[0002] At present, the energy system is transforming towards clean, low-carbon, safe and efficient, and green electricity, as a key form of clean energy, is becoming increasingly important.

[0003] However, current cross-region green electricity dispatching is still in the pilot exploration stage and has many problems. On the one hand, cross-region green electricity dispatching involves a variety of complex and interrelated factors, such as the randomness and volatility of green electricity itself, and the problems of insufficient capacity and peak shaving capability of power export channels. In existing research on cross-region electricity dispatching, the main focus is on mechanism research, and there is a lack of model design for cross-region green electricity dispatching and quantitative analysis of its dispatching conditions, making it difficult to fully and accurately reflect the various complex factors of cross-region green electricity dispatching.

[0049] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0050] Example 1

[0051] Figure 1 This is a schematic diagram of the main flow of a method for constructing a cross-regional green energy dispatch coupling model according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method for constructing the cross-regional green energy dispatch coupling model in this embodiment of the present invention includes the following steps S101 to S103.

[0052] Step S101: Set the characteristic quantities of the cross-regional green electricity dispatch coupling model based on the system dynamics model.

[0053] Step S102: Set the coupling relationship between the feature quantities of the cross-regional green electricity dispatch coupling model according to multiple green electricity settlement methods to obtain multiple cross-regional green electricity dispatch coupling models;

[0054] In step S103, the green electricity sending data of the cross-region green electricity dispatching coupling model is calculated based on the cross-region green electricity dispatching coupling model, and the target green electricity settlement mode and the target cross-region green electricity dispatching coupling model are filtered according to the green electricity sending data.

[0055] It can be understood that the system dynamics model is a computer simulation method for studying the dynamic behavior of a complex system. It simulates the change process of the system over time by establishing the coupling relationship between the characteristic quantities in the system, and describes how a system operates and changes with mathematical and computer models. Specifically, the coupling relationship between the characteristic quantities includes the causal relationship and the feedback loop. The causal relationship indicates that the change of one variable will cause the change of another variable. In the model, these causal relationships are usually represented by arrows, and the direction of the arrow indicates the direction of the causal action. The feedback loop is a closed loop composed of a series of causal relationships. The feedback loop can be divided into positive feedback loop and negative feedback loop. The positive feedback loop will enhance the trend of a certain change in the system, and the negative feedback loop will weaken the trend of a certain change in the system. For example: the green electricity supply-demand ratio of the sending end→(+) the green electricity demand of the sending end→(-) the green electricity supply-demand ratio of the sending end. It indicates that the increase of the green electricity supply-demand ratio of the sending end will lead to oversupply, in which case the green electricity price of the sending end will decrease, so that the green electricity demand of the sending end will increase, which will drive the green electricity price of the sending end to rise, and reduce the green electricity supply-demand ratio of the sending end. The green electricity supply-demand of the sending end reaches a steady state.

[0056] Specifically, in the embodiment and some embodiments of the application, the cross-region green electricity dispatching coupling model includes a sending end green electronic system and a receiving end green electronic system, and the characteristic quantities of the cross-region green electricity dispatching coupling model include the characteristic quantities of the sending end green electronic system, the characteristic quantities of the receiving end green electronic system, and the characteristic quantities common to the sending end green electronic system and the receiving end green electronic system. It can be understood that the characteristic quantity is the basic element in the cross-region green electricity dispatching coupling model, which is various factors of system operation and change, including state variables, rate variables, auxiliary variables and constants; the state variable describes the state of the system at a certain time, for example, the total social electricity consumption of the sending end; the rate variable represents the rate of change of the state variable over time, for example, the utilization rate of the power transmission channel; the auxiliary variable is used for auxiliary calculation, such as green electricity settlement price; and the constant is, for example, the upper and lower limits of the green electricity on-grid price.

[0057] Further, in the embodiment and some embodiments of the application, the characteristic quantities of the sending end green electronic system include the green electricity on-grid price of the sending end, the green electricity production and operation cost of the sending end, and the characteristic quantities common to the sending end green electronic system and the receiving end green electronic system include the green electricity settlement price, the green electricity cost price, the average transaction price of green certificates in the last trading period, and the marginal carbon emission reduction cost of thermal power and the carbon trading cost of thermal power plants.

[0058] Further, in the embodiment and some embodiments of the application, the green electricity settlement mode includes a first green electricity settlement mode, a second green electricity settlement mode, and a third green electricity settlement mode.

[0059] The first green electricity settlement mode is to settle according to a green electricity settlement price obtained by smoothing the green electricity on-grid price of the sending end.

[0060] Specifically, in some embodiments of the application, the green electricity settlement price is obtained by smoothing the "sending end green electricity price variation" and then applying a "safety range" limit. The final value of the price will not be lower than 0.15 or higher than 0.85. If the smoothing result is between 0.15 and 0.85, it is used as is; if it is too high (>0.85), it is pressed to 0.85, and if it is too low (<0.15), it is raised to 0.15.

[0061] Specifically, in the simulation software Vensim, it is set as:

[0062] Green electricity settlement price = IFTHENELSE(SMOOTH3I (sending end green electricity price variation, 12, 0.4171) > 0.85, 0.85, IFTHENELSE(SMOOTH3I (sending end green electricity price variation, 12, 0.4171) < 0.15, 0.15, SMOOTH3I (sending end green electricity price variation, 12, 0.4171))).

[0063] The SMOOTH3I function is a smoothing function in Vensim, which is used to smooth the variable, (12 represents that the average time is 12 months, and 0.4171 is the initial price of green electricity. The conditional function IFTHENELSE (condition 1, A, B) in Vensim means that if condition 1 is met, the value is A, otherwise the value is B, and it can be nested.

[0064] The second green electricity settlement mode is to settle according to a green electricity settlement price obtained by measuring the green electricity cost price and the average transaction price of green certificates in the last trading period.

[0065] Specifically, in the simulation software Vensim, it is set as:

[0066] Green electricity settlement price = green electricity cost price + average transaction price of green certificates in the last trading period (e.g., month).

[0067] The green electricity cost price is the sending end green electricity production and operation cost, which is executed according to the coal benchmark price.

[0068] The third green electricity settlement mode is to settle according to a green electricity settlement price obtained by measuring the green electricity cost price and the marginal carbon emission reduction cost of thermal power.

[0069] Specifically, in the simulation software Vensim, it is set as follows:

[0070] Green electricity settlement price = green electricity cost price + marginal carbon emission reduction cost of thermal power.

[0071] The marginal carbon emission reduction cost of thermal power is obtained by derivation on the carbon trading cost of the thermal power plant.

[0072] It can be understood that the sending-end green electronic system and the receiving-end green electronic system are relative, and one subsystem receiving green electricity is the receiving-end green electronic system, and outputting green electricity is the sending-end green electronic system. Further, in the embodiment and some embodiments of the application, the sending-receiving relationship of the sending-end green electronic system and the receiving-end green electronic system in the cross-region green electricity dispatching coupling model includes one-to-one power transmission, one-to-many power transmission, many-to-one power transmission and many-to-many power transmission.

[0073] Further, in the embodiment and some embodiments of the application, the characteristic quantity of the sending-end green electronic system further includes the sending-end total social electricity consumption, the sending-end expected green electricity demand, the green electricity transaction volume proportion, the sending-end total social electricity growth rate, the sending-end total social electricity initial value, the sending-end green electricity starting construction installed capacity, the annual average utilization hours of wind power and photovoltaic power generation, the sending-end green electricity completed construction installed capacity, the sending-end green electricity under-construction installed capacity, the sending-end green electricity installed capacity, the sending-end green electricity power generation, the monthly average utilization hours of wind power and photovoltaic power generation, the sending-end green electricity sending capacity, and the sending-end non-water renewable energy consumption responsibility weight; the characteristic quantity of the receiving-end green electronic system includes the receiving-end actual receivable green electricity quantity and the receiving-end green electricity outsourcing demand quantity; the characteristic quantity common to the sending-end green electronic system and the receiving-end green electronic system further includes the physical constraint from the sending-end to the receiving-end, the transmission quantity proportion of the receiving-end demand, the sending-end to receiving-end transmission line capacity, the sending-end to receiving-end transmission line utilization efficiency, the sending-end to receiving-end transmission line loss rate, and the sending-end to receiving-end green electricity transmission quantity.

[0074] Further, in the embodiment and some embodiments of the application, the coupling relationship between the characteristic variables of the sending-end green electronic system and the receiving-end green electronic system includes the following eight coupling relationships.

[0075] The first coupling relationship: according to the sending-end total social electricity consumption and the green electricity settlement price, the sending-end expected green electricity demand is calculated; the sending-end total social electricity consumption is obtained according to the sending-end total social electricity growth rate and the sending-end total social electricity initial value.

[0076] Specifically, in the simulation software Vensim, it is set as follows:

[0077] The sending-end expected green electricity demand = the sending-end total social electricity consumption x 0.1945 x (the green electricity settlement price / 0.4171)^(-0.25).

[0078] The sending-end total social electricity consumption = INTEG (the sending-end total social electricity growth rate, 84.23).

[0079] Wherein, 0.1945 represents the proportion of green electricity transaction volume; A^B represents The operation of the INTEG function is mainly to integrate a variable, describe the change process of the state variable in the system, and the change of the total social electricity consumption of the sending end is determined by the electricity consumption growth rate, and 84.23 is the initial value of the total social electricity consumption of the sending end; A^B represents Operation, the ratio of the changed electricity price and the initial electricity price is raised to the power of-0.25, reflecting the reverse influence of the change of green electricity price on the demand of green electricity of the sending end.

[0080] The second coupling relationship: according to the predicted green electricity demand of the sending end and the green electricity settlement price, the starting construction installed capacity of the green electricity of the sending end is calculated;

[0081] Specifically, in the simulation software Vensim, it is set as:

[0082] The starting construction installed capacity of the green electricity of the sending end = the predicted green electricity demand of the sending end / (1772*the green electricity settlement price).

[0083] Wherein, 1772 represents the annual average utilization hours of wind power and photovoltaic power generation.

[0084] The third coupling relationship: according to the starting construction installed capacity of the green electricity of the sending end, the completed construction installed capacity of the green electricity of the sending end is calculated;

[0085] Specifically, in the simulation software Vensim, it is set as:

[0086] The completed construction installed capacity of the green electricity of the sending end = DELAYFIXED (the starting construction installed capacity of the green electricity of the sending end, 12, 0).

[0087] Wherein, DELAYFIXED is a fixed delay function, the initial value of the completed construction installed capacity of the green electricity of the sending end is 0, and it takes 12 months to construct the installed capacity of the green electricity of the sending end, and the completed construction installed capacity of the green electricity of the sending end is calculated after 12 months.

[0088] The fourth coupling relationship: according to the starting construction installed capacity of the green electricity of the sending end and the completed construction installed capacity of the green electricity of the sending end, the under-construction installed capacity of the green electricity of the sending end is calculated;

[0089] Specifically, in the simulation software Vensim, it is set as:

[0090] The under-construction installed capacity of the green electricity of the sending end = INTEG (the starting construction installed capacity of the green electricity of the sending end-the completed construction installed capacity of the green electricity of the sending end, 0).

[0091] Wherein, 0 represents the initial value of the under-construction installed capacity of the green electricity of the sending end.

[0092] The fifth coupling relationship: according to the under-construction installed capacity of the green electricity of the sending end, the installed capacity of the green electricity of the sending end is calculated;

[0093] Specifically, in the simulation software Vensim, it is set as:

[0094] The sending end green power installed capacity = INTEG (the sending end green power under construction installed capacity, 0.5)

[0095] Wherein, 0.5 represents the initial value of the sending end green power installed capacity.

[0096] The sixth coupling relationship: according to the sending end green power installed capacity, the sending end green power generation capacity is calculated;

[0097] Specifically, in the simulation software Vensim, it is set as:

[0098] The sending end green power generation capacity = the sending end green power installed capacity x 147.67

[0099] Wherein, 147.67 represents the monthly average utilization hours of wind power and photovoltaic power generation, and 147.67 is obtained by 1772 / 12 of the annual average utilization hours of wind power and photovoltaic power generation.

[0100] The seventh coupling relationship, according to the sending end green power generation capacity and the sending end total social power consumption, the sending end green power transmission capacity is calculated.

[0101] Specifically, in the simulation software Vensim, it is set as:

[0102] The sending end green power transmission capacity = the sending end green power generation capacity - the sending end non-water renewable energy power consumption responsibility weight x the sending end total social power consumption.

[0103] The eighth coupling relationship: according to the physical constraints from the sending end to the receiving end and the receiving end green power purchase demand, the actual green power that the receiving end can receive is calculated; The physical constraints from the sending end to the receiving end include: the transmission channel capacity from the sending end to the receiving end, the transmission channel utilization rate

[0104] Specifically, in the simulation software Vensim, it is set as:

[0105] The actual green power that the receiving end can receive = IFTHENELSE (the receiving end green power purchase demand x the transmission capacity accounts for the proportion of the receiving end demand / (1-the sending end to the receiving end transmission line loss rate) > the sending end to the receiving end transmission line capacity x the sending end to the receiving end transmission line utilization efficiency x 8760, the sending end to the receiving end transmission line capacity x the sending end to the receiving end transmission line utilization efficiency x 8760, the receiving end green power purchase demand x the transmission capacity accounts for the proportion of the receiving end demand / (1-the sending end to the receiving end transmission line loss rate)).

[0106] The green electricity actually received by the receiving end depends on two values: the first value is the electricity amount that needs to be delivered after considering line loss, i.e., the green electricity outsourcing demand of the receiving end multiplied by the proportion of electricity transmission to the demand of the receiving end, and then divided by 1 minus the line loss rate of the transmission line from the sending end to the receiving end; and the second value is the maximum transmission electricity amount of the transmission line in a year, i.e., the capacity of the transmission line from the sending end to the receiving end multiplied by the utilization efficiency and then multiplied by the annual electricity transmission time of 8760 hours. If the first value is greater than the second value, the actual received electricity amount is equal to the maximum transmission electricity amount of the transmission line; otherwise, the actual received electricity amount is equal to the first value.

[0107] The ninth coupling relationship: according to the green electricity sending capacity of the sending end and the green electricity actually received by the receiving end, the green electricity amount sent from the sending end to the receiving end is calculated.

[0108] Specifically, in the simulation software Vensim, the following is set:

[0109] The green electricity amount sent from the sending end to the receiving end = IFTHENELSE (the green electricity sending capacity of the sending end x 0.7 < the green electricity actually received by the receiving end, the green electricity sending capacity of the sending end x 0.7, the green electricity actually received by the receiving end).

[0110] In order to ensure that the actual sent electricity amount does not exceed 70% of the green electricity sending capacity of the sending end, and if the planned transmission amount is within 70% of the sending capacity, the planned transmission is performed.

[0111] Further, in the embodiment and some embodiments of the application, the green electricity sending data of the cross-region green electricity dispatching coupling models is calculated based on the cross-region green electricity dispatching coupling model, and the target green electricity settlement mode and the target cross-region green electricity dispatching coupling model are selected according to the green electricity sending data, including:

[0112] (1) The cross-region green electricity dispatching coupling models are loaded in the simulation environment respectively, and the simulation parameters are set.

[0113] (2) The cross-region green electricity dispatching coupling models are run in the simulation environment to obtain the green electricity amount sent from the sending end to the receiving end of the cross-region green electricity dispatching coupling model corresponding to the green electricity price settlement mode.

[0114] (3) The green electricity price settlement mode and the cross-region green electricity dispatching coupling model with the maximum green electricity amount sent from the sending end to the receiving end are selected as the target green electricity settlement mode and the target cross-region green electricity dispatching coupling model.

[0115] Specifically, in the embodiment and some embodiments of the application, the simulation parameters are the starting time, the ending time, the time step and the like. In VensimPLE, the simulation parameters are configured in the model simulation window. The time step of the model is set to 1 month, the starting time is the first month, and the ending time is the 96th month. The simulation model is simulated by using the simulation running of VensimPLE, and the output result is observed. According to the simulation result, the behavior and possible trend of the system are analyzed. The green power quantities of the sending end and the receiving end under three green power price settlement modes are obtained, and are compared, so that the optimal target green power settlement mode between the sending end and the receiving end and the target cross-region green power dispatching coupling model are obtained.

[0116] The embodiment of the application introduces the system dynamics theory, constructs a coupling dynamics model containing a sending end green power system and a receiving end green power system, accurately depicts the dynamic feedback mechanism of green power transmission and transaction in different regions, sets three types of green power settlement mechanisms by establishing a green power settlement function relationship, solves the system based on the fitting of model parameters with real data, simulates multiple scenarios, quantitatively compares the variation law of the sending end green power under different settlement modes, and finally outputs the optimal green power settlement scheme and power grid dispatching strategy of the green power sending amount. The method of the embodiment of the application not only realizes accurate simulation and scheme optimization of the cross-region green power dispatching dynamic process, but also effectively solves the green power environmental right and interest attribution problem through settlement mechanism innovation, and provides data support for regional power grid low-carbon dispatching.
