Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated.
1. The user side response terminal:
fig. 4 is a schematic diagram of an architecture of a user-side response terminal. As shown in fig. 4, the user-side response terminal 110 includes: a monitoring module 111, a communication module 112 and a control module 113. Wherein the content of the first and second substances,
the monitoring module 111:
the monitoring module 111 is used for monitoring the indoor temperature T of each user at the moment Tin,i(T), the temperature difference delta T between the indoor water supply and return pipelines at the moment Ti(t), at the moment t, the flow m in the indoor water supply and return pipelinei(t)。
The communication module 112:
the communication module 112 is an information interaction area between the user-side response terminal 110 and the controller 120, and the user-side response terminal 110 monitors the indoor temperature Tin,i(T) temperature difference Δ T between water supply and return in roomi(t) indoor water supply and return pipe inner flow mi(t) upload to its upper level controller 120; and receives a control command from the upper controller 120.
The control module 113:
the communication module 112 transmits the received control command to the control module 113, and the control module 113 regulates and controls the flow rate in the indoor heat supply pipeline according to the control command, so as to achieve the effect of regulating the indoor heat supply.
2. A controller:
referring to fig. 5, an architecture diagram of the controller is shown. As shown in fig. 5, the controller 120 includes: a communication module 121, a calculation module 122 and a storage module 123. Wherein the content of the first and second substances,
the communication module 121:
the communication module 121 is divided into two parts, namely "information interaction with a subordinate user side response terminal" and "information interaction with a user side demand response management platform":
receiving detection and acquisition data uploaded by a terminal, and simultaneously issuing an adjustment control command to the terminal;
receiving weather and user demand parameters issued by the platform, uploading the total regulation potential of the governed user to the platform, and receiving a regulation plan issued by the platform.
The calculation module 122:
the calculation module 122 includes five parts of a neural network model, a comfort model, a heat supply model, a demand response potential and a response plan task decomposition calculation, which are explained in detail below:
2.1, neural network model:
considering that the heat conductivity coefficient, the window-wall ratio and other parameters of the house structure of different users are different, each user needs to be finely controlled, and the outdoor temperature T is received by the communication module at the moment T issued by the platformout(t) outdoor wind speed Vwind(t) outdoor wind direction Dwind(t) and outdoor air humidity
When the weather parameter data establishes the relation among the outdoor temperature, the outdoor wind speed and direction, the outdoor air humidity, the indoor temperature and the indoor required heat supply quantity for each user, namely
Wherein Q isiAnd (t) is the heat supply amount required by the user i at the moment t.
Establishing a neural network model with a three-layer structure:
an input layer: inputting variables related to mass flow to be predicted, wherein the variables are outdoor temperature, outdoor wind speed, outdoor wind direction, outdoor air humidity and indoor temperature, and the number of nodes is 5;
an output layer: the required heat supply amount of the user i is taken as output, and the number of the nodes is 1;
hiding the layer: the patent refers to the following empirical formula for the problem of selecting the number of hidden layer neurons;
wherein n is the number of neurons in the input layer; m is the number of neuron output layers; a is a constant between [1, 10 ]. A is [4, 13], and the excessive number of hidden layer neurons can increase the network calculation amount and easily generate the overfitting problem; if the number of the neurons is too small, the network performance is affected, and the expected effect cannot be achieved, and the number of the hidden layer neurons is selected to be 7 based on the method.
Referring to fig. 6, a schematic diagram of a network structure is shown. As shown in fig. 6, the network may use Sigmoid as the excitation function of the hidden layer.
The neural network model is always trained by taking the latest data, for example, when the training is carried out by using the data of 24 hours per day for 10 days, the data of 10 days needs to be updated in a rolling way so as to correct the parameters of the neural network model.
2.2, comfort model:
professor p.q.fanger classifies PMV into seven levels in table 1 according to the thermal sensation of the human body, and a state in which PMV ═ 0 is the most ideal thermal comfort environment.
TABLE 1 PMV index
| Thermal comfort | Cold | Cool down | Slight cool | Is moderate | Micro-warmer | Heating device | Heat generation |
| PMV value | -3 | -2 | -1 | 0 | 1 | 2 | 3 |
Because the index is influenced by various factors, the calculation is very complex, the influence of air flow rate, air humidity and the like is often ignored in engineering, the index is simplified and processed, and the calculation formula is as follows
Wherein M isiThe human body energy metabolism rate of the user i is related to the activity intensity of the human body; i isclIn winter, the thermal resistance of the clothing is 0.11m2 ℃/W; t issThe average temperature of human skin in a comfortable state may be approximately 33.5 ℃.
IS07730 recommends that the value of PMV should be between-0.5 and 0.5, but different users can determine demand response potential according to their own preference for cold and hot, considering that each person has different preference for cold and hot.
2.3, heat supply model:
when the heat storage electric boiler is used for heating, the heat supply network is adopted on the secondary side, and single-user heating is carried out by adjusting the flow in the water supply and return pipeline when adjusting the indoor heating temperature. The relationship between the heat supply required by the user and the flow is as follows:
Qi(t)＝cmi(t)ΔTi(t)；
wherein c is the specific heat capacity of the hot water in the heat supply pipeline.
2.4, demand response potential:
the load demand response potential at time t of user i is the difference between this regular heat supply and the minimum heat supply required, i.e.:
wherein, δ Qi(t) demand response potential for user i at time t;
the minimum heat supply amount required by the user i at the moment t is related to the minimum comfort requirement (or the minimum temperature requirement) in the user room;
and
and the corresponding flow in the pipe and the temperature difference of the supplied and returned water are respectively used for the user i at the moment t with the minimum heat supply amount for heat supply.
Based on the above process, the flow of solving the response potential demanded by the user i at the time t can be referred to fig. 7.
2.5, response plan task decomposition:
considering that the number of terminals under the jurisdiction of the controller is large, the minimum number of the called terminals is taken as a target when the task is decomposed, namely
Wherein x isi(t) whether the user participates in the response at the moment t or not, and the participation time xi(t) 1, otherwise xi(t)＝0。
In order to achieve the goal of sorting the potentials of all users at the time t from large to small, the screening of the participating users can be performed according to the flow shown in fig. 8.
The storage module 123:
the storage module 123 stores the monitoring data received by the communication module 122 from the terminal and the parameter data transmitted by the platform, so that the calculation module calls the historical data to perform rolling update on the neural network model.
3. The user side demand response management platform comprises:
fig. 9 is a schematic diagram of an architecture of a customer-side demand response management platform. As shown in FIG. 9, the customer-side demand response management platform 130 includes a transaction module 131, an interaction module 132, a calculation module 133, a communication module 134, and a storage module 135. Wherein the content of the first and second substances,
the transaction module 131:
the transaction module 131 includes user registration, contract management, and transaction settlement functions.
User registration is to register the participating users on the platform, each participating user has a separate account, and the account form of the user can be XXX (controller number) -YYY (user number governed by each controller) for facilitating information classification.
Contract management is that participating users sign an electronic contract on the platform according to the response plan allocated before the day and respond according to the contract plan the next day.
And the transaction settlement is carried out according to the actual participation amount of the user after the user participates in the response the next day.
The interaction module 132:
the interaction module 132 is used for realizing online interaction between the user and the platform in a mobile APP or wechat public number manner.
The mobile terminal provides an open account registration function, users participating in demand response perform user registration on line, initiate management service application, and after receiving the service application, the platform performs project management functions such as acceptance and subsequent signing.
In addition, facing the signed user, the platform pushes participation regulation and control request information to the signed user, in order to facilitate the user to operate in time, the load aggregator sends two times of next-day demand response invitation short messages to the user at 12:00 noon and 18:00 pm every day, and the user confirms whether to participate and sets the next-day participation time period on line, and the data set by 22:00 pm is taken as the reference. Considering that part of people is sensitive to temperature values and part of people is sensitive to cold and hot temperatures, the operation habits of setting the interfaces to adapt to different crowds can be divided into two types, and the two types of interfaces can be switched automatically.
