Background technology
Under the overall situation of energy scarcity, the reproducible clean energy resource energy ring for having come into average family progressively
In border.Wherein, solar energy is most easily one of clean energy resource used in various regenerative resources.Under such overall background,
Also many solar energy peripheral equipments have been expedited the emergence of, our MeBoost is exactly to arise at the historic moment under such overall situation.
MeBoost is one for, in solar energy power utilization environment, realizing load (for example, the boiler equipment to purely resistive
Deng) according to solar electrical energy generation situation, output is adjusted, it is achieved thereby that in the premise for not affecting family to use orthobiosiss
Under, energy resource consumption is reduced to greatest extent and improves energy use efficiency.At present, similar equipment (master is being there is also on the market
Will market in overseas, domestic our first at present), but generally existing problem below：
Output adjustment response cycle is long
It is adjusted using trial strategy mostly, by progressively adjusting, this output adjustment mode of infinite approach,
Actual value after adjusting every time will carry out comparison repeatedly with desired value and calculate again, due to voltage and the random change of load
Change, repeatedly adjustment can be only achieved expection to cause needs, also, the probability for occurring adjusting repeatedly is very big.In sum, result in
The response cycle of output adjustment extends.
Output adjustment decision-making is inaccurate
Using " collection->Adjustment->Collection->The such adjustment decision-making of adjustment " or simple weighted average are determined
Plan, result in, and the output after adjustment is greatly likely to occur following result：
The practical situation of solar electrical energy generation and household electricity can not really be reflected, so as to, cause user it is excessive from electricity
Net power taking；
There is being adjusted repeatedly in the output short time, cause output unstable, affect terminal unit
Service life
The desired value of output adjustment is larger with actual value error
Due to electrical network and the randomness of power utilization environment, the error between the desired value and actual value of output adjustment can be deposited
In larger nonlinear wave, it is generally the case that this error is all floated in the scope of 50W～200W.
