Third target establishes micro- the second Optimal Operation Model that can be netted of the industrialized agriculture；
Based on second Optimal Operation Model, within the dispatching cycle, adjust every in the micro- energy net of the industrialized agriculture
One can time shift load corresponding working hour and the industrialized agriculture it is micro- can net in each energy storage device storage state, determine
Meet simultaneously industrialized agriculture when second target and the third target it is micro- can in net it is each can time shift load it is corresponding
The storage state of each energy storage device in working hour and the micro- energy net of the industrialized agriculture；
Wherein, second preset condition cannot meet for the photovoltaic output total amount in the micro- energy net of the industrialized agriculture
It is all can time shift load consumption energy summation or the photovoltaic output total amount meet it is described it is all can time shift load consumption
Energy after exist sell surplus.
Specifically, preceding description needs judge the micro- photovoltaic output total amount that can be netted of the industrialized agriculture within dispatching cycle
Whether first preset condition is met, i.e. whether photovoltaic output total amount meets and be only capable of meeting in the micro- energy net of the industrialized agriculture and own
Can time shift load consumption energy summation.If photovoltaic output total amount is unsatisfactory for the first preset condition, that is, it is divided into two kinds of situations, it is a kind of
Situation be photovoltaic output insufficient total amount with meet industrialized agriculture it is micro- can in net it is all can the consumption of time shift load energy summation, at this time
Need at power grid buy electric energy be supplied to industrialized agriculture it is micro- can net in can time shift load.Another situation is that photovoltaic is contributed always
Measure meet industrialized agriculture it is micro- can net in it is all can time shift load consumption energy summation after, also remaining energy can go out
It sells, that is, exists and sell surplus.That is, it is pre- to meet second just when photovoltaic output total amount is unsatisfactory for the first preset condition
If condition, i.e. the first preset condition and the second preset condition are mutual exclusion conditions.
In general, photovoltaic output total amount meet the first preset condition when, industrialized agriculture it is micro- can net in it is all can time shift load disappear
The energy summation of consumption and the ratio of the photovoltaic output total amount meet formula (1), then are preset when photovoltaic output total amount meets second
During condition, industrialized agriculture it is micro- can in net it is all can the ratio of energy summation and the photovoltaic output total amount of time shift load consumption expire
