In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0100] The user-side integrated energy system consists of a coupled heating system, energy storage batteries, distributed photovoltaics, distributed wind turbines, air conditioners, V2G charging piles, smart appliances and multi-energy collaborative processors. Its system architecture is as follows: Figure 1 As shown. The user-side integrated energy system comprehensively utilizes city electricity, wind, light, gas, and tap water, and provides users with integrated energy supply services of electricity, heat, cold, and hot water through efficient conversion. Among them, the coupled heating system includes three heat-generating devices: gas boilers, electric boilers, and air source heat pumps. The multi-energy collaborative processor can communicate with the power grid cloud master station upward, report the adjustable capacity to the master station regularly, and receive adjustment instructions from the power grid cloud master station; the multi-energy collaborative processor can communicate with each device in the user-side integrated energy system downward, collect user load information, and formulate demand response strategies to control the optimal operation of each device in the user-side integrated energy system.

[0101] The first embodiment of the present invention relates to a method for responding to demand of a user-side integrated energy system, which can be implemented by a multi-energy co-processor of the user-side integrated energy system, such as Figure 2 As shown, the specific steps include:

[0102] Step 1: Calculate the adjustable capacity of each device in the current user-side integrated energy system, including: the adjustable capacity of the coupled heating system, the adjustable capacity of the energy storage system, the adjustable capacity of the charging pile, the adjustable capacity of the smart appliance, and the adjustable capacity of the air conditioner.

[0103] In this step, the multi-energy co-processor calculates the adjustable capacity of each core device / system in the current user-side integrated energy system within each specified time step, which are the adjustable capacity of the coupled heating system P K1 , Energy storage system adjustable capacity P K2 , Charging pile can adjust capacity P K3 , Smart appliances can adjust capacity P K4 , and adjustable air conditioning capacity P K5 .

[0104] like Figure 3 As shown, the coupled heating system can adjust the capacity P K1 The calculation process includes:

[0105] Determine whether the gas boiler in the coupled heating system is running at full power. If the gas boiler in the coupled heating system is running at full power, the coupled heating system can adjust the capacity P K1 is zero;

[0106] If the gas boiler in the coupled heating system is not operating at full power, it is determined whether the remaining heating capacity of the gas boiler in the coupled heating system can replace the heating capacity of the heat pump and the electric boiler, that is, the potential of the gas boiler to replace the heating capacity of the heat pump and the electric boiler is determined by the following formula.

[0107]

[0108] in, Q hp is the heat supply of the heat pump at the current moment, Q eb is the heating capacity of the electric boiler at the current moment, Q gb,max is the rated heating capacity of the gas boiler, Q gb is the heating capacity of the gas boiler at the current moment. When , it means that the remaining heat supply of the gas boiler in the coupled heating system can replace the heat supply of the heat pump and the electric boiler. At this time, the adjustable capacity of the coupled heating system is the current operating power of the heat pump. P hp Current operating power of Hedian boiler P eb The sum of P k1 = P hp + P eb ;like , then proceed to the next step of judgment.

[0109] It is determined whether the surplus heat supply of the gas boiler in the coupled heating system can replace the heat supply of the electric boiler, that is, the potential of the gas boiler to replace only the electric boiler is determined by the following formula.

[0110]

[0111] when When the excess heat of the gas boiler in the coupled heating system can replace the heat of the electric boiler, the coupled heating system can adjust the capacity P k1 = P eb ; Otherwise, the coupled heating system has adjustable capacity and adjustable capacity P k1 Produced by electric boilers ( Q gb,max - Q gb ) The corresponding operating power when the heat of hot water is P eb,run .

[0112] like Figure 4As shown, the energy storage system can adjust the capacity P K2 The calculation process includes:

[0113] 1) Determine whether the energy storage system is in a charging state; if the energy storage system is in a charging state, detect the total power generation of renewable energy (including photovoltaic and wind turbine) in the detection system, and determine whether the total power generation of renewable energy is less than the power generation setting value; if the total power generation of renewable energy is less than the power generation setting value, further determine whether the SOC of the energy storage battery is greater than the first SOC setting value SOC up1 , if the SOC of the energy storage battery is less than or equal to the first SOC setting value SOC up1 , then the energy storage system can adjust the capacity P K2 If the total power generation of the renewable energy is greater than or equal to the power generation setting value, or the SOC of the energy storage battery is greater than the first SOC setting value SOC up1 , then the energy storage system can adjust the capacity P K2 is zero.

[0114] 2) If the energy storage system is not in a charging state, determine whether the energy storage system is in a discharging state; if the energy storage system is not in a discharging state, further determine whether the SOC of the energy storage battery is greater than a second SOC setting value SOC up2 , if the SOC of the energy storage battery is greater than the second SOC setting value SOC up2 , then the energy storage system can adjust the capacity P K2 is the energy storage discharge power; if the energy storage system is in a discharging state, or the SOC of the energy storage battery is less than or equal to the second SOC setting value SOC up2 , then the energy storage system can adjust the capacity P K2 is zero.

[0115] like Figure 5 As shown, the charging pile can adjust the capacity P K3 The calculation process includes:

[0116] 1) Determine whether the charging pile is in operation, that is, whether the charging pile is in charging state. If the charging pile is in charging state, the charging pile can adjust the capacity. P K3 for n 充 times the operating power of the charging pile, of which, n 充 The ratio of the operating power that the charging pile is allowed to reduce to the total operating power of the charging pile.

[0117] 2) If the charging pile is not in operation, further determine whether the charging pile has an electric facility connected and the electric facility has the capacity to provide reverse charging. If the charging pile has an electric facility connected and the electric facility has the capacity to provide reverse charging, the charging pile can adjust the capacity. P K3 is the reverse charging power of the electric facility; if the charging pile has no connected electric facility, or the charging pile has connected electric facility but the electric facility has no capacity for reverse charging, the charging pile can adjust the capacity P K3 is zero.

[0118] like Figure 6 As shown, smart appliances can adjust capacity P K4 The calculation process is as follows:

[0119] Determine whether the smart appliance is in operation. If the smart appliance is in operation, the smart appliance can adjust the capacity P K4 for n 电器 times the operating power of smart appliances, among which, n 电器 The ratio of the operating power that the smart appliance can adjust downward to the total operating power of the smart appliance; if the smart appliance is not in operation, the adjustable capacity of the smart appliance P K4 is zero.

[0120] like Figure 7 As shown, the air conditioner can adjust the capacity P K5 The calculation process is as follows:

[0121] Determine whether the air conditioner is in operation; if the air conditioner is in cooling operation, the air conditioner can adjust the capacity P K5 The air conditioner reduces its operating power after the set temperature is increased by 1-2°C or the air conditioner wind speed is reduced; if the air conditioner is in the heating operation state, the air conditioner can adjust the capacity P K5 The air conditioner reduces its operating power by lowering the set temperature by 1-2°C or lowering the air conditioner wind speed; if the air conditioner is not in operation, the air conditioner can adjust the capacity P K5 is zero.

[0122] Step 2: determine the demand response operation mode according to the user's wishes, and report the adjustable capacity corresponding to the demand response operation mode according to the determined demand response operation mode and the adjustable capacity of each device.

[0123] Step 3: Receive grid regulation instructions and operate the user-side integrated energy system according to the determined demand response operation mode.

[0124] In this implementation, the user-side integrated energy system has two demand response operation modes, namely, ordinary demand response operation mode and deep participation demand response operation mode. Users can choose the operation mode of the user-side integrated energy system according to their own participation willingness. The user-side integrated energy system communicates with the power grid cloud master station through the multi-energy co-processor, reports the adjustable capacity according to the specified time step, and accepts the demand response adjustment instructions from the power grid cloud master station, changes the system operation strategy to adjust the operation status of each device, and responds to the power grid demand. Figure 8 As shown, specifically including:

[0125] First, determine whether the user chooses to participate in the demand response operation mode. If the user does not choose to participate in the demand response operation mode, report to the master station that the current adjustable capacity is zero; if the user chooses to participate in the demand response operation mode, further determine whether the user chooses to deeply participate in the demand response operation mode.

[0126] If the user does not select the deep participation demand response operation mode, it means that the user has selected the ordinary demand response operation mode. At this time, the adjustable capacity of the coupled heating system is calculated. P K1 The energy storage system can adjust the capacity P K2 The sum of the sum is taken as the current adjustable capacity and reported to the master station. Next, it is determined whether a grid regulation instruction is received. If a grid regulation instruction is received, the system is switched to the normal demand response operation mode and the operation strategy is adjusted. It is operated in the normal demand response operation mode until the response time is over. If no grid regulation instruction is received, it ends directly.

[0127] The operation strategy of the common demand response operation mode is as follows: Fig. 9 As shown, specifically:

[0128] 1) Determine the adjustable capacity of the coupled heating system P K1 Is it greater than zero, if the coupled heating system can adjust the capacity P K1 is greater than zero, the coupled heating system can adjust the capacity P K1 Adding Responded Capacity P x , that is,P x =P x +P K1 The gas boiler in the coupled heating system is adjusted to full power, and the remaining heat load gap is met by the heat pump and the electric boiler in turn; if the coupled heating system can adjust the capacity P K1 If it is not greater than zero, proceed to the next step;

[0129] 2) Determine the adjustable capacity of the energy storage system P K2 Is it greater than zero? If the energy storage system can adjust the capacity P K2 Not greater than zero, go directly to the next step; if the energy storage system can adjust the capacity P K2 is greater than zero, the energy storage system can adjust the capacity P K2 Adding Responded Capacity P x , that is, P x =P x +P K2 , and determine the response capacity P x Is it less than the grid demand? If the capacity has been responded to P x If it is greater than or equal to the grid demand, it ends directly; if the response capacity has been P x If the energy storage battery of the energy storage system is less than the power grid demand, it is determined whether the energy storage battery of the energy storage system is in a charging state. If the energy storage battery of the energy storage system is in a charging state, the energy storage system stops charging; if the energy storage battery of the energy storage system is not in a charging state, the energy storage system is adjusted to discharge at full power.

[0130] If the user chooses to participate in the demand response operation mode in depth, the adjustable capacity of the coupled heating system is calculated P K1 , Energy storage system adjustable capacity P K2 , Charging pile can adjust capacity P K3 , Smart appliances can adjust capacity P K4 And the air conditioning adjustable capacity P K5The sum is taken as the current adjustable capacity and reported to the master station. Next, it is determined whether a grid regulation instruction is received. If a grid regulation instruction is received, the system is switched to the deep participation demand response operation mode and the operation strategy is adjusted. The system is operated in the deep participation demand response operation mode until the response time is over. If no grid regulation instruction is received, the system ends directly.

If the capacity has been responded to P x If it is greater than or equal to the grid demand, it ends directly; if the response capacity has been P xIf the power demand is less than the power grid demand, it is determined whether the energy storage battery of the energy storage system is in a charging state. If the energy storage battery of the energy storage system is in a charging state, the energy storage system stops charging; if the energy storage battery of the energy storage system is not in a charging state, the energy storage system is adjusted to full power discharge and proceeds to the next step;

[0134] Determine the adjustable capacity of the charging pile P K3 Is it greater than zero? If the charging pile can adjust the capacity P K3 If the charging pile can adjust the capacity, then go to the next step.
