Embodiment
The object of various embodiments of the present invention is to provide a kind of electric energy generating method and electric energy generating system, and for utilizing the process of green energy resource generating, storage is from random and be difficult to the energy of controlled green energy resource.Below describe the preferred forms of the present invention that inventor thinks, those skilled in the art will be by the following drawings and embodiment, clearer understanding feature of the present invention and beneficial effect.Yet, along with the variation of time, can the present invention be modified and be changed, the preferred forms that inventor thinks also can change thereupon.Therefore, this description aims to provide example, and unrestricted.
The limitation of green energy resource output energy is that its maximum is limited to the specific time period.For example, for wind energy, in locality, only at special time period, just there is so large wind-force; For solar energy, in locality, only at special time period, just there is so many photon.Therefore, although the energy that green energy resource is exported also exists certain cycle to change, but the variation of the cycle of this exported energy might not be synchronizeed with electrical energy demands, in fact the overwhelming majority is all asynchronous, that is to say, the energy output of these green energy resources and the difference between electrical energy demands are also changing over time, thus the excess energy cycle while forming institute's electric energy of export over electrical energy demands, and electrical energy demands over the loss energy cycle while exporting electric energy.
With reference to figure 1, ground thermoelectric power 101 times to time change, yet the output valve 102 of underground heat is essentially steady state value, and cannot adjust with the energy requirement of extra variation, thereby produce by the excess energy cycle 110 of shadow representation and the loss energy cycle 120 being represented by cross-hatched.Perhaps someone can build the geothermal power plant with vast capacity, and to deal with the peak period of electrical energy demands, still, this is also infeasible or do not possess cost benefit technically.
With reference to figure 2, also there is similar situation in wind energy.Although wind-driven generator is set in the position with metastable wind as much as possible, but weather condition might not coordinate, and because wind among one day also can change, make output valve 201 temporal evolutions of wind-driven generator also there is maximum output valve and minimum output valve.In addition, output valve 210 might not match with demand 202, thereby has produced by the excess energy cycle 210 of shadow representation and the loss energy cycle 220 being represented by cross-hatched.
By adopting the stand-by power source mainly being driven by fossil fuel to deal with output randomness random and that be difficult to the controlled electric energy energy, it is a kind of compensation scheme.Wherein, when those are random and be difficult to electric energy disappearance that controlled green energy resource exports, start stand-by power supply; When those are random and be difficult to electric energy that controlled green energy resource exports while recovering, suspend stand-by power supply.Yet, this mode possible in theory, but that practical operation is got up is quite expensive, and can cause the more loss fast of main intensive equipment, and this also can with the initial hope of using " green " energy, eliminate carbon emission, run in the opposite direction.
At electrical energy demands low-valley interval, by random and be difficult to the electric energy that controlled green energy resource produces and can be wasted because there is no consumer objects, and cannot replace by the electric energy producing such as more " dirty " energy such as fossil fuels.This makes green energy resource when replacing other and have the energy of a large amount of carbon contents, on capacity usage ratio, is restricted, thus the most not desirable on economy or environment.
Be subject to the restriction of himself characteristic, random and to be difficult to the capacity usage ratio of controlled green energy resource also very low.Give an example, according to the part energy sector (DOE) of energy information administrative office (EIA), all wind-force in 2009 is 34296 megawatts (MW), amount to 73886132 kilowatt hours, its capacity usage ratio (once institute's electric energy that produces and the ratio that operates the electric energy that can produce are 24/7) is 24.6%.So low capacity usage ratio not only reflects that air-out is not the such fact always having to a certain extent, to a certain extent also by being wasted and causing at electrical energy demands low-valley interval electric energy.
Fig. 3 is in certain 24 hours period in April, 2008, the schematic diagram of wind energy 301 and electrical energy demands 302, and Fig. 4 is in certain 24 hours period in July, 2008, the schematic diagram of wind-powered electricity generation 401 and electrical energy demands 402.In Fig. 5, with solid line, represent the average wind energy output of a period of time in July, and with dash line, represented the average load of corresponding New York.Fig. 6 is composite columnar section, wherein with column form, represents the capacity usage ratio of wind, and the demand that represents New York with striped.These data are all expressed, and wind energy is periodic cycle, not like this within just for one day, and are also like this with the mean value of 1 year.And wind energy is not corresponding with the requirements of electric energy, for example, be the demand peak phase summer, and at this moment wind energy output is but minimum.
With reference to figure 7, along with the variation of time, the output valve 701 of Texas wind energy project and the difference between load 702 are also changing, and have formed excess energy cycle and loss energy cycle.Can see that the difference of output valve 701 and load 702 is quite large in load top period.
Above-mentioned by random and be difficult to energy that controlled green energy resource produces and the difference between electrical energy demands in order to overcome, thereby more effectively these green energy resources are applied to there is the mode of benefit, each embodiment of electric energy generating method of the present invention and electric energy generating system is by the excess energy in described excess energy cycle IT green energy resource institute output, and be stored in more senior fossil fuel for using when the described loss energy cycle, thereby meet electrical energy demands extra when described loss energy cycle.
