[0063] The following embodiments refer to Figs. 1 to 4.

[0064] The embodiments of the present application provide a user-side integrated energy network coordination control method, which is applied to a user-side integrated energy network coordination control system.

[0065] Step S01: obtaining a user carbon emission total limit value in a preset period in the integrated energy network coordination control platform;

[0066] The preset period can be set to one year or half a year, and can be set according to experience and actual conditions.

[0067] Step S02: obtaining the node total number of each loop in the user-side integrated energy network and the energy supply and consumption data between any two nodes in the preset period, and calculating the carbon emission responsibility factor measured value of each node;

[0068] The historical energy supply data of each power supply node and the historical energy consumption data of each load node in the network are collected by setting the collection terminal in the user energy supply loop and the user load loop, and the measured value of the carbon emission responsibility factor can be obtained by calculating and processing the corresponding collected data.

[0069] Specifically, the node total number of each loop in the user-side comprehensive energy network and the energy supply and consumption data between any two nodes in a preset period are obtained, and the measured value of the carbon emission responsibility factor of each node is calculated.

[0071] S22, the carbon emission of each loop transmission unit energy flowing into each node is obtained, and the carbon flow density matrix of each loop of the user-side comprehensive energy network at time t is constructed according to the carbon emission.

[0072] Taking the energy supply node in the energy supply loop of the user-side comprehensive energy network as the starting point, the carbon emission factor (carbon emission) of each loop and each node in the network per unit time can be sequentially calculated according to the carbon flow density of the energy flow of all loops flowing out of the node and the carbon emission factor per unit time of the node.

[0073] S23, the carbon flow distribution matrix per unit time of each loop at time t is obtained according to the energy flow distribution matrix and the carbon flow density matrix.

[0074] S24, the measured value of the carbon emission responsibility factor of each node of each load loop of the user-side comprehensive energy network is calculated according to the carbon flow distribution matrix and the node total number.

[0075] The measured value of the carbon emission responsibility factor of each node is equal to the sum of the corresponding node elements in the unit time carbon flow distribution matrix of each loop in the network.

[0076] Step S03, calculating the actual value of the total carbon emission of the user according to the measured value of the carbon emission responsibility factor and the node total number;

[0077] Step S04, comparing the actual value of the total carbon emission of the user with the limit value of the total carbon emission of the user to determine whether the total carbon emission of the user is overdue.

[0078] A warning proportion weight value can be set, such as 90%, when the actual value of the total carbon emission of the user reaches 90% of the limit value of the total carbon emission of the user, the first warning warning is issued; when the actual value of the total carbon emission of the user reaches the limit value of the total carbon emission of the user, the overdue warning is issued.

[0079] Step S05, when the total carbon emission of the user reaches the alarm state, the user is sent a warning information, the user updates the actual total carbon emission limit value after performing the responsible cut-off, and step S06 is performed;

[0080] Specifically, when the total carbon emission of the user reaches the alarm state, the user is sent a warning information, the user updates the actual total carbon emission limit value after performing the responsible cut-off, and step S06 is performed.

[0081] When the total carbon emission of the user is greater than the timeout warning value, the user is sent a warning information that the total carbon emission is about to timeout, and each load node in the network is arranged in descending order according to the total carbon emission responsibility factor and pushed to the user, and the user selects the load for cut-off;

[0082] When the total carbon emission of the user is greater than the timeout warning value, the user is sent a warning information that the total carbon emission has timed out, and the user selects the load for cut-off, and the platform updates the actual carbon emission and performs step S06.

[0083] Step S06, the predicted data of energy supply and use of any two nodes in each loop of the user side comprehensive energy network at t time is obtained by using an autoregressive time series model, and the predicted value of the carbon emission responsibility factor of each node at t time is calculated.

[0084] Specifically, the predicted data of energy supply and use of any two nodes in each loop of the user side comprehensive energy network at t time is obtained by using an autoregressive time series model, and the predicted value of the carbon emission responsibility factor of each node at t time is calculated.

[0085] S61, the predicted data of energy supply and use of any two nodes in each loop of the user side comprehensive energy network at t time is obtained by using an autoregressive time series model, and the predicted value of the carbon emission responsibility factor of each node at t time is calculated.

[0086] S62, the predicted value of the carbon emission responsibility factor of each node in each load loop of the user side comprehensive energy network at t time is calculated according to the carbon flow distribution prediction matrix and the total number of nodes.

[0087] Step S07, the carbon emission high penetration limit value of each node is obtained according to the predicted value of the carbon emission responsibility factor;

[0088] Step S08, the comparison between / between any two of the measured value of the carbon emission responsibility factor, the predicted value of the carbon emission responsibility factor and the carbon emission high penetration limit value is performed, and the comparison result is obtained.

[0089] Step S09, the operation mode of each node is set or the execution instruction is issued to the instruction execution device of each node loop to perform the corresponding action according to the comparison result. Specifically, the following several cases are included:

[0090] (1) if the comparison result is carbon emission responsibility factor predicted value < carbon emission responsibility factor measured value < carbon emission high crossing limit value, then the user is prompted for short-term abnormal carbon emission of the corresponding node, and the original operation mode of the corresponding node is maintained;

[0091] Preferably, the corresponding action according to the comparison result includes:

[0092] (2) if the comparison result is carbon emission high crossing limit value < carbon emission responsibility factor predicted value, then the user is warned of short-term over-limit carbon emission of the corresponding node, and the user selects to maintain the original operation mode of the corresponding node or issues an execution instruction to the instruction execution device of the corresponding node loop according to the load adjustability of the corresponding node to execute a corresponding action.

[0093] Specifically, the user issues an execution instruction to the instruction execution device of the corresponding node loop according to the load adjustability of the corresponding node to execute a corresponding action, which includes:

[0094] If the corresponding node is a non-flexible adjustable load, then at t+1, a disconnection instruction is issued to the instruction execution device in the energy supply loop of the corresponding node, and the instruction execution device executes a disconnection action;

[0095] If the corresponding node is a flexible adjustable load, then the integrated energy network coordination control platform calls and receives the real-time load adjustable capacity of the corresponding node, and calculates the load adjustment route based on the load adjustable capacity, energy supply and consumption data, and predicted data of energy supply and consumption. At t+1, a load control instruction is issued to the instruction execution device in the energy supply loop of the corresponding node, and the instruction execution device executes a load control action.

[0096] In this embodiment, for the load node whose actual carbon emission exceeds the high crossing limit value, appropriate action instructions are taken according to the flexible adjustment capability of the node.

[0097] (3) if the comparison result is carbon emission responsibility factor measured value < carbon emission responsibility factor predicted value, then it is determined whether the corresponding loop is on;

[0098] If the loop is in the on state, the user selects to maintain the original operation mode of the corresponding node, and if the loop is in the off state, then S06 to S07 are repeated at t+1 to calculate the latest carbon emission high crossing limit value of the corresponding node, and the carbon emission responsibility factor measured value is compared with the latest carbon emission high crossing limit value;

[0099] If the carbon emission responsibility factor measured value is less than or equal to the latest carbon emission high crossing limit value, then the original operation mode of the corresponding node is maintained;

[0100] If the measured value of the carbon emission responsibility factor is greater than the latest carbon emission high-crossing limit, an execution command is sent to the instruction execution device of the corresponding node circuit to perform the corresponding action.

[0101] The present invention provides a user-side integrated energy network coordination control method. By running a coordination control strategy based on carbon emission responsibility factors and setting the operating mode of nodes or issuing action commands to each load loop command execution device to perform corresponding actions according to the strategy results, it can ensure that the carbon emissions per unit time and the total carbon emissions of the user-side integrated energy network meet the limit requirements.

[0102] To explain the solution of this application, another embodiment of the user-side integrated energy network coordination and control method of the present invention is described in detail below:

[0103] Step 1: Input the user's annual carbon emission limit into the integrated energy network coordination and control platform, and record it as... ;

[0104] Step 2: Any energy supply, consumption, or distribution device in the user-side integrated energy network is considered a network node. Through the data acquisition terminal, the hourly energy supply and consumption data for loop ij (from node i to node j) over the past 7 days are entered into the platform and recorded as follows: The unit is uniformly kW, and there is no path between node i and node j. Set to 0;

[0105] Step 3: Construction Energy flow distribution matrix of each loop in the user-side integrated energy network at any time If the total number of network nodes is N, then the matrix It should be an N-order matrix, where the element in the i-th row and j-th column is... Assignment;

[0106] Step S04: Calculation At time i, the carbon emissions (carbon emission factor per unit time) caused by node i producing or consuming one unit of energy are denoted as: Unit: kgCO2 / kW. If the total number of nodes in the user-side integrated energy network is N, for energy supply node i in the network's energy supply loop, the carbon emission value (carbon emission factor per unit time) caused by its production of one unit of energy is assigned using the following rules:

[0107] a) The carbon emission factor per unit time of the photovoltaic power generation system is 0;

[0108] b) Carbon emission factor per unit time for wind power generation system = 0;

[0109] c) Carbon emission factor of gas power generation system per unit time = gas consumption x natural gas carbon emission factor / power generation (natural gas carbon emission factor reference value 2.02 kgCO2 / Nm³);

[0110] d) Carbon emission factor of thermal power generation system per unit time = coal consumption x standard coal carbon emission factor / power generation (standard coal carbon emission factor reference value 2.72 kgCO2 / kgce);

[0111] e) Carbon emission factor of combined cooling, heating and power system per unit time = proportion of electricity, cooling and heating energy in total output energy x gas consumption x gas carbon emission factor / total amount of electricity, cooling and heating;

[0112] f) Carbon emission factor of grid electricity purchase per unit time is taken as the carbon emission factor per unit time of the upper substation according to the principle of proximity. When the carbon emission factor of the upper substation cannot be obtained, the carbon emission factor of the public Chinese provincial grid can be taken as the value;

[0113] g) Carbon flow density of cold and heat distribution station is taken as the carbon emission factor per unit time of the upper cold and heat production station according to the principle of proximity;

[0114] For the load node i in the load loop of the user side comprehensive energy network, the carbon emission value (carbon emission factor per unit time) caused by the consumption of unit energy is equal to the weighted value of the carbon flow density corresponding to all energy flows flowing into node i, that is,

[0115]

[0116] In the formula, the carbon flow density represents the carbon emission of unit energy transmitted by the nth loop flowing into node i, unit: kgCO2 / kW; represents the energy supply and consumption data of the nth loop flowing into node i;

[0117] Taking the energy supply node in the energy supply loop of the user side comprehensive energy network as the starting point, the carbon emission factor per unit time of each loop and each node in the network can be sequentially calculated according to the equality of the carbon flow density of the energy flow of all loops flowing out of node i and the carbon emission factor per unit time of the node;

[0118] Step five, constructing the carbon flow density matrix of each loop of the user side comprehensive energy network at time t, .The value of each element of the matrix is:

[0119]

[0120] Step six, the energy flow distribution matrix of each loop of the user side comprehensive energy network above ) and the network loop carbon flow density matrix (F) ) to obtain the Hadamard product , the network loop carbon flow distribution matrix (F) at time t, that is,

[0121] (Hadamard product)

[0122] Step seven, the measured value of the carbon emission responsibility factor of load node j in each load loop of the user side comprehensive energy network at time t is recorded as , unit: kgCO2 / kW, which is equal to the sum of the jth row elements of the network loop carbon flow distribution matrix (F), that is:

[0123]

[0124] Step eight, the actual value of the total carbon emission of the user is calculated according to the measured value of the carbon emission responsibility factor at time t and the total number of nodes, and is recorded as ,

[0125]

[0126] Compare with , if , the user is warned that the system carbon emission is about to exceed the long-time limit, and each load node in the network is ranked in descending order according to the total carbon emission responsibility factor and displayed to the user, and the user can select the load for cutting according to the actual situation;

[0127] If , the user is warned that the system carbon emission has exceeded the long-time limit, and the user can also select the load for cutting according to the actual situation; after the user selects the specified node i for cutting, the platform will update the actual carbon emission;

[0128] If , step nine is executed;

[0129] Step nine, day-ahead prediction is performed by using an autoregressive time series model to obtain the predicted data of energy supply and consumption of loop ij at time t, recorded as ,
