setting sigma Pn as the household power demand, sigma Ps household power supply (energy storage and storage), combing the total supply and demand, etc.; d is the exchange price, DpeakFor peak electricity price, DvalleyThe price of electricity used in the valley.
1. When the sigma Ps is less than or equal to 10 percent of sigma Pn, the power supply quantity is less than or equal to 10 percent of the power demand quantity;
matching supply prices and demand prices by a trading center; the highest price is as follows: dmax＝Dpeak。
2. When the power consumption supply amount is larger than the power consumption demand amount + 10%, the exchange price P is the average value of the peak price and the valley price when the Sigma Ps is larger than 10% of the Sigma Pn;
3. when the 10% Σ Pn is not more than Σ Ps and not more than 20% Σ Pn, that is, the supply and demand electric quantity is not less than 10% and not more than 20% of the required electric quantity;
price matching of supply and demand by a trading center, maximum price:
Dmax＝(Dpeak+Dvalley)/2。
4. when 20% Σ Pn is not more than Σ Ps not more than 50% Σ Pn, that is, the supply and demand electric quantity Σ Ps is not less than 20% and not more than 50% of the required electric quantity;
deal transactions, the price of supply and demand are "forward auctioned" for a maximum price:
Dmax＝80％Dpeak。
the auction proceeds in increments of + delta in units of minutes, corners (renminbi).
5. When the power supply and demand are not less than or equal to the Σ Pn by 100% or more than or equal to the Σ Ps and not less than 50% or more than or equal to the Σ Pn, the power supply and demand is less than or equal to 100% and more than 50% of the power demand;
trade, the price of supply and demand is "reverse auctioned" for a maximum price: dmax＝120％Dvalley。
The-delta decrement value of the reverse auction can be minutes and corners (RMB). The bidding (matching) process in one embodiment of the present invention is described as follows:
bidding (matching) process:

1) Aggregate bidding:
a time period is set for the aggregate bid time each day. During the aggregate bidding period, the automatic matching system of the trading system only stores but does not match, and when the bidding time is declared to be over, the matching system generates the price of the current day according to the aggregate bidding principle.
2) And (4) continuous bidding:
successive price bidding transactions are conducted over a fixed period of time.
Bidding (match) principle:
1) the matching system automatically matches according to 'price priority and time priority', and matches in sequence according to time sequence when the price is the same.
2) Then, the electricity consumption quantity Σ Pn and the supply quantity Σ Ps are counted every day or each time, and the price is determined according to the bidding rule shown in table 1:
| quantity comparison | Price |
| a)ΣPs≤10％ΣPn | Dmax＝Dpeak |
| b)10％ΣPn≯ΣPs≤20％ΣPn | Dmax＝(Dpeak+Dvalley)/2 |
| c)20％ΣPn≯ΣPs≤50％ΣPn | Dmax＝(Dpeak+Dvalley) 2+ Forward Bidding (+ Delta) |
| d)100％ΣPn≥ΣPs≮50％ΣPn | Dmax＝(Dpeak+Dvalley) /2+ reverse bid (-delta) |
After the transaction, the stored electricity quantity is automatically increased to the power grid, the power grid is allocated according to the transaction result, and then the electricity demand user automatically charges according to the transaction price.
In this embodiment, the transaction time period set by the user and the "energy storage margin transaction time range" counted by the transaction server include, but are not limited to, minute meter, hour meter, month meter and year meter.
