Description

Civilian direct current system and direct current supply method

Technical field

The present invention relates to direct current multiplexe electric technology field, particularly relate to civilian direct current system and the direct current supply method of regenerative resources such as effectively utilizing solar energy, wind energy, fuel cell and trough civil power.

Background technology

The energy and environmental problem have become the great difficult problem of the world today and mankind's facing, and the utilization of the regenerative resource that taps a new source of energy, strengthens and utilization ratio etc. also become the focus that various countries pay close attention to day by day.To apply efficient, the economic novel electric power technology of new and renewable sources of energy, such as solar power generation, wind power generation, miniature gas turbine generating, fuel cell power generation and bioelectrogenesis etc., power nearby in load place, to meet the needs of specific user, the advantage such as have that using energy source is high, good energy-conserving effect, pollution are few.

The DC generation facility of fuel cell, solar cell and wind power generation etc. provides direct current, and the power utilization environment due to us is alternating current, so, usually need converting direct-current power into alternating-current power.First, alternating current has the requirement of amplitude, frequency, phase place, needs extra cost to realize synchronously grid-connected.Secondly, when power consumption equipment needs direct current, need first by the converting direct-current power into alternating-current power of DC generation facility output, and then convert direct current to from alternating current, in the electronic conversion process of such two-stage, the power loss that electric power conversion causes increases, and the utilization ratio of electric power declines, mutual conversion in addition owing to needing conversion equipment to carry out alternating current-direct current, therefore also needs more cost.

On the other hand, along with the development of household electrical appliance, the power inside of household electrical appliances also direct current increasingly, such as universal gradually LED illumination light source major part is with direct current supply work, Household audio video and the information communication equipment such as present TV, computer, sound equipment, charger for mobile phone are all finally with various direct current work; Present air-conditioning, refrigerator, washing machine, electric fan, dishwasher and water heater, although be all Alternating Current Power Supply, have data to show, along with the development of DC Frequency Conversion Technology, direct current supply work can be more efficient.Therefore, the power inside direct current of household electrical appliances also exists contradiction with the present power utilization environment that exchanges, and the electric energy that the generating equipment in various energy resources source provides is with exchanging power utilization environment also also exists loss that is grid-connected and that change and cost now.

Further, because alternating current can not directly store, so it can only use in real time.When the sufficient need for electricity of electric power supply is little or do not have then can cause waste of energy during demand, such as the late into the night, need for electricity was little, and a large amount of electric power is wasted; When do not have electric power supply or electric power undersupply but have need for electricity or need for electricity large time then cause and cannot meet need for electricity.But direct current can directly store easily, without the need to real-time use, remainder can be stored when electric power supply is greater than need for electricity, the electric energy of storage can be used when electric power undersupply.

Therefore, the direct current directly utilizing DC generation facility to produce uses for direct-flow electricity utilization apparatus, the energy consumption that the electric power conversion not only can reducing the above-mentioned two-stage produces, and can store produced direct current at any time, powers according to need for electricity.

For the utilization of the solar energy in regenerative resource, the mode being converted to electricity mainly uses solar panel.The output voltage of solar panel and power along with in one day sunshine situation difference change, under the condition at certain sunshine, if draw the output current of solar panels too much, output voltage will decline, to such an extent as to lower than outside available scope, limiting case is exactly that output current is maximum, but output voltage is zero.And this at sunshine situation, along with the time from morning to night, the latitude of the cloudy fine day of weather condition and region is equal all in change, this just makes effective utilization of solar energy create certain difficulty.The load matched that will make the output of solar energy and be added on solar panels in using electricity system, to obtain maximum power, and this coupling be along with the time and sunshine weather change and dynamic change.

Output characteristic and the solar energy of wind power generation are similar, if be added in the overload that wind power generation exports, fan blade spin down will be made, output voltage can decline, under limiting case, fan blade can stop operating, although now output current is maximum, but output voltage is almost nil, the electric energy of output is also almost nil; So for wind energy, in the design of using electricity system, also to there is dynamic load matched.

For the electric main of AC network, use greatly to improve the service efficiency of electric main when how to be electricity consumption " crest " by electric energy conversion time electricity consumption " trough " is also the problem that people constantly study always.

Fig. 9 shows the flow chart of the direct current supply method according to one embodiment of the present invention.As shown in Figure 9, direct current supply method 900 of the present invention realizes mainly through following steps:

In step S910, come configuration energy source based on the kind of energy source and the demand of performance and direct-flow electricity utilization apparatus; Gather electric energy according to predetermined scheduling controlling policy control from energy source, the electric energy of collection converted to the direct current of predetermined dimension and transmit through direct current power utilization network.

Direct current supply method of the present invention can adopt multiple kinds of energy source to power according to demand, described energy source can be such as solar power plant, wind energy generating plant, alternating-current power supply etc., often kind of energy source also can adopt one or more, to meet power supply within the specific limits.When taking multiple energy source, the performance of each energy source also may be different, and such as its electricity, generated output etc. that can gather may be different.In addition, in order to can regenerative resource be made full use of, reduce carbon emission amount, alternating current will be used as little as possible.But owing to there is again the unsteadiness that electric energy provides as the regenerative resource such as solar power generation, wind power generation, so, alternating current can be selected as alternative energy source, when the electric energy that renewable energy resource provides is not enough, AC-powered can be used, to guarantee the stability of powering.

Therefore, such as, when a community adopts direct current to be customer power supply, needing the performance of the power consumption needed for the direct-flow electricity utilization apparatus in this community, available energy source, energy source to calculate needs for this cell configuration how many energy sources.Alternatively, the energy source of the power consumption needed for its direct-flow electricity utilization apparatus can be exceeded for this cell configuration.

Then, electric energy is gathered from energy source according to predetermined scheduling controlling policy control, and the electric energy of collection is converted to the direct current of the predetermined dimension needed for direct-flow electricity utilization apparatus, through the transmission of direct current power utilization network, thus electric energy can be provided for the direct-flow electricity utilization apparatus being connected to direct current power utilization network.

In addition, in order to ensure the stability of power supply, step S920 can also be adopted.

In step S920, configure one or more first electric energy storage device based on the kind of energy source and the demand of performance and direct-flow electricity utilization apparatus; Gather electric energy be stored in described one or more first electric energy storage device according to predetermined scheduling controlling policy control from energy source, the direct current electric energy in the first electric energy storage device converted to the direct current of predetermined dimension and transmit through direct current power utilization network.

Because the direct direct current obtaining predetermined dimension from energy source collection electric energy might not be guaranteed provide sufficient direct current or may enable electric main, for this reason, can determine to configure how many first electric energy storage device according to the demand of the kind of adopted energy source and performance and direct-flow electricity utilization apparatus.Here, the first electric energy storage device gathers from energy source the equipment that electric energy carrying out stores.Like this, the power storage of renewable energy resource can be got up, also the trough civil power of electric main can be stored, for direct-flow electricity utilization apparatus is powered, reach the effect making full use of the energy.Certainly, but when the first electric energy storage device is failed to store enough direct current electric energy but needed it to store to use when a certain amount of direct current electric energy is prepared for urgent need, also the non-trough civil power of electric main can convert direct current to and be stored in the first electric energy storage device.

In addition, about described step S910 and step S920, on the one hand, wherein any one step can be adopted, that is, electric energy can be gathered then for direct-flow electricity utilization apparatus is powered from energy source, also first the power storage from energy source collection can be got up, and then power for direct-flow electricity utilization apparatus.On the other hand, step S910 and step S920 also can adopt, so both can collecting energy source electric energy and directly for direct-flow electricity utilization apparatus is powered, also the first electric energy storage device can be used to power, the stability of powering can be guaranteed better, in addition, regenerative resource and/or trough civil power can also be made full use of.

In addition, alternatively, step S930 can also be adopted, by the direct current power storage transmitted in described direct current power utilization network in the second electric energy storage device being connected to described direct current power utilization network.Like this, the direct current power storage that can will transmit in direct current power utilization network, on the one hand, enough electric energy are being obtained by step S910 and step S920, and the electric energy transmitted in direct current power utilization network is when exceeding the electricity consumption needed for direct-flow electricity utilization apparatus, the waste of electric energy can be avoided, on the other hand, this provide another kind of accumulation mode, also can as the power supply of direct-flow electricity utilization apparatus.When adopting step S910, step S920 and step S930 can adopt, and also only can adopt one of them.When not adopting S910 adopting step S920, S930 can be adopted, also can not adopt S930.

Next, in step S940, obtain the electricity related data of input and output of equipment and/or the electricity related data of the electricity related data of the input and output of the first electric energy storage device and/or the input and output of the second electric energy storage device that gather electric energy from energy source, as the first information.In step S970, based on the first information, according to predetermined scheduling controlling strategy, control to gather the input and output of equipment of electric energy and/or the input and output of the input and output of the first electric energy storage device and/or the second electric energy storage device from energy source.

By step S940, the ability of equipment collection electric energy and the ability of output electric energy that gather electric energy from energy source can be known, the power reservoir capacity of the first and second electric energy storage devices and power supply capacity, thus in step S970, according to predetermined scheduling controlling strategy, whether the equipment that can control to gather from energy source electric energy gather electric energy from energy source and whether export electric energy, and determine when there is multiple energy source which energy source to gather electric energy from, the whether electric power storage of the first and second electric energy storage devices can be controlled, store how many electric energy, whether export electric energy and export how many electric energy.Such as, when the energy gathered from solar energy source is abundant, does not then enable and gather alternating current from electric main; When providing enough electric energy for direct-flow electricity utilization apparatus with the first and/or second electric energy storage device, the equipment gathering electric energy from energy source can export electric energy; When the first and/or second electric energy storage device has stored the electric energy of rated capacity, then stop continuing as the first and/or second electric energy storage device electric power storage; When the first and/or second electric energy storage device electric power storage not made to reach rated capacity from the electric energy of regenerative resource collection, optionally can be respectively the first and/or second electric energy storage device with regenerative resource and electric main and certain charge capacity is provided; When the first and/or second electric energy storage device has enough electric power storages, can be controlled it and export electric energy or do not export electric energy, when the first and/or second electric energy storage device does not have enough electric power storages, can be controlled it and do not export electric energy.

Due at different date and times, the power supply capacity of different energy sources is different, such as, for solar energy source, can only by day and fine day can gather electric energy, then can not gather electric energy from it at night from it; For electric main, power consumption is large by day, and be then in electricity consumption trough at night, a large amount of electricity produced are wasted; In addition, also can may be different according to the difference of date and time to the control of direct-flow electricity utilization apparatus even load equipment.So, above the described first information can also comprise the date and time information that direct-flow electricity utilization apparatus is controlled, when energy source comprises AC energy source, the described first information also comprises the date and time information using AC energy source.

In addition, in order to carry out power supply control more accurately further, step S950 can also be adopted, obtain and gather the equipment of electric energy and/or the oneself state information of the first energy storage system and/or the second electric energy storage device from energy source, here, oneself state information can comprise each parts and is in the state informations such as work, standby, fault.。Like this, in described step S970 above, when controlling according to scheduling controlling strategy, based on the first information can also comprise the oneself state information of each equipment obtained in step S950.

In addition, in order to improve control precision further, step S960 can also be adopted, gather the environmental data around DC energy source because DC can in a steady stream environment around directly affect the electric energy gathered from it number, such as, when fine day, more electric energy can be gathered from solar energy source, when the cloudy day, then gather less.When wind-force is larger, wind power plant can provide more electric energy, and when wind-force is less, wind power plant then provides less electric energy.Therefore, in described step S970 above, when controlling according to scheduling controlling strategy, based on the first information can also comprise environmental data around the DC energy source that gathers in step S960.

In direct current supply method of the present invention, described predetermined scheduling controlling strategy can set as required, such as, can comprise following strategy by equipment:

Strategy 1, when the effective power of renewable energy resource (such as solar battery group) be greater than needed for current all direct-flow electricity utilization apparatus total energy power time, determine that DC adopts energy module work, gathering direct current from renewable energy resource is that direct-flow electricity utilization apparatus is powered, and AC adopts and can module not work;

Strategy 2, strategy 1 basis on, when the effective power of renewable energy resource be greater than needed for current useful energon system total can power and the two difference be greater than the first setting threshold time (now can think that renewable energy resource also has available power), be minimum the first and/or second electric energy storage device charging of one or more dump energy by renewable energy resource.At this moment the size of the main effective power according to renewable energy resource decides with charging power demand; First setting threshold can artificially set as required.

Strategy 3, when the effective power of renewable energy resource be less than needed for current all direct-flow electricity utilization apparatus total energy power time, direct-flow electricity utilization apparatus uses the accumulate of the first and/or second electric energy storage device, when all electric energy storage devices do not have accumulate, then gather alternating current from electric main and convert thereof into direct current, for described direct-flow electricity utilization apparatus is powered; If the output gross power of all electric energy storage devices is less than the total energy power needed for all direct-flow electricity utilization apparatus, then partly gathering alternating current from electric main is that described direct-flow electricity utilization apparatus is powered;

Strategy 4, strategy 3 basis on, needs from electric main gather alternating current be described direct-flow electricity utilization apparatus power time, be in the non-trough civil power period if current, according to setting in advance, close some allow closedowns direct-flow electricity utilization apparatus;

Strategy 5, strategy 3 basis on, when the effective power of renewable energy resource is greater than the second setting threshold values, with renewable energy resource be one or more dump energy minimum first and/or second electric energy storage device charging.Here the second setting threshold values can artificially set as required.

Strategy 6, needs from electric main collection alternating current be described direct-flow electricity utilization apparatus power time, the civil power trough period is in if current, and the reserve of electricity summation of all electric energy storage devices be less than all direct-flow electricity utilization apparatus in the first time period T1 (such as 3 days) of setting normal use needed for power consumption summation, be then that minimum the first and/or second electric energy storage device of one or more dump energy charges with electric main.

If the reserve of electricity summation of strategy 7 all electric energy storage devices be more than or equal to all direct-flow electricity utilization apparatus in the first time period T1 (such as 3 days) of setting normal use needed for power consumption summation but be less than the power consumption summation of all direct-flow electricity utilization apparatus in the second time period T2 (such as 5 days) of setting normally needed for use, then electric main is used to be that described direct-flow electricity utilization apparatus is powered, but do not give the first and/or second electric energy storage device charging, wherein, T2 is greater than T1.

It should be noted that, in order to ensure the realization of above-mentioned scheduling controlling strategy, must make it to adapt with the demand of direct-flow electricity utilization apparatus (power, power consumption etc.) through carefully calculating from the configuration of the energy source collection equipment of electric energy, the ability (comprising power, accumulate capacity etc.) of the first and/or second electric energy storage device.
