Fig. 1 shows a flow chart of a method provided by an embodiment of the invention.
Specifically, the method for intelligent control of aggregation of user flexible resources specifically comprises the following steps:
and S101, hierarchically polymerizing the user-side flexible resources to a polymerization layer based on the energy utilization genes.
In the embodiment of the invention, the adjustable starting time, the adjustable time interval length, the user participation rate, the user response degree and the credible adjustable potential predicted value of the user flexible load resource are taken as the energy using genes, and the flexible load resource is hierarchically and hierarchically aggregated to the aggregation layer based on the energy using genes. Specifically, the aggregator signs a resource hosting protocol with the user according to the flexible load resource cluster.
It can be understood that the flexible load resource refers to an electric power flexible load, and is a load with flexible characteristics, which can actively participate in the operation control of the power grid, and can perform energy interaction with the power grid. Load compliance appears to be flexible over a period of time. The scheduling and adjustment of the flexible load is one of the important means for relieving the contradiction between supply and demand. The flexible adjustment capability of the flexible load changes the history of unidirectional and passive load adjustment, and changes the characteristics of rigidity, uncertainty and the like of load parameters. In addition, the access of the electric automobile and the distributed power supply enables the load to have a certain power supply function. Electrical flexible loads belong to the regulated loads, for example: air conditioners, electric vehicles, and the like.

It can be understood that the user response refers to a response condition of a certain user group, the user participation rate reflects a proportion of the user participation response, the user response degree represents a response execution degree of the user, and the definition of the reliability index for measuring the response load can be performed according to the reliability index of the conventional demand response, specifically:
setting participation status of single user demand responseComprises the following steps:in the formula (I), wherein,calculating the user participation rate for the user response state, wherein the probability that the user response meets the response requirement is represented by the user response participation rateWherein n represents the total number of users, a demand response contract signed by a user side and a power grid specifies that the demand response is lightened, but the actual response electric quantity has certain randomness due to the influence of uncertain factors, in order to evaluate the demand response reliability under the influence of uncertain factors, the response degree of the demand response is defined, as shown in the following formula, the ratio of the capacity of the users participating in the response to the total controllable capacity of the users is the user response degreeWherein, in the step (A),in order to be able to participate in the capacity of the user to respond,total capacity for the user group;
it is to be understood that aggregating user responses refers to certain aggregationsThe response condition of the user group, the response concurrence rate represents the power utilization condition of the aggregation user in a certain period, and the aggregation response degree represents the response execution degree of the aggregation user, specifically: describing the degree of mutual overlapping power utilization of users at the same time by using the concept of response simultaneous rate, wherein the simultaneous rate of aggregated users represents the proportion of the users in the power utilization state at the time t in all users, and introducing variablesThe power utilization state of a user is represented, and the power utilization state of a user k at a moment t is
In the formula (I), wherein,a value of 0 indicates that user k is in a non-powered state at time t, i.e.The time indicates that no electric quantity is consumed by the user k at the moment t, and the simultaneous rate of the aggregated users is defined asWherein K represents the total number of users of the aggregation user, and the response degree of the aggregation user isWherein i represents the total number of aggregated users,、、respectively representing the participation rate, the response degree and the power of the aggregation user,representing the degree of response of the aggregated user;
it can be understood that, for the user response reliability evaluation method, it is assumed that the number of devices which can respond owned by the user is p, and the online rate of the ith device is pAccording to historical data of the user in a certain period, the expected response load of the user is ranked, and the response potential is considered as the online rate of the 1 st responder deviceWhen the equipment is in off-line state, its continuous load curve is availableEquivalent to a continuous load curve shifted to the right by the load of C, considering the online situation of this plant, the continuous load curve of the aggregated users becomes:wherein, in the step (A),is the on-line rate of the 1 st device,sequentially considering the online rates and the failure rates of p devices as the offline rate of the 1 st device, continuously changing the continuous load curve of the user, considering the online rate of the ith device, and obtaining the continuous load curveThe total responsibilities of p devices held by the user areThe maximum equivalent load is,The method is the area enclosed by the initial equivalent continuous load of a user and a continuous load curve after the indexes such as the online rate of equipment and the like are considered, and the physical meaning of the method is that the reduction of the response potential of the user due to the offline of the equipment in response to the load isTotal capacity of total responsibilities of p devices held by userIs composed of
When the convolution operation of all the responsive devices of the user is finished, the actual value of the responsive potential of the user can be calculated after correctionIs composed ofExpected value of degree of response of userAccording to the corrected actual response potential value of the user, the credible response degree of the user can be obtained as;
It can be understood that, for the user aggregation response reliability evaluation method, a continuous load curve is obtained according to the historical load data of the aggregation users, and the simultaneous rate and participation of the aggregation users are consideredThe rate is corrected for the sustained load curve. Let the number of aggregated users be q, the concurrency rate be s, and the participation rate of user j beThe calculation steps of the aggregation user continuous load curve obtained based on the user continuous load curve calculation method are as follows: step one, considering that a first aggregation user has p pieces of responsive equipment together, and the online rate of the 1 st piece of responsive equipment isThe response potential isWhen the equipment is in off-line state, its continuous load curve is availableRepresenting the load corresponding to the sustained load curve shifted by C to the right, the sustained load curve for the aggregated users becomes, taking into account the on-line condition of the plant
(ii) a Step two, sequentially considering the online rate of p devices of the first aggregation user, continuously changing the continuous load curve of the aggregation user, considering the online rate of the ith device, and obtaining the continuous load curve(ii) a Step three, when the online rates of p devices are considered, the equivalent load curve is
for considering the continuous load curve after the first aggregation user participation rate,The probability that the user is not involved in the response is aggregated for the first,a response potential reduction resulting from non-engagement of the response for the first aggregated user; step four, repeating the above processes, finally considering the participation rate of the qth aggregation user, and correcting the continuous load curve according to the following formula to obtain the equivalent continuous response load curve of the aggregation user as
to account for the sustained load curve after the qth aggregated user engagement rate,for the qth aggregate user engagement rate,a reduction in response potential for the q-th aggregated user to not participate in a response. The total potential of all users in a certain area to respond isMaximum equivalent load of,Aggregating the area surrounded by the initial equivalent continuous load of the user response potential and the continuous load curve after considering the indexes of the user concurrence rate, the participation rate and the like for the area, wherein the physical meaning of aggregating the area is that the response potential of the user response potential is caused by the fact that the user response load is offlineThe amount of reduction of (c).
When the concurrency rate and the participation rate of q aggregated users are considered, the continuous load curve isThe total response potential is,
Because of the influence of the response concurrency rate, participation rate and response degree of the aggregated user, the response potential of the equipment responded by the aggregated user cannot reach the value of the expected response potential, and after the convolution operation of all the equipment responded by the user is finished, the actual value of the response potential of the user can be calculated after the correctionWherein:suppose that the expected value of the total response degree of the power grid company to the aggregated user isBecause the aggregated user is not online or refuses to participate at the response moment, the response potential of the user is reduced, the actual response degree of the aggregated user cannot reach the theoretical value according to the corrected actual response potential value of the aggregated user, and the credible response degree of the aggregated user can be obtained as;
It can be understood that for the construction of the multi-user credible and adjustable potential prediction model, the influence factors of the multi-user credible and adjustable potential are complex, and the adjustment potential which can be finally achieved is calculated by comprehensively considering factors such as electricity price, an excitation mechanism, equipment failure rate, communication equipment reliability, user response willingness and the like.

In particular, the method comprises the following steps of,
