and at the same time it is stable and urgent. [Abstract] People, the invention is to use fuel cells, solar photovoltaic and wind energy to become a mixed type 5 clean energy power supply architecture. Fuel cell electrochemical reaction principle, i reactants are hydrogen and oxygen, the only products are pure water, DC current and waste ..., one = two products are available resources and the whole process will not produce, a mouthful This is an environmentally friendly power generation device. Solar cells use the photovoltaic effect to convert light energy into electricity. Practical solar cells use photoconductive materials as the main raw material. Solar photovoltaic energy is clean, pollution-free, and ::::: energy, and it is inexhaustible. Exhaustion, so it is also-surname Γ ,, "Electric device. Wind energy uses the electromagnetic principle to propel the fan blades with special structure through the wind to drive the rotor of the wind generator. Therefore, the power is used. This is clean and pollution-free and does not require laborious mining. — The power control of the system, the power of the above three types of power generation equipment is calculated by the central processor of (power = control system), and the power is dispatched to control each power =

The system is boosted to a DC bus to feed AC mains through the energy conversion system and supply power to the load. / ;, L The principles and comparative effects of the present invention to improve the prior art are as follows: 1. Utilizing the city electricity at night off-peak (two-stage meter setting from 10.30 to 7 in the evening to 7 in the morning) preferential electricity price 'electrolyzed water into radon gas And oxygen storage. ^ The peak (out-of-peak time) electricity costs are more than μ times higher than the off-peak electricity costs, so starting fuel cell power generation during the day, in addition to reducing mobile electricity costs (total electricity consumption times multiplied by the cost per kilowatt-hour) is more important to suppress the spikes Use of electric power, reducing super-charges per kilowatt. In addition, the stored hydrogen can be used as a gas-friendly animal battery to provide emergency power supply at night when power is interrupted. Excess oxygen can be sold in medical or oxygen welding places. -2.1 The central processor monitors and dispatches each power generation and power supply system. The precise calculation system combines X and the best power generation mode to ensure power supply reliability and power costs. One 3. The power generation system can choose parallel or independent power supply system, with a mechanism to prevent island effect. When the mains power is normal, select the mains power supply in parallel. Once the mains power is interrupted, the mains power will be isolated and the load will be dispatched to continue to supply power to some circuits. = Fuel cells replace batteries and are said to continue to supply power. Solar cells, wind power = the power generated by the motor, which is easily affected by the environment, time and climate. For example, if the sun = the amount of illumination is closer to the equator, the illumination is higher, the summer season is higher than the winter season, and the illumination time is longer, but power generation is stopped at night. Wind power generators are installed in: the sea area or the northeast monsoon in the winter of northern Taiwan, there are more electricity generation time than the daylight, but the amount of wind is not as stable as the sunlight, and time is easy to handle. To sum up, the solar cell and wind power generation, and the motor capacity of the conversion motor are partially complementary to each other. The power generation of the two in different time periods and regions has a tendency to balance. In any case, the power supply cannot be maintained at night or on or before the day. In general, the solution for independent power supply systems is to add batteries and continue to provide power. Under two hundred percent depth, the average life of a lead-acid battery can be used about 300 times, so it only counts… and the cost of sales ′ is several times the commercial power. In addition, there are still environmental issues such as large size, load capacity, low storage capacity, and scrap. Therefore, although the above two types of power generation systems do not require fuel costs, once the battery is used, the purpose and consistency of cleaning the moonlight source will be difficult to achieve. Combining fuel cell and electrolyzed water mechanism: It can effectively solve the current problem of continuous and independent power supply of solar cells and wind turbines. As long as the supply of hydrogen is not scarce, the power generation system will be uninterrupted, based on the solar cells and wind turbines detected at any time. In the power supply, the fuel cell power generation system is used to adjust the insufficient power generation volume, and the entire private and traditional diesel generators have no air pollution, taking into account the characteristics of environmental protection and cost reduction. [Embodiment] As shown in FIG. 1, a block diagram of a hybrid clean energy power supply architecture disclosed in the present invention is provided. The power supply system includes an interface for feeding mains power. The transformer of the self-set distribution station set by general high-voltage users is stepped down to a low-voltage feeder line 101, which is configured via a distribution board 102 and routed to various places. The components included in the switchboard 1G2, such as the wire-recording switch, protect the wires of the m circuit to prevent the wire from igniting. Electricity off: Control the coil of the electromagnetic switch to start and break the load of its own branch. The control signal is provided by the central processing unit. Digital switch touch; voltage ratio (PT) and current ratio (CT): send the voltage and current of the shunt to the central processing H operation. The power distribution # 1G2 has the function of positively replacing Ii # # V2 π | to protect the shunt line and isolate the mains from the power load 103. Therefore, the hybrid clean energy power supply architecture of the present invention can feed power from the power distribution panel 102. The detection signals of the specific current and voltage regulators placed on the plate serve as the basis for power control. At the same time, the electromagnetic switch is controlled to start and stop the load circuit to achieve load control, and isolate the mains circuit to avoid island effects and prevent mains power failure. Hybrid clean energy power supply system collapsed due to overload. The electricity load 1G3 $ means the internal electricity consumption of the user of the device's hybrid clean energy power supply system, which is the calculation target of the electricity consumption of the present invention. Electricity for hybrid clean energy comes from hydrogen, solar and wind. Hydrogen energy is composed of an electrolytic system 104, an oxygen storage system 105, a hydrogen storage system 106, and a fuel cell power generation system 107. The electrolysis system 104 sends the water electrolysis gas and oxygen to the oxygen storage system 105 and the hydrogen storage system 106 respectively. The required power comes from the excess power generated by clean energy and low-priced electricity from off-peaks at night. The hydrogen in the hydrogen storage system 106 is the main fuel of the fuel cell. The catalyst materials such as platinum, silver, and lithium are used to separate the electrons in the hydrogen and lead out the load end to form an electric current generation system. The oxygen in the oxygen storage system and system 1 () 5 is the combustion-supporting gas necessary for the 'chemical reaction' in the fuel cell power generation system jG7. Its demand ratio is smaller than that of the hydrogen 'power generation process towel, which can store and sell excess oxygen and indirectly reduce the cost of power generation; The solar photovoltaic power generation system 108 and the wind power generation system 109 provide the power required to feed the negative t 103 in the mains power supply. If there is surplus power, all of the power supply system is provided. Output ㈣ to-DC level is transmitted to DC bus, and then the energy conversion system 11G is introduced. The system transmits the DC voltage through the full-bridge reverse-flow architecture, and the switching mechanism is adjusted by pulse width to output the sine power of the mains frequency. ， 1225m --- page change \ 93 · '22 ___gj t Inductor current modulation, batch factor ㈣ Electricity supervision _ == Electricity monitoring and protection and electric power economic dispatching two parts: Γ = each: Chengzhi =, electricity f Sensing analog signals are converted into digital signals for monitoring: no data, same-day inch protection system works normally. ",, the current signal is sent to the central processing unit I ,,,,,, and the voltage of the source, and the difference is different, and the current command is sent to each lightning system and the energy conversion system to track the flow of the power flow. . Θ The hybrid material energy power supply architecture process disclosed in the invention reveals that the amount of electricity generated is proportional to the amount of light, and the k supply and burner costs are all extracted with the maximum power on the circuit control to derive high power tracking control Mechanism, the solar cell output DC electric current and output J current have a non-linear inverse relationship between 'power in DC system, equal to electricity, the product of current' is the reason, the maximum power is to find the highest value of the product, in the process of tracking power In the 'product of solar battery voltage and desired = current must be detected at any time', the central processor must calculate a large amount of online data, and what if f ?, and if the control is unstable, it will increase the power consumption of the mechanism and achieve the maximum power control purpose. Fortunately, several methods have been proposed one after the other: effective implementation of maximum power chase control, including ㈣ feedback method, power feedback method, disturbance, and Observation method, incremental conductivity method, linear approximation method, actual measurement method, etc. The wind power generator of a wind power system can be a DC ^ motor or an alternator with a rectifier device. The output power is three times faster than proportional = It is proportional to the square of the voltage, "When the current drawn is cut, the speed will decrease." It is also the same as the solar cell is facing the problem of maximum power tracking control, so it can be solved by referring to the above method. 12 fjL ·: 1. Replace page v_ 济 调Figure II: 7: It is the processing power balance and ㈣ ^ After Tian Fancheng took high power tracking control, the solar photovoltaic power generation system 108 output power ^ 'Wind power generation system, system 109 output power is 4, the sum of the two represents t Fuel cost power generation, so in addition to fully feeding the city power, the right is greater than the load power 103 power A, then the excess power 4 is started, and the electrolysis is started. As for the second power, why not feed the power into the city power against the trend, I have two. " The reason is that, firstly, the electricity industry law has not been revised to feed the city's electricity against the tide, and there is no legal source for the power company to pay. Secondly, Taipower has set a surcharge standard for excess surcharges. Is 2-3 times the basic tariff, in other words, 15 per kilowatt "in the contract exceeds the capacity of electricity, an additional payment of up to hundreds of dollars of super about 6 surcharge, the flow of electricity paid by the same time a difference of more than a thousand times. For this reason, fuel cell power generation systems will suppress peak power consumption to avoid over-subscriptions and reduce contract capacity in response to the high electricity costs of over-subscription surcharges. This part saves costs, which is no less than reducing the electricity cost of mobile electricity. In addition, the more hydrogen and oxygen are stored, the wider the peak power suppression can be. In addition, the cost of off-peak electricity consumption at night is 40% of the peak electricity consumption. During the cough period, electricity is applied to electrolyzed water. The hydrogen produced during the day is supplied to the Z-cell battery power generation system and system 107 for power supply. During peak power consumption periods, when the p-force rate of Taipower's low-voltage feeder, line 1G1's mains power is greater than the contract capacity, fuel; the pool power generation system 107 starts, and its power generation needs to be calculated by the central processor of the power monitoring system The historical operating data of the electric load 103 is used to estimate the future over-subscription amount and the length of the over-subscription period. The hydrogen inventory is reviewed to obtain the optimal economic dispatch power generation amount. Doing such a fine calculation mainly achieves no problem. When the peak power consumption can be suppressed below the contract capacity. Otherwise 2 13

It is not necessarily enough. I want to suppress the capacity evenly, but within one month, as long as there is one time, the average power consumption in 15 minutes exceeds the contract capacity. Previous efforts to curb peak power use were in vain. However, considering the capacity of the fuel cell system 107 and the storage capacity of the hydrogen storage system 106, the contract capacity should be kept below the contractual capacity. For this reason, the next best thing is to seek the peak power consumption f ', although the peak power consumption still exceeds the contract capacity

It must be released by power generation. If the air conditioner is disabled in winter or the power consumption is low on holidays, there is no overbooking problem. During peak pricing periods, the fuel-electric power generation system 107 will be used at the maximum power generation (m ^^) until the radon is consumed to safety. The oxygen storage system can sell excess gas at any time to increase additional revenue. In general, the hydrogen required for the fuel cell power generation system 107 comes from cheap electricity at night, which is used to generate electricity during the day to reduce peak electricity costs and over-addition. It is still profitable after deducting the chemical cycle reaction loss. Figure 3 shows an embodiment of the hybrid clean energy power supply architecture disclosed in the present invention, Figure 3 (a) a fuel cell power generation system, and Figure 3 (b) a solar photovoltaic power generation system and Fig. 3 (c) Wind power generation system. As the location of the power generation system cannot be accommodated by the switchboard 102, solar cells are installed on the roof, and most of the wind power generators are installed outside the house. Furthermore, the present invention combines three clean energy sources, which inevitably requires longer power transmission lines. In order to reduce transmission losses, a stable DC voltage must be raised nearest the power generation system. DC voltage transmission lines are superior to AC transmission systems For example, there are no set 2 effects, no electromagnetic interference, less wheel power loss, no inductance to limit the maximum transmission power, etc. In addition, European and American countries have gradually reached a consensus to formulate high-voltage DC bus voltage specifications in response to the problem of renewable energy wheel power. Fuel cell 14

DC boost converter circuit 303, DC boost converter of solar cell 304

The converter circuit 306 and the DC boost converter circuit 309 of the wind turbine 307. The converters of the three power generation systems all adjust the inductor current to achieve the purpose of power control. This is because of the power generation system measured by the voltage sensor. The output DC voltage is known data, multiplied by the average output current (inductor current) of the power generation system to be controlled, which is the output power of the power generation system. The circuit structure adopts a step-up converter, so that the duty cycle (Duty Cycle) of the pulse width modulation switching is Z), the input voltage of the converter is ~, and the output voltage is Fzx; then the voltage gain ^ is

The power tracking, flow control and driving circuit 302 of the fuel cell, the maximum power tracking control and driving circuit 305 of the solar cell, and the maximum power tracking control and driving circuit 308 of the wind turbine determine the switching of the inverters of the three power generation systems, respectively. Duty cycle D. Solar energy and wind energy must draw the maximum power, so the maximum power tracking control rule must be established before the central processing unit, and the switching responsibility period D command is obtained by calculating the output voltage sensing signal of the DC power generation device. The solar cell's maximum power tracking control and driving circuit 305 also includes a sun-chasing mechanism that controls the solar panel perpendicular to the angle of the sunlight to obtain the maximum amount of sunlight. This part can be completed by using a motor lifting system in conjunction with a digital light meter. The maximum power tracking control and driving circuit 308 of the wind turbine, and another windward mechanism, controls the blade angle and the excitation voltage to absorb the highest mechanical energy. As for fuel cells, factors such as peak power consumption and higher power generation costs must be considered. Switching the duty cycle is a command that is adjusted with changes in power consumption and power generation. Regarding the control of the DC bus to maintain a fixed value, it is provided by page 15 1225

B ~~ — 丨 丨, a T _, adjust the amount of power into the mains, in other words, when the DC voltage is maintained at a set value, it means that the fed mains power is equal to the power generated by the three clean energy sources. When the central processing unit receives the signal of mains interruption, phase loss or low voltage, it immediately cuts off the mains circuit of the isolated switchboard 102 and calculates the output power of the three generation systems. Then, according to the emergency priority of power supply in the switchboard 102, The load circuit is selected in parallel to adjust the output power 4 'of the fuel cell power generation system as a balance mechanism between power generation and power consumption. FIG. 4 shows an energy conversion system 110 of an embodiment of a hybrid clean energy power supply architecture disclosed in the present invention. 401 is the calculation of the power input to the city power, which is one of the functions of the power monitoring system 111. It includes the output power of all power generation systems and the power of each loop of the city power to calculate the net output power of the power generation system. Control drive circuit technology, positive performance = can convert the DC command that feeds the city power into an AC synchronous current command, control the four switch drive signals of the inverter circuit 403, forcing the inductor current tracking of the skin circuit 404 Regardless of the AC synchronous current command. If the DC dust of the DC generator set is maintained at the set value, it means that power generation and power supply are maintained in balance. On the contrary, if the electricity M of the Anzhi bus is too high, it means that the power generation is higher than the second rate of the fed mains, and the feed current should be increased. When fed with the sine current of the city power and the city power ^ ♦ ♦ will the power board be able to reach the power factor of the sheep, so that the hybrid / power source of the invention can be cleaned from the power supply structure of the bus, thunder, and ancient electricity, then the power of the machine is reduced / the claw is small , Improve the voltage waveform, and then return to the overall efficiency of the source conversion system 110. For example, the implementation of a hybrid clean energy power supply architecture that was not disclosed by Lei Ding, Benming Ming, etc. The electrolyzed water of young money becomes a device of hydrogen and oxygen. -Generally, water is extremely difficult to electrolyze. Usually water is added with sodium oxychloride or sulfuric acid 505. 16

Electricity, and then use a carbon rod or injection needle as an electrode. The positive carbon rod 501 is connected to the positive voltage of the DC voltage bus 506; the negative carbon rod 502 is connected to the negative voltage of the DC voltage bus 506. Direct current is applied to the electrodes, and 0 / T ions move to the positive electrode of the DC voltage bus 506 in the water. Oxygen can be collected at the positive oxygen collection container inlet 503 and sent to the oxygen storage system 105. While // + is moved to the negative electrode, hydrogen gas can be collected at the inlet 504 of the hydrogen collecting container of the negative electrode, and is transported to the storage system 106 by the delivery device. During electrolysis ’, the more the south of the DC voltage bus 5 06 or the closer the poles of the poles are, the faster the rate of bubble generation during electrolysis. Since the density of generated hydrogen and oxygen is smaller than that of water, and it is insoluble in water, the method of using this property to collect gas is called drainage gas collection method.
