Embodiment
To be described one exemplary embodiment of the present invention in conjunction with the accompanying drawings hereinafter.For clarity and conciseness, all features of actual execution mode are not described in specification.Yet, should understand, in the process of any this practical embodiments of exploitation, must make a lot of decisions specific to execution mode, so that realize developer's objectives, and these decisions may change to some extent along with the difference of execution mode.In addition, might be very complicated and time-consuming though will also be appreciated that development, concerning the those skilled in the art that have benefited from present disclosure, this development only is customary task.
At this, what also need to illustrate a bit is, for fear of having blured the present invention because of unnecessary details, only show in the accompanying drawings with according to the closely-related apparatus structure of the solution of the present invention, and omitted other details little with relation of the present invention.
As the background technology part illustrated, the electric energy balance that the electric energy that people always wish generator and provided is consumed with power consumption equipment as much as possible reaches whole power system stability thus and moves reliably.For this reason, can provide AGC to instruct according to the running status of electrical network usually, require generator to instruct and export electric energy according to this AGC to generator.One skilled in the art will appreciate that the actual power consumption measurer in the electrical network has certain rules, for example power consumption is less morning in certain zone, along with the arrival power consumption of operating time increases, to night power consumption reduce again.Control centre in the electrical network can add up the Changing Pattern that draws the power consumption in the electrical network, and correspondingly formulates the generation schedule of generator in advance.For example, the generation schedule that the control centre can pre-establish this in advance offers corresponding generator, so that generator can generate electricity according to this predetermined energy output in definite period.
Yet because with the fluctuation and the randomness of motor institute consumed power, perhaps even because the catastrophic failure of equipment in the electric power system, the actual power consumption amount in the electrical network has deviation with the power consumption of pre-estimating usually.If it is excessive that the electric energy that all generators provided and the actual power of electrical network consume deviation, then the safe and stable operation of entail dangers to electric power system.
In order to overcome above-mentioned shortcoming, existing scheme major part all is to pay close attention to the improvement of electrical network aspect, and the improvement of shorter mention power plant (generator) aspect.Because one skilled in the art will appreciate that if require power plant's (generator) is carried out structure of modification, relate in one aspect to huge improvement cost, structure of modification can't overcome the influence of machinery inertial to generating on the other hand.
Yet the inventor can adopt the control method of the energy storage device in the embodiment of the invention and the ability that equipment significantly improves the balancing power network load fluctuation of existing power plant through discovering.Specifically describe below.
As described above, though the control centre of electrical network can offer corresponding power plant with predetermined energy output in advance, yet owing to use the contingency and the randomness of motor institute consumed power, the actual power consumption amount in the electrical network has deviation with the power consumption of pre-estimating usually.Therefore, in the practical application, the electric power system meeting sends automatic generation control (AGC) instruction according to real-time running state and gives generator, requires generator to instruct according to this AGC and generates electricity.The curvilinear motion that one skilled in the art will appreciate that predetermined generation schedule is slow usually, changed once in for example per 15 minutes or 30 minutes, yet the AGC instruction is a real-time change, therefore changes than very fast.AGC instruction may several minutes or even the several seconds within just change.Generator in the power plant is plant equipment normally, owing to its machinery inertial was difficult to quickly respond to and finish the AGC command request in the so short time.
The inventor notices, though the AGC instruction changes ratio comparatively fast, yet it always centers on the curve fluctuation of the energy output of pre-estimating, and can't be too far away partially.Because the electric energy that the machinery inertial of generator causes generator to produce is difficult to the requirement of the AGC instruction of quick response change, therefore, the generating equipment that the embodiment of the invention is used comprises energy storage device and generator, makes the output of whole generating equipment respond the AGC instruction better.
Therefore, according to one embodiment of the invention, provide the control method of energy storage device, be used to control generating equipment and export electric energy to electrical network, described generating equipment comprises generator and energy storage device, and the maximum power of described energy storage device is P
