Description
Technical field
The utility model belongs to new forms of energy electric power and supplies with technical field, is specifically related to a kind of many many electric power storages of electric power intelligent balance electric power systems.
Technical background
In the face of global energy is tending towards more and more nervous, more and more deficienter situation, global various countries all make great efforts development and utilization new forms of energy, particularly solar energy and wind energy ubiquitous, it is convenient to utilize, and has formed one of main force of distributed clean energy resource.Along with technological progress and development in science and technology, the technology of solar power generation, wind power generation reaches its maturity, and cost is also more and more lower, adds fostering of government, developed country's applying solar electric power and wind energy electric power develop rapidly, use from present general grid side, the user side application development to using on the spot makes application mode science day by day, business model also is increasingly rationalized, promptly send out i.e. usefulness, the application direction that user side is used and managed, bright and clear day by day.In the face of huge user side distributed new (particularly photoelectricity and wind-powered electricity generation) market, more and more outstanding towards the defective of the prior art of grid side and product.
New forms of energy electric power particularly distributed power (as common wind-powered electricity generation, photoelectricity), because supplying with, its generating and electric power changes with Changes in weather, the output stage instability, can not satisfy the load need for electricity that the user directly uses, supply load uses after the inversion so the distributed power electric power system of prior art all adopts first electric power storage to discharge again, so not only increased after the electric power storage link of inversion again, loss when having wasted the electric energy conversion, and when battery discharging, can not continue charging, waste more distributed power, and, after electric power storage uses up, continue to power again after the charging, this is beyond affordability to the user, and the head it off method of prior art is the quantity that increases generating and storage battery, makes the load of system by maximum load, even if the appearance less than 10% of the situation of peak load, also come configuration-system, increased the investment and the wasting of resources, reduced investment repayment with 100% peak load.
Except that above-mentioned defective, even distributed power is used for charging,, make the charger circuit can not be by its intrinsic optimal algorithm and mode the finish on schedule control and the step of each charging also because of its unstable power, charging effect is had a greatly reduced quality, make the performance of storage battery and life-span be subjected to very big influence.
Prior art and product commonly used mainly contain two modes, and first new forms of energy electric power (as: photoelectricity, wind-powered electricity generation) generating is after power plant's pattern of i.e. grid side application directly is incorporated into the power networks in inversion; It two is to generate power for their own use, and new forms of energy electric power (as: photoelectricity, wind-powered electricity generation) generating back is because its instability, thus be stored in earlier in the storage battery, again by battery discharging after inversion converts alternating current to for user's use, so-called isolated island pattern that Here it is.And new technology from now on to be generation of electricity by new energy use for the user earlier, when use is had a surplus, be incorporated into the power networks power supply or adjustment to other system, just promptly send out promptly and use, the pattern that is incorporated into the power networks of instant user side management of selling, Fig. 1 is exactly existing new technology system and the product principle schematic that can see at present, but its new forms of energy electric power is the user load power supply, remain by the first electric power storage pattern of power transformation again, it mainly is the problem that solves the new forms of energy unstable power, by becoming stable electric power after the electric power storage, inversion is used for user load after converting alternating current to again.
At present, existing new technology system and its defective of product are:
1, as shown in Figure 1, existing new technology system and product are that new forms of energy electric power is through after the inversion, again AC/DC power conversions, charging electric power storage, be electric after DC/DC conversion and the DC/AC inversion again, increased the link of inversion and power conversions, increase investment, also increased the power consumption of power conversions and inversion;
2, new forms of energy electric power charges for charger through DC/DC or through inversion and AC/DC, because the unstable performance of new electricity, make charger at the designed optimal charge control method of battery characteristics, can not carry out, had a strong impact on charging effect and accumulator property and life-span by design;
3, because new forms of energy electric power can not directly be the user load power supply, be to discharge again by first electric power storage to be electric after conversion and the inversion, the charging of storage battery electric power storage at present needs a process, the time of several hrs, thereby the generation of electricity by new energy of prior art, electric power storage, three links of power supply are order serial single task working methods, in the electric power storage process, storage battery can not be powered, and this moment, shortage will appear in the load electricity consumption; In addition, in power supply process, again can not electric power storage, and new forms of energy electric power generated electricity will to waste or be incorporated into the power networks and sold this moment, the new forms of energy electric power of this technical scheme as can be seen, only some (an electric power storage part) is to be that user load is powered.
4, present, make the improved mode of technique scheme increase storage battery quantity exactly more than one times, and be divided into two with top, make when a part of charge in batteries, be electric again by another part storage battery; But will increase the cost and the investment of system so greatly, reduce service efficiency, increase electric cost, reduce investor's investment repayment.
In order to solve the defective that above-mentioned prior art exists, make the generation of electricity by new energy direct inverse become the user load power supply, reduce intermediate link and the conversion times of generation of electricity by new energy to user power utilization, improve the electric power utilance of generation of electricity by new energy, also save system configuration simultaneously, at the hardware that reduces power conversions, and the new forms of energy electric power system is satisfied under the situation of the required supply of electric power of equal user load, can reduce the outfit of storage battery, reduce system's scale of investment, improve the investment and the level of resources utilization.For this purpose, the present utility model has proposed a kind of many many electric power storages of electric power intelligent balance electric power systems.
