In addition, the process of the power grid balance scheduling of the electricity users can be described as peak clipping and valley filling transactions, so the specific peak clipping transaction clearing mode and basis are as follows: the power utilization users report and reduce the capacity and the response price, the peak clipping capacity requirement of the operation day is taken as an upper limit in a mode of centralized bidding and marginal clearing according to the principles of time priority and capacity priority, when the reported capacity does not reach the capacity requirement, the reported capacity is completely cleared, and the clearing price is the price reported by calling the last power utilization user; and if the declared capacity exceeds the capacity demand in the time period, the clearing price is the price declared by the last power utilization user called before the clearing capacity reaches the declared capacity. And clearing to obtain the response capacity and the response electricity price of the corresponding time period of the operation day, wherein the clearing result is an execution basis of the electricity user on the operation day.
The specific way and basis for clearing the grain filling transaction are as follows: the power utilization users report the capacity increase and the response price, the centralized bidding and marginal clearing mode is adopted, the operation day valley filling capacity requirement is taken as an upper limit according to the principles of price priority, time priority and capacity priority, when the reported capacity does not reach the capacity requirement, the reported capacity is completely cleared, and the clearing price is the price reported by calling the last power utilization user; and if the declared capacity exceeds the capacity demand in the time period, the clearing price is the price declared by the last power utilization user called before the clearing capacity reaches the declared capacity. And clearing to obtain the response capacity and the response electricity price of the corresponding time period of the operation day, wherein the clearing result is an execution basis of the electricity user on the operation day.
The specific transaction effect evaluation method comprises the following steps: aiming at the actual response effect of calling the current day, the execution effect of the invitation type response transaction is that whether the electricity user carries out peak clipping response according to the bid winning capacity or not is determined through the load baseline, the difference value between the actual load and the baseline load in the response time is used for calculation, the P response capacity is greater than 0 and is effective response, and the P response capacity is smaller than or equal to 0 and is ineffective response.
The evaluation formula of the solicited response peak clipping transaction is as follows:
Presponse capacity＝PBaseline average load-PActual load
The invited-response-to-fill-in-valley transaction evaluation formula is as follows:
Presponse capacity＝PActual load-PBaseline average load
The baseline determination principle is as follows: the load curve of the power consumer corresponding to the response period is taken as the baseline by selecting the last 5 normal production working days before the load response D-1 day. The average load calculated from the baseline is referred to as the baseline average load. The base line of the electricity user is obtained by summing the base lines of all the users integrated by the electricity user.
The specific criteria for evaluating the transaction effect are as follows: and if the user meets the condition that the response quantity of the response time period is more than or equal to 80% of the response capability confirmation value in the response process, the response is regarded as a valid response, and otherwise, the response is regarded as an invalid response. The difference is greater than 120% of the response capability confirmation value, calculated as 120% of the response capability confirmation value.
The settlement fee for the peak clipping transaction is the electric energy fee, the settlement is carried out by multiplying the actual effective response capacity by the settlement price, and the settlement price is a larger value of the uniform electricity price at the real-time market load side and the clearing price for the peak clipping transaction;
the specific formal settlement mode is as follows: the electricity user issues the compensation fee to the proxy user according to the proxy relation. The peak clipping transaction settlement cost is electric energy cost, the actual effective response capacity is multiplied by the settlement price to settle, and the settlement price is a larger value of the real-time market load side unified electricity price and the peak clipping transaction clearing price; the settlement fee of the valley filling transaction is the electric energy fee, and the actual effective response capacity is multiplied by the price of the clear electricity generated by the valley filling transaction to settle.
The settlement formula of the solicited response peak clipping transaction is as follows:
R＝∑(Qeffective response power, t×PSettlement of electricity price t)
Wherein R is the user's revenue for participating in an solicited response (peak clipping) transaction; qEffective response power, tEffective response electric quantity for t-period of time of the user participating in the invitation type response peak clipping transaction; pSettlement of electricity price tAnd settling the larger value of the unified power price and the clear power price at the load side in the real-time market transaction time period.
Further, the settlement fee of the valley filling transaction is the electric energy fee, and the actual effective response capacity is multiplied by the price of the clear electricity generated by the valley filling transaction to settle;
the invited-response-to-fill-in transaction settlement formula is:
R＝∑(Qeffective response power, t×PClearing price, t)
Wherein R is the revenue of the user's participation in an solicited response (fill-in-valley) transaction; qEffective response power, tEffective response electric quantity of a user participating in an invitation type response valley filling transaction at a time t; pSettlement of electricity price tThe clearing price for the trading session solicited response valley fill trade.
Furthermore, the invitation type response peak clipping trading beneficiary is all the power users, the peak clipping trading started by the power grid invitation is shared by market users and power grid enterprises, when the clear power price does not exceed the real-time market load side unified power price, the market users bear the clear power price, and when the clear power price exceeds the real-time market load side unified power price, the exceeding part of the fee is borne by the power grid enterprises, and the surplus is dredged in the power transmission and distribution price.
When the real-time market load side unified electricity price is not exceeded, the real-time market load side unified electricity price is borne by market users, and the specific market users are shared in the following mode: and carrying out apportionment according to the actual power consumption proportion.
Then, the calculation formula of the allocated cost that the ith marketized user needs to bear is as follows:
in the formula, RTotal costServing the total current day for an invited response transaction, FjThe electricity consumption of the transaction period is the jth marketized user, and M is the total number of the marketized users in the transaction period on the same day.
The specific power generation enterprises share the following modes: and carrying out apportionment according to the actual internet electricity quantity proportion of the transaction time interval.
Then, the calculation formula of the shared cost needed to be borne by the jth power plant is as follows:
in the formula, FjThe online electricity quantity of the jth power plant in the transaction period is obtained. And M is the total number of the online power generation plants in the transaction period.
In addition, the inviting type response valley filling transaction beneficiary is a new energy power plant and a machine set which does not participate in peak shaving, and the market cost is proportionally shared by the new energy power plant and the machine set which does not participate in peak shaving.
The specific power generation enterprises share the following modes: and carrying out apportionment according to the actual internet electricity quantity proportion of the transaction time interval.
Then, the calculation formula of the shared cost needed to be borne by the jth power plant is as follows:
in the formula, FjThe time of the transaction for the jth power plantAnd the online electricity quantity of the segment. And M is the total number of the online power generation plants in the transaction period.
The method is different from the prior art, and provides a power load side resource invitation type response scheduling method, which takes power users as market main bodies, aggregates load side resources with minute-level or hour-level response capability to send out an invitation in the day ahead, and participates in daily peak clipping and valley filling trading of bidding. And the invitation-type response transaction bidding users execute the bidding results according to the day-ahead results on the operation day. When the predicted value of the highest load is adjusted to a certain value according to the next day, sending a peak clipping requirement; and (4) when the lowest load is lower than a certain value according to the next day, sending out a valley filling requirement.
Example two
In one or more embodiments, a power load side resource-solicited response scheduling system of the present disclosure, the database server: receiving and storing the power utilization user information with minute-level or hour-level response capability and invited by the user in the day ahead, and participating in a bidding day power grid load scheduling strategy;

The electricity users participate in market declaration, and declaration information comprises response capacity, capacity price and the like.
And on the operation day, the peak load removal/valley fill resources are called by sending a load adjustment instruction to the electricity user. And evaluating the power utilization users who do not execute the calling task in a credit evaluation system.
And releasing a formal settlement basis by taking monthly periods as a period according to the daily clearing and monthly settlement, and issuing the compensation fee to the deputy user by the power utilization user according to an agency relationship.
The settlement fee for the peak clipping transaction is settled by multiplying the actual effective response capacity by the settlement price, wherein the settlement price is a larger value of the real-time market load side unified electricity price and the peak clipping transaction clearing price;
includes a transaction settlement fee for the fill transaction, which is settled by multiplying the actual effective response capacity by the price of the electricity paid for the fill transaction.
The invited response (peak clipping) transaction settlement formula is:
R＝∑(Qeffective response power, t×PSettlement of electricity price t)
Wherein: r is the revenue of the user's participation in an solicited response (peak clipping) transaction;
Qeffective response power, tEffective response electric quantity for t time period of participation of the user in an invitation type response (peak clipping) transaction;
Psettlement of electricity price tAnd settling the larger value of the unified power price and the clear power price at the load side in the real-time market transaction time period.

Wherein: r is the revenue of the user's participation in an solicited response (valley fill) transaction;
Qeffective response power, tEffective response electric quantity for t period of time of participation of the user in an invitation type response (valley filling) transaction;
Psettlement of electricity price tThe clearing price of the transaction is solicited for the transaction period in response (fill-in).
The invited type response (peak clipping) transaction beneficiary is all the power users, because the peak clipping transaction started by the power grid invitation is shared by market users and power grid enterprises, when the clear price does not exceed the real-time market load side unified price, the market users bear the clear price, and when the clear price exceeds the real-time market load side unified price, the excess part of the cost is borne by the power grid enterprises, and the surplus cost is dredged in the transmission and distribution price.
