[0101] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0102] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0103] Reference Figure 1 As shown, a flowchart of a target detection model training method according to an embodiment of the present invention is shown. Figure 1 As shown, the target detection model training method can be used in electronic devices such as computers, mobile phones, tablet computers, servers, etc. The target detection model training method includes the following steps:

[0104] Step S101: Obtain wind power generation data, solar power generation data and oil field power consumption data, wherein the oil field power consumption data is the power consumption data of all power-consuming equipment in the oil field management system, and the oil field management system is used to manage the power transmission of all power-consuming equipment in the oil field.

[0105] In this embodiment, the oilfield management system is used to manage the power transmission of all electrical equipment in the oilfield; the oilfield power consumption data includes the power consumption data of all electrical equipment in the oilfield management system and the access or removal data of all electrical equipment; the total power generation includes wind power generation and solar power generation; the total power includes wind power generation, solar power generation, power in the energy storage device and power grid power.

[0106] Step S102: Obtaining total power generation according to the wind power generation data and the solar power generation data.

[0107] In this embodiment, the wind power generation data is obtained by the wind power generation system converting the mechanical energy generated by wind energy into electrical energy; the solar power generation data is obtained by the solar power generation system converting the voltage generated by light into electrical energy; the total power generation at the current moment can be obtained based on the wind power generation data and solar power generation data at the current moment.

[0108] Step S103: Obtaining predicted electricity consumption of the oil field according to the electricity consumption data of the oil field.

[0109] In this embodiment, the power consumption in the oilfield management system is a discontinuous function that changes with time. The predicted power consumption of the oilfield at the current moment can be roughly predicted based on the power consumption data of the oilfield at the previous moment.

[0110] Step S104: Compare the total power generation with the predicted power consumption of the oil field.

[0111] In this embodiment, after obtaining the total power generation at the current moment and the predicted power consumption of the oil field at the current moment, the relationship between the two can be compared to perform intelligent coordinated control of the total power.

[0112] Step S105: When the total power generation is not less than the predicted power consumption of the oil field, according to the formula: total power generation - predicted power consumption of the oil field = remaining total power generation, the power equal to the predicted power consumption of the oil field in the total power generation is transmitted to the oil field management system, and the remaining total power generation is transmitted to the energy storage device.

[0113] In this embodiment, when the total power generation is not less than the predicted power consumption of the oil field, the total power generation is used to power the electrical equipment in the oil field management system, and the remaining part of the total power generation after being used for power supply is stored in the energy storage device, shortening the power transmission process and reducing energy loss.

[0114] Specifically, when the total power generation is greater than the predicted power consumption of the oil field, it means that the total power generation is sufficient to power the power consumption equipment in the oil field management system. At this time, the power equal to the predicted power consumption of the oil field is directly taken from the total power generation to power the power consumption equipment in the oil field management system, and the remaining part of the total power generation after power supply is stored in the energy storage device; when the total power generation is equal to the predicted power consumption of the oil field, the entire total power generation is directly transmitted to the oil field management system to power the power consumption equipment in the oil field management system. The method provided in this embodiment is adopted to directly power the power consumption equipment in the oil field by controlling the power generation generated by wind power generation and solar power generation, thereby reducing the energy loss caused by storing the power generation before power supply, and improving the energy utilization rate.

[0115] In a preferred embodiment, the method further comprises the following steps:

[0116] Step S106: When the total power generation is less than the predicted power consumption of the oil field, according to the formula: predicted power consumption of the oil field - total power generation = remaining power demand, the total power generation is transmitted to the oil field management system, and power equal to the remaining power demand is transmitted from the energy storage device to the oil field management system.

[0117] In this embodiment, when the total power generation is less than the predicted power consumption of the oil field, it means that the total power generation is insufficient to meet the power consumption of the power equipment in the oil field management system. At this time, the total power generation is transmitted to the oil field management system, and a part of it needs to be taken out from the energy storage device to meet the power consumption of the power equipment in the oil field management system.

[0118] In a preferred embodiment, the method further comprises the following steps:

[0119] Step S107: Acquire the stored electricity, where the stored electricity is the electricity stored in the energy storage device.

[0120] In this embodiment, the amount of electricity that can be stored in the energy storage device is not unlimited. If the total power generation continues to be greater than the predicted power consumption of the oil field, the remaining total power generation will continue to be stored in the energy storage device, and the energy storage device will be fully charged. Therefore, in order to prevent the energy storage device from storing too much electricity, it is necessary to monitor the amount of electricity stored in the energy storage device in real time.

[0121] Step S108: When the stored electricity is greater than a first threshold, the remaining total power generation is transmitted to the power grid, and the first threshold is used to indicate that the electricity stored in the energy storage device is fully charged.

[0122] In this embodiment, the energy storage device is connected to the power grid. When the amount of electricity stored in the energy storage device reaches a first threshold, it means that the energy storage device is full and can no longer store electricity, so the remaining total power generation after the energy storage device is full is transmitted to the power grid.

[0123] In a preferred embodiment, the method further comprises the following steps:

[0124] Step S109: acquiring stored electricity, where the stored electricity is the electricity stored in the energy storage device.

[0125] In this embodiment, the amount of electricity stored in the energy storage device is not unlimited, and therefore cannot be used indefinitely. If the total power generation continues to be less than the predicted power consumption of the oil field, the power in the energy storage device will continue to be used in the oil field, and the power in the energy storage device will be used up. In order to prevent the energy storage device from storing too little electricity, resulting in insufficient electricity required by the oil field management system, it is necessary to monitor the amount of electricity stored in the energy storage device in real time.

[0126] Step S110: When the stored power is less than a second threshold, the total power generation is transmitted to the energy storage device, and the power grid is controlled to supply power to the oilfield management system. The second threshold is used to indicate that the power stored in the energy storage device is insufficient.

[0127] In this embodiment, the oilfield management system is connected to the power grid. When the power stored in the energy storage device is less than the second threshold, it means that the power stored in the energy storage device is insufficient and cannot continue to be used by the oilfield management system, so the power grid is controlled to supply power to the oilfield management system.

[0128] In a preferred embodiment, the step S103 comprises the following steps:

[0129] Step S1031: According to the oil field electricity consumption data, the total electricity consumption of the oil field at time T-1 is obtained, where time T-1 is the previous time of the current time.

[0130] In this embodiment, it is necessary to predict the electricity consumption of the oil field at the current moment, and the prediction method adopted is to predict by the total electricity consumption of the oil field at the previous moment, so it is necessary to obtain the total electricity consumption of the oil field at the previous moment.

[0131] Step S1032: monitor whether any electrical equipment is connected or removed from the oilfield management system at the time T-1.

[0132] In this embodiment, since the power consumption in the oil field management system is a discontinuous function that changes with time, there is an impulse response when a power device is connected or removed. We need to monitor whether there is a power device connected or removed at the previous moment, so as to accurately predict the predicted power consumption of the oil field at the current moment.

[0133] Step S1033: When no power-consuming equipment is connected and removed at the time T-1, the total power consumption of the oilfield at the time T-1 is determined as the predicted power consumption of the oilfield at the time T, where the time T is the current time.

[0134] In this embodiment, when it is monitored that no electrical equipment was connected and no electrical equipment was removed from the oilfield management system at the previous moment, it means that the predicted electricity consumption of the oilfield at the current moment should be consistent with the total electricity consumption of the oilfield at the previous moment. Therefore, the total electricity consumption of the oilfield at the previous moment is determined as the predicted electricity consumption of the oilfield at the current moment.

[0135] In a preferred embodiment, the step S103 comprises the following steps:

[0136] Step S1034: According to the oil field electricity consumption data, the total electricity consumption of the oil field at time T-1 is obtained, where time T-1 is the previous time of the current time.

[0137] In this embodiment, it is necessary to predict the electricity consumption of the oil field at the current moment, and the prediction method adopted is to predict by the total electricity consumption of the oil field at the previous moment, so it is necessary to obtain the total electricity consumption of the oil field at the previous moment.

[0138] Step S1035: monitor whether any electrical equipment is connected or removed from the oilfield management system at the time T-1.

[0139] In this embodiment, since the power consumption in the oil field management system is a discontinuous function that changes with time, there is an impulse response when a power device is connected or removed. We need to monitor whether there is a power device connected or removed at the previous moment, so as to accurately predict the predicted power consumption of the oil field at the current moment.

[0140] Step S1036: When an electric device is connected to the oilfield management system at time T-1, the energy storage device supplies power to the oilfield management system at time T-1.

[0141] In this embodiment, when it is monitored that an electrical device is connected at the previous moment, the amount of electricity required by the oilfield management system will increase at the moment of connection. Since it is difficult to determine the power consumption of the newly connected electrical device, the amount of electricity in the oilfield management system may be insufficient at this time. Therefore, it is necessary to switch to powering the oilfield management system through the energy storage device.

[0142] Step S1037: The sum of the total power consumption of the oil field at time T-1 and the power consumption of the power-consuming equipment connected at time T-1 is determined as the predicted power consumption of the oil field at time T, where time T is the current time.

[0143] In this embodiment, when it is detected that an electric device is connected at the last moment, the oilfield management system has been powered by the energy storage device at the last moment, and it is in time to predict the predicted power consumption of the oilfield at the current moment. The electric device connected at the last moment will continue to consume power before being removed, so the sum of the total power consumption of the oilfield at the last moment and the power consumption of the electric device connected at the last moment is used as the predicted power consumption of the oilfield at the current moment.

[0144] In a preferred embodiment, the method further comprises the following steps:

[0145] Step S111: installing an overload protector in the circuit of the oilfield management system, wherein the overload protector is used to perform overload protection on electrical equipment and electrical lines in the oilfield management system.

[0146] In this embodiment, in order to prevent excessive electricity in the oilfield management system from causing power overload of electrical equipment and electrical lines in the oilfield, an overload protector is installed in the circuit of the oilfield management system.

[0147] Step S112: defining an electrical device whose power is greater than a power threshold as a high-power electrical device.

[0148] In this embodiment, since there are many high-power electrical equipment in the oil field, when these high-power electrical equipment are removed from the oil field management system, directly supplying power with the total power generation will cause the circuit to be fully loaded, which is very dangerous. The impact caused by the removal of low-power electrical equipment is often negligible compared to the removal of these high-power electrical equipment. Therefore, it is necessary to set a power threshold to distinguish between high-power electrical equipment and low-power electrical equipment. At this time, when electrical equipment with power greater than the power threshold is removed from the oil field management system, directly supplying power with the total power generation will cause the circuit to be fully loaded; and the impact caused by the removal of electrical equipment with power less than the power threshold on the circuit can be ignored.

[0149] Step S113: installing an infrared sensor at the switch of the high-power electrical equipment, and turning on the infrared sensor and the high-power electrical equipment at the same time.

[0150] In this embodiment, in order to monitor whether the high-power electrical equipment is removed, an infrared sensor is installed at the switch of the high-power electrical equipment, and the infrared sensor and the high-power electrical equipment are turned on at the same time. After the infrared sensor is turned on, the switch temperature of the high-power electrical equipment is continuously measured to continuously monitor whether an object touches the switch.

[0151] Step S114: the infrared sensor is used to detect whether an object touches the switch. When it is detected that an object touches the switch, it is determined that the high-power electrical device is removed.

[0152] In this embodiment, when the infrared sensor detects that an object touches the switch, that is, when the switch temperature of the high-power electrical device suddenly increases or decreases, it is determined that the high-power electrical device has been removed.

[0153] In a preferred embodiment, the step S103 comprises the following steps:

[0154] Step S1038: According to the oil field electricity consumption data, the total electricity consumption of the oil field at time T-1 is obtained, where time T-1 is the previous time of the current time.

[0155] In this embodiment, it is necessary to predict the electricity consumption of the oil field at the current moment, and the prediction method adopted is to predict by the total electricity consumption of the oil field at the previous moment, so it is necessary to obtain the total electricity consumption of the oil field at the previous moment.

[0156] Step S1039: monitor the oilfield management system through the infrared sensor to see whether the high-power electrical equipment is removed at time T-1.

[0157] In this embodiment, in order to monitor whether the high-power electrical equipment is removed, an infrared sensor is installed at the switch of the high-power electrical equipment, and the infrared sensor and the high-power electrical equipment are turned on at the same time. After the infrared sensor is turned on, the switch temperature of the high-power electrical equipment is continuously measured to continuously monitor whether an object touches the switch.

[0158] Step S10310: When the high-power electrical equipment is removed from the oilfield management system at time T-1, the difference between the total power consumption of the oilfield at time T-1 and the power consumption of the high-power electrical equipment removed at time T-1 is determined as the predicted power consumption of the oilfield at time T, where time T is the current time.

[0159] In this embodiment, when the infrared sensor detects that an object touches the switch, that is, when the switch temperature of the high-power electrical device suddenly rises or falls, it is determined that the high-power electrical device has been removed. If it is determined that the high-power electrical device has been removed at the previous moment, the high-power electrical device will not consume electricity at the current moment, but because the high-power electrical device was still working at the previous moment, it still consumed electricity. Therefore, the difference between the total electricity consumption of the oil field at the previous moment and the electricity consumption of the high-power electrical device removed at the previous moment is determined as the predicted electricity consumption of the oil field at the current moment.

[0160] In a preferred embodiment, the step S103 comprises the following steps:

[0161] Step S10311: installing an overload protector in the circuit of the oilfield management system, wherein the overload protector is used to perform overload protection on electrical equipment and electrical routes in the oilfield management system.

[0162] In this embodiment, since there are many high-power electrical equipment in the oil field, when these high-power electrical equipment are removed from the oil field management system, directly supplying power with the generated power will cause the circuit to be fully loaded, which is very dangerous. Therefore, in order to prevent the power overload of the electrical equipment and electrical lines in the oil field caused by excessive power in the oil field management system, an overload protector is installed in the circuit of the oil field management system.

[0163] Step S10312: define an electrical device whose power is greater than a power threshold as a high-power electrical device.

[0164] In this embodiment, since there are many high-power electrical equipment in the oil field, when these high-power electrical equipment are removed from the oil field management system, directly supplying power with the total power generation will cause the circuit to be fully loaded, which is very dangerous. The impact caused by the removal of low-power electrical equipment is often negligible compared to the removal of these high-power electrical equipment. Therefore, it is necessary to set a power threshold to distinguish between high-power electrical equipment and low-power electrical equipment. At this time, when electrical equipment with power greater than the power threshold is removed from the oil field management system, directly supplying power with the total power generation will cause the circuit to be fully loaded; and the impact caused by the removal of electrical equipment with power less than the power threshold on the circuit can be ignored.

[0165] Step S10313: Install an infrared sensor at the switch of the high-power electrical device, and turn on the infrared sensor and the high-power electrical device at the same time.

[0166] In this embodiment, in order to monitor whether the high-power electrical equipment is removed, an infrared sensor is installed at the switch of the high-power electrical equipment, and the infrared sensor and the high-power electrical equipment are turned on at the same time. After the infrared sensor is turned on, the switch temperature of the high-power electrical equipment is continuously measured to continuously monitor whether an object touches the switch.

[0167] Step S10314: The infrared sensor is used to detect whether an object touches the switch. When it is detected that an object touches the switch, it is determined that the high-power electrical device is removed.

[0168] In this embodiment, when the infrared sensor detects that an object touches the switch, that is, when the switch temperature of the high-power electrical device suddenly increases or decreases, it is determined that the high-power electrical device has been removed.

[0169] Step S10315: According to the oil field electricity consumption data, the total electricity consumption of the oil field at time T-1 is obtained, where time T-1 is the previous time of the current time.

[0170] In this embodiment, it is necessary to predict the electricity consumption of the oil field at the current moment, and the prediction method adopted is to predict by the total electricity consumption of the oil field at the previous moment, so it is necessary to obtain the total electricity consumption of the oil field at the previous moment.

[0171] Step S10316: monitor the oilfield management system to see whether the high-power electrical equipment is removed and whether the electrical equipment is connected at time T-1.

[0172] In this embodiment, since the power consumption in the oilfield management system is a discontinuous function that changes with time, there is an impulse response when a power device is connected or removed. We need to monitor whether a power device was connected or removed at the previous moment. At the same time, the removal of high-power power devices has the greatest impact. Therefore, it is necessary to monitor whether a high-power power device was removed from the oilfield management system at the previous moment, so as to accurately predict the predicted power consumption of the oilfield at the current moment.

[0173] Step S10317: When the high-power electrical equipment is removed from the oilfield management system at time T-1 and electrical equipment is connected, the energy storage device is used to supply power to the oilfield management system at time T-1.

[0174] In this embodiment, at the last moment, a high-power electrical device was removed and at the same time, a power device was connected. At this time, it is difficult to determine whether the power required by the oilfield management system is increasing or decreasing. Therefore, at the last moment, the oilfield management system is powered by the energy storage device.

[0175] Step S10318: According to the formula: Total power consumption of the oil field (T-1) -Power consumption of high-power electrical equipment (T-1) +Power consumption of newly connected electrical equipment (T-1) = Forecasted electricity consumption of oil fields (T) .

[0176] In this embodiment, the predicted power consumption of the oil field at the current moment is obtained through calculation based on the total power consumption of the oil field at the last moment, the power consumption of the high-power electrical equipment removed at the last moment, and the power consumption of the newly connected electrical equipment at the last moment.

[0177] Step S10319: Substitute the oil field predicted electricity consumption in the formula (T) , determined as the predicted electricity consumption of the oil field at time T, where time T is the current time.

[0178] In this embodiment, according to the above formula, the predicted electricity consumption of the oil field at the current moment can be accurately obtained.

[0179] In a preferred embodiment, the method further comprises the following steps:

[0180] Step S115: installing an overload protector in the circuit of the oilfield management system, wherein the overload protector is used to prevent the excess power consumption in the oilfield management system compared with the predicted power consumption of the oilfield from affecting the power consumption equipment and electrical routes in the oilfield management system when the high-power power consumption equipment is removed.

[0181] In this embodiment, since there are many high-power electrical equipment in the oil field, when these high-power electrical equipment are removed from the oil field management system, directly supplying power with the generated power will cause the circuit to be fully loaded, which is very dangerous. Therefore, in order to prevent the power overload of the electrical equipment and electrical lines in the oil field caused by excessive power in the oil field management system, an overload protector is installed in the circuit of the oil field management system.

Figure 3 A schematic diagram of a microgrid model of a distributed energy resource collaborative control method proposed in an embodiment of the present application is shown in FIG. Figure 2 and Figure 3 As shown:

[0183] The wind power generation system converts the mechanical energy generated by wind into electrical energy, inverts the converted electrical energy through an AC / AC converter and transmits it to the EMS master station, which records the wind power generation data;

[0184] The EMS master station analyzes the wind power generation data to obtain the current wind power generation X t ;

[0185] The solar power generation system converts the voltage generated by sunlight into electrical energy, inverts the converted electrical energy through a DC / AC converter, and transmits it to the EMS master station, which records the solar power generation data;

[0186] The EMS master station analyzes the solar power generation data to obtain the current solar power generation Y t ;

[0187] The oilfield management system sends the oilfield power consumption data to the EMS master station, and the energy storage device sends the stored power data to the EMS master station;

[0188] The EMS master station analyzes the oil field power consumption data and predicts the oil field power consumption Z at the current moment t ;

[0189] The EMS master station analyzes the stored electricity in the energy storage device, the predicted electricity consumption of the oil field and the total power generation data, and conducts intelligent coordination of the total electricity:

[0190] When X t +Y t ≥Z t When the EMS master station will Z t The total power generation is transmitted to the oilfield management system, and the remaining total power generation X t +Y t -Z t Transmit to energy storage device for storage;

[0191] When X t +Y t <Z t When the EMS master station will X t +Y t The total power generation is transmitted to the oil field management system, which controls the energy storage device to t -X t -Y t The power is transmitted to the oilfield management system;

[0192] Among them, X t , Y t and Z t It is constantly changing with the passage of time.

[0193] The energy storage EMS in the energy storage device monitors the stored power in the energy storage device in real time and sends the power storage data to the EMS master station.

[0194] In order to prevent the oilfield management system from using too much electricity and insufficient power in the energy storage device, the oilfield management system is connected to the power grid; when the power stored in the energy storage device is lower than the threshold value K1, the EMS master station controls the power grid to supply power to the oilfield management system, where K1 is the threshold value when the power stored in the energy storage device is insufficient;

[0195] In order to prevent excessive power storage in the energy storage device, the energy storage device is connected to the power grid; when the stored power in the energy storage device reaches the threshold value K2, the EMS master station transmits the remaining total power generation to the power grid, where K2 is the threshold value when the energy storage device is fully charged.

[0196] Among them, the oilfield management system is used to manage the transmission of electricity in the oilfield; the oilfield electricity consumption data includes the electricity consumption data of all electrical equipment in the oilfield management system and the access or removal data of all electrical equipment; the total electricity includes wind power generation, solar power generation, electricity in energy storage devices and power grid electricity; the total power generation includes wind power generation and solar power generation.

[0197] Specifically, for example:

[0198] The wind power generation system transmits the current wind power generation of 500kw to the EMS master station;

[0199] The solar power generation system transmits the current solar power generation of 1000kw to the EMS main station;

[0200] The oilfield management system detects that no power-consuming equipment was connected or removed at the last moment, and a high-power power-consuming equipment is removed at the current moment. At this time, the power consumption of the oilfield at the last moment was 1550kw, and the power consumption of the high-power power-consuming equipment was 100kw. The oilfield power consumption data is sent to the EMS master station;

[0201] The energy storage device sends the current power storage data to the EMS master station. At this time, the energy storage device stores 20kwh of power.

[0202] Among them, the threshold K1 is set to 0.05kwh, and the threshold K2 is set to 50kwh;

[0203] The EMS master station analyzes the oilfield power consumption data and predicts that the current oilfield power consumption is 1550kw. Therefore, the EMS master station transmits the current total power generation of 1500kw to the oilfield management system and controls the energy storage device to transmit 50kw of power to the oilfield management system.

[0204] The wind power generation system transmits the next moment's wind power generation of 499kw to the EMS master station;

[0205] The solar power generation system transmits the next moment's solar power generation of 1001kw to the EMS main station;

[0206] The oilfield management system detects that no power-consuming equipment is connected or removed at the next moment. At this moment, the power consumption of the oilfield is 1500kw, and the power consumption data of the oilfield is sent to the EMS master station;

[0207] Since high-power electrical equipment has been removed at the current moment, the EMS master station analyzes the oil field power consumption data at the next moment and predicts that the oil field power consumption at the next moment will be 1450kw. Therefore, the EMS master station transmits the total power generation of 1450kw at the next moment to the oil field management system, and controls the remaining total power generation of 50kw to be transmitted to the energy storage device for storage.
