Description
Technical field
The present invention relates to the storage of electric energy and from fields such as net, parallel network reverse generatings, specifically refer to solar energy, electrical network electrical power storage in energy storage device (such as battery pack), in needs again from a kind of control system of net or parallel network reverse generating.
Background technology
The life that continues to pursue higher standard along with increase and the people of world population.Demand to the energy will continue to increase, and the challenge that faces is how to provide this reliable and continuable energy source, keeps simultaneously the respect to environment.Coal fired power generation and other fossil fuel energy are limited resources, and still, they also cause the harmful effect to environment.Although clearly, regenerative resource when being combined with traditional energy, its sure playing a role, also clearly, renewable resource can not replace traditional energy immediately, deals with problems.
Renewable resource has some shortcomings, and a main shortcoming is that it is to the dependence in geographical position.For example, obtain the optimum position of solar energy in desert area.Yet the client of many needs can not reside in these arid area consumption.Wind power generation too be faced with Geographical Problem.Best available wind energy is at Middle West and llanura, and is same, and this energy-consuming person of great majority is not or not these areas.Another shortcoming of regenerative resource is to have intermittence.When meeting accident, during wind speed decreased, the coal-burning power plant needs more additional energy to remove to remedy energy output.Yet coal-fired power plant can not their raw material supply of fast lifting lacks the wind energy impact that disappeared to support, and therefore, just needs energy storage system and regenerative resource to be used in conjunction with, the impact that is caused to offset intermittence.
Another problem that electrical network faces is the peak of power consumption problem.The time that this problem occurs is in the demand for energy maximum, generally occurs at 5 in afternoon at 7 in evening during this period of time, as shown in Figure 1.In these several hours, the power plant must increase energy recharge to catch up with increasing of energy requirement.In these several hours, the energy that electric power facility consumes is expensive, and this process cost is very high.The price of these increases is normally paid by the commercial and industrial client.At present, the unified tax rate of most of dwelling house client payment; Yet along with the improvement of measurement technology, utility company will collect different rate prices to the electricity consumption of this time period.
In contrast, at dead of night and early morning, energy demand drops to far below energy output between baseline period, in the very cheap practicality of this electric energy of several hours, is fit to the consumer and buys.
Obviously, need an energy storage device to solve energy and use the peak period problem, and the renewable resource intermittent problems.As shown in Figure 2, the impact of the energy storage system of battery (BES).Effective BES system can be in energy resource consumption busy period, and renewable resource provides extra energy intermittent period.The distributed energy storage system is combined with regenerative resource and coal fired power generation, can help electrical network to move more efficiently, simultaneously the wananty costs benefit.
In field of photovoltaic power generation, at present the photovoltaic that utilizes pattern to mainly contain the small off-grid generating of accompanying drawing l of solar energy commonly used utilizes pattern, and the photovoltaic of the large-sized photovoltaic electric station grid connection generating of accompanying drawing 2 utilizes the photovoltaic of the large-scale energy-accumulating power station of pattern and accompanying drawing 3 to utilize pattern etc. several.
The low profile photovoltaic of accompanying drawing l utilizes pattern to be fit to be applied in the occasions such as street lamp, billboard, low profile photovoltaic architecture-integral, the generating of roof, residence from the net generating, because not accepting the scheduling of electrical network, the electric energy that stores is non-loaded consuming and solar battery array can not or be powered to the load to battery energy storage for a long time, cause very large waste, system economy is not high.
Generating electricity by way of merging two or more grid systems of the large-sized photovoltaic power station of accompanying drawing 2 utilizes pattern, uses more.At present, this photovoltaic plant scale is also smaller, and the impact that electrical network is caused of generating electricity by way of merging two or more grid systems is also smaller, when the large-sized photovoltaic power plant construction reaches certain scale, will certainly cause very large puzzlement to electrical network., photovoltaic generation is extremely unsettled, and have daytime, and do not have evening, and even also be extremely unsettled daytime, therefore, electric power system is difficult to dispatching management.A lot of piece solar panels need to be laid in the large-sized photovoltaic power station, conflux through the header box parallel connection after the polylith solar panel series connection again, then are input to the hundreds of kilowatt of many parallel connections even the inverter of MW class, generate electricity through grid-connected inverters.A lot of series-parallel shortcomings of piece solar panel be the output of whole solar battery array be that the poorest string solar cell that generates electricity effect be benchmark, it is serious that solar battery array also is subject to the impact of cloud layer, building shade, dust, temperature, circuit distribution impedance of environment of living in etc., and solar battery array may form
The maximum power point of a plurality of continuous variations.Generally, the maximum power tracing function of solar cell all is to be integrated in the inverter, and therefore, inverter might not be to be operated on the maximum power point of actual the best, causes photovoltaic power station power generation efficient not high, and the photovoltaic plant returns of investment are not high.
The large-scale energy-accumulating power station of accompanying drawing 3 forms in order to alleviate the power supply dispatching problem.When network load is heavy, the electric energy that electric energy or the solar battery array of large-scale energy-storage units array stores can be produced generates electricity through grid-connected inverters, when network load was light, electric energy that can electrical network is unnecessary temporarily was stored in the large-scale energy-storage units array, is prepared for urgent need.The pattern of utilizing this kind can play alleviates the power supply dispatching problem; but this large-scale energy-accumulating power station is built in investment; need acreage property and many large-scale energy storage batteries; conflict with the situation formation that is becoming tight current land resource day; large-scale energy storage also needs to consider with the fail safe of battery centralized configuration; and; wherein certain solar panel, certain storage battery or certain powerful device go wrong when energy-accumulating power station; to make in the energy-accumulating power station large stretch of equipment downtime to be repaired; can't carry out the dispatching of power netwoks instruction; cause significant wastage, investment return reduces.Therefore, be necessary to study new energy storage contravariant generating system and solve the problems referred to above.
