Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the present invention provides a distributed resource aggregation regulation communication network measurement system, as shown in fig. 1, the system includes: the system comprises a resource aggregation regulation platform, a network management system, a plurality of resource edge aggregation devices and a plurality of distributed resources; the resource aggregation regulation and control platform is connected with a plurality of distributed resources through a plurality of resource edge aggregation devices to form a service channel, and the service channel is used for resource regulation and control; the network management system is connected with a plurality of resource edge aggregation devices to form a management channel, and the management channel is used for network state measurement.
The resource aggregation regulation and control platform can be a system of a power grid marketing department, and also can be a platform of a large-scale third party aggregator, and the platform is directly connected with a power grid regulation and control main station. The resource edge aggregation device can be a small third party aggregator platform (for example, a building is an aggregator), or can be an edge aggregation device of partial resources (for example, an industrial park is an aggregator, a refrigerator is connected by using one resource edge aggregation device, and an air conditioner is connected by using one resource edge device). Specifically, when the service channel works, the resource aggregation regulation and control platform issues a regulation and control instruction to the resource edge aggregation device, the resource edge aggregation device decomposes the regulation and control instruction into a distributed resource output control instruction, and the distributed resource executes the output control instruction. The distributed resource reports the resource state information to the resource edge aggregation device, and the resource edge aggregation device forms external standard output characteristics according to the resource state information and reports the characteristics to the resource aggregation regulation platform.
The network management system is connected with the resource edge aggregation device, wherein all the resource edge aggregation devices can be connected, and part of the resource edge aggregation devices can be connected according to actual needs, and state information of the device itself reported by the resource edge aggregation device is received. Meanwhile, the network management system can realize the on-line management of the connected resource edge aggregation device, such as configuration management, security management, state monitoring, fault alarm management, user management and the like. The network management system realizes the measurement of the network state through the received state information. In addition, it should be noted that, in special states such as emergency state, system upgrade, etc., the network management system can also carry out service function or management function transplanting with the resource aggregation regulation platform, thus enhancing the robustness of service and management.
At present, the power grid regulation master station can only acquire the adjustable capability of resource reporting, but does not consider the influence of network performance. For example, if a certain aggregator reports that the load of 10MW can be reduced, then the resource can be selected for use when the main power grid station regulates and controls the resource to do regulation and control business (peak regulation, frequency modulation and the like). However, in practice, the communication network of the resource is unstable or has larger time delay, so that the time delay requirement of peak shaving can be met, but the time delay requirement of frequency modulation service cannot be met. The adjustable capacity of the resource is comprehensively evaluated through the network performance state measured by the network management system. For example, how many MW can participate in the frequency modulation service, and how many MW can participate in the peak shaving service, so that the potential of the distributed resource to participate in the small time scale regulation can be accurately evaluated.
According to the distributed resource aggregation regulation communication network measurement system provided by the embodiment of the invention, the network management system and the resource edge aggregation device are arranged on the basis of the resource aggregation regulation platform, the resource edge aggregation device and the distributed resource to form the management channel, so that various network state measurement can be supported, and the service channel can comprehensively evaluate the adjustable capacity of the resource based on the network state measurement result, thereby accurately evaluating the potential of the distributed resource to participate in small time scale regulation.
In an alternative embodiment, the network management system needs to synchronize time with the resource aggregation regulation platform and the resource edge aggregation device before performing network state measurement. Wherein, as shown in fig. 2, the plurality of resource edge aggregation devices include a plurality of high-precision resource edge aggregation devices and a plurality of low-precision resource edge aggregation devices; the resource aggregation regulation and control platform, the network management system and the high-precision resource edge aggregation devices comprise a satellite time synchronization module, wherein the satellite time synchronization module is used for satellite time synchronization; the master resource edge aggregation device and the slave edge aggregation devices adopt master-slave network time synchronization, and the master-slave network time synchronization and the satellite time synchronization are carried out simultaneously.
Specifically, the high-precision resource edge aggregation device refers to a resource edge aggregation device which participates in scenes with higher time precision requirements such as frequency modulation service, spot market and the like, and the low-precision resource edge aggregation device participates in scenes with lower time precision requirements such as demand response, peak shaving and the like. Before the distributed resource is accessed, whether the distributed resource participates in small-scale regulation such as frequency modulation or not needs to be determined, if so, an accessed resource edge aggregation device can be set as a high-precision resource edge aggregation device, and if not, the accessed resource edge aggregation device can be set as a low-precision resource edge aggregation device.
For the high-precision resource edge aggregation device, the same satellite time synchronization module can be installed with a resource aggregation regulation and control platform and a network management system, the satellite time synchronization module can be a GPS satellite time synchronization module, a GLONASS (GLOBAL NAVIGATION SATELLITE SYSTEM, global satellite navigation system) satellite time synchronization module or a Beidou satellite time synchronization module, and the satellite time synchronization module can synchronize satellite time signals into a local digital clock. The resource aggregation regulation platform and the satellite time setting module in the network management system are installed in the internal computer, server and other mediums. It should be noted that, because there is a time error between different satellite time synchronization modules, such as GPS and beidou, the same satellite time synchronization module installed in the high-precision resource edge aggregation device, the resource aggregation regulation platform and the network management system can improve the time synchronization accuracy.
For the low-precision resource edge aggregation device, one device can be selected as a main resource edge aggregation device, a satellite time synchronization module is arranged in the main resource edge aggregation device, and other low-precision resource edge aggregation devices can be used as slave resource edge aggregation devices to perform time synchronization with the main resource edge aggregation device in a time synchronization mode of NTP (Network Time Protocol ) and PTP (Precision Time Protocol, precision time protocol). Thereby achieving network time synchronization between low-precision resource edge aggregation devices. It should be noted that the satellite time synchronization module set in the main resource edge aggregation device may be the same as the satellite time synchronization module installed in the high-precision resource edge aggregation device.
In this embodiment, by adopting the satellite time synchronization and the network time synchronization method at the same time, high-precision time synchronization of part of devices in the communication network is realized, and the devices adopting network time synchronization in the communication network can also obtain synchronization precision close to the satellite time synchronization.
In an alternative embodiment, a two-channel network measurement may be implemented using a network management system. The network management system is used for collecting information of a plurality of resource edge aggregation devices and transmission information of network measurement data to obtain a first network state of a management channel; the network management system is also used for acquiring a second network state of the service channel, which is obtained by the resource aggregation regulation and control platform according to the information of the resource edge aggregation devices and the transmission information of the regulation and control service data, and matching the second network state with the first network state.
Specifically, as shown in fig. 3, when the second network state measurement, that is, the in-band measurement of the service channel is performed, the resource aggregation regulation and control platform and the resource edge aggregation device perform the regulation and control service information interaction through the extended 1376.1 protocol, and the resource aggregation regulation and control platform collects the equipment state information of the resource edge aggregation device and the transmission information of the regulation and control service data through the extended field. And the resource aggregation regulation and control platform analyzes the acquired information data to obtain a second network state of the service channel. The equipment state information comprises CPU utilization rate, memory utilization rate, disk utilization rate, starting-up operation time and the like of the resource edge aggregation device. The transmission information of the regulation service data comprises the network port connection state of the corresponding network port, the number of network port receiving and transmitting data packets, the number of network port receiving and transmitting data packet bytes and network time delay. After the resource aggregation regulation platform receives the information, firstly cleaning abnormal data, and then analyzing and processing the cleaned data and visually displaying, wherein the analyzing and processing can be to set a series of thresholds for network time delay, and the time delay is rated (low, medium, high, ultrahigh, etc.) through the thresholds, and different alarm levels are given for high-level and ultrahigh-level. The network port congestion degree index can also be given by combining two indexes of the number of network port transmitting and receiving data packets and the byte number of the network port transmitting and receiving data packets. In addition, the prediction can be performed by adopting a related technology according to the cleaned data.
As shown in fig. 3, when the first network state measurement, that is, the management channel in-band measurement is performed, the network management system performs network management information interaction with the resource edge aggregation device through the MQTT protocol, and the network management system periodically collects the device state information of the resource edge aggregation device and the transmission information of network measurement data. The network management system analyzes the acquired information data to obtain a first network state of the management channel. The transmission information of the network measurement data specifically includes a network port connection state of the network port corresponding to the network measurement data, the number of network port receiving and transmitting data packets, the number of network port receiving and transmitting data packet bytes, a network delay, etc., and an analysis processing process of the network measurement data can refer to an analysis processing process of the second network state and is not described herein again.
After the network management system measures and obtains the first network state and receives the second network state sent by the resource aggregation regulation and control platform, the first network state and the second network state are matched according to the identity information of the resource edge aggregation devices, the first network state and the second network state corresponding to each resource edge aggregation device obtained through matching are compared and analyzed, abnormal, missing and repeated data are cleaned, the two-channel network state is respectively presented according to the cleaned data, and network state fault diagnosis is assisted.
In an alternative embodiment, as shown in fig. 4 and fig. 5, the network management system is further configured to interpolate the second network state, and map the interpolation result with the first network state and perform complementary calculation on the network state, so as to obtain a global network state. Specifically, when interpolation is performed on the second network state, firstly, the interpolation number between each acquisition time node is determined, and the interpolation number is comprehensively determined according to the measurement frequency of the management channel and the network global state measurement frequency to be finally generated. After the interpolation number is determined, generating the second network state of interpolation measurement by curve fitting and other methods according to the second network state of actual measurement. For example, the second network state is measured once for 15 minutes, while the first network state is measured once for 1 minute, and finally it is intended to present one measurement data every 1 minute. Then the second network state may be set to have an interpolation every 30 seconds for better interpolation.
After interpolation is carried out on the second network state, the second network state is mapped with the first network state according to the identity tag and the time tag. And according to the formula t=αt s +βt m CalculatingNetwork global state. Where t is the global state of the network for a time slot, t s T is the interpolated second network state for the time slot m Is the first network state for that slot. The alpha and beta are discount coefficients between 0 and 1, and can be comprehensively determined according to factors such as a time synchronization method adopted by a service channel and a management channel, a time delay measurement method adopted by the management channel, the similarity degree of the management channel and the service channel and the like. For example, the time synchronization accuracy of the service channel is very high, the network repeatability of the service channel and the management channel is relatively high (for example, the network is a wired network which is not passed through a wireless public network, and the network is all walked), then the measurement result of the service channel is considered to have relatively high credibility, the value of alpha can be close to 1, and the value of beta can be close to 0. If the time synchronization precision of the management channel is far higher than that of the service channel, and the network repeatability of the service channel and the management channel is higher, the measurement result of the management channel is considered to have higher credibility, and can take a value of beta between 0.7 and 1.
In accordance with an embodiment of the present invention, there is provided a distributed resource aggregate regulating communication network measurement method embodiment, it being noted that the steps illustrated in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order other than that illustrated herein.
The embodiment provides a measuring method of a distributed resource aggregation regulation communication network, which is applied to a distributed resource aggregation regulation system, wherein the distributed resource aggregation regulation system comprises a resource aggregation regulation platform, a plurality of resource edge aggregation devices and a plurality of distributed resources; the resource aggregation regulation and control platform is connected with a plurality of distributed resources through a plurality of resource edge aggregation devices to form a service channel, and the measuring method can be used for the network management system of the embodiment. Fig. 6 is a flowchart of a method for measuring a distributed resource aggregation regulatory communication network according to an embodiment of the present invention, as shown in fig. 6, the flowchart includes the steps of:

Specifically, the network management system may implement the measurement of the first network state through communication with the resource edge aggregation device to which it is connected. For example, the network management system and the resource edge aggregation device perform network management information interaction through the MQTT protocol, and the network management system periodically collects equipment state information of the resource edge aggregation device and transmission information of network measurement data. The network management system analyzes the acquired information data to obtain a first network state. The equipment state information comprises CPU utilization rate, memory utilization rate, disk utilization rate, starting-up operation time and the like of the resource edge aggregation device. The transmission information of the network measurement data specifically comprises a network port connection state of the network port corresponding to the network port, the number of network port receiving and transmitting data packets, the number of network port receiving and transmitting data packet bytes, network time delay and other resource aggregation regulation and control platforms, after receiving the information, the abnormal data are cleaned, then the cleaned data are analyzed and processed and visually displayed, the analysis and processing can be to set a series of thresholds for the network time delay, and different alarm levels are given to high-grade and ultra-high-grade through the thresholds. The network port congestion degree index can also be given by combining two indexes of the number of network port transmitting and receiving data packets and the byte number of the network port transmitting and receiving data packets. In addition, the prediction can be performed by adopting a related technology according to the cleaned data.

Specifically, the resource aggregation regulation and control platform and the resource edge aggregation device perform regulation and control service information interaction through an extended 1376.1 protocol, and the resource aggregation regulation and control platform collects equipment state information of the resource edge aggregation device and transmission information of regulation and control service data through an extended field. And the resource aggregation regulation and control platform analyzes the acquired information data to obtain a second network state of the service channel. The equipment state information comprises CPU utilization rate, memory utilization rate, disk utilization rate, starting-up operation time and the like of the resource edge aggregation device. The transmission information of the regulation service data comprises the network port connection state of the corresponding network port, the number of network port receiving and transmitting data packets, the number of network port receiving and transmitting data packet bytes and network time delay. After the resource aggregation regulation platform receives the information, firstly cleaning abnormal data, and then analyzing and processing the cleaned data and visually displaying, wherein the analyzing and processing can be to set a series of thresholds for network time delay, and the time delay is rated (low, medium, high, ultrahigh, etc.) through the thresholds, and different alarm levels are given for high-level and ultrahigh-level. The network port congestion degree index can also be given by combining two indexes of the number of network port transmitting and receiving data packets and the byte number of the network port transmitting and receiving data packets. In addition, the prediction can be performed by adopting a related technology according to the cleaned data. And after the second network state is obtained, the resource aggregation regulation and control platform sends the second network state to the network management system.

The method for measuring the distributed resource aggregation regulation communication network provided by the embodiment of the invention firstly performs time synchronization with a resource aggregation regulation platform and a plurality of resource edge aggregation devices, then acquires first network information and second network information, and calculates the global state of the network by adopting a mapping complementation method. The measuring method can realize high-precision time synchronization and fine granularity monitoring of the network, and can effectively support the virtual power plant to participate in multi-time scale regulation and control services such as power grid peak regulation, frequency modulation and the like.
The embodiment provides a measuring method of a distributed resource aggregation regulation communication network, which is applied to a distributed resource aggregation regulation system, wherein the distributed resource aggregation regulation system comprises a resource aggregation regulation platform, a plurality of resource edge aggregation devices and a plurality of distributed resources; the resource aggregation regulation and control platform is connected with a plurality of distributed resources through a plurality of resource edge aggregation devices to form a service channel, and the measuring method can be used for the network management system of the embodiment. Fig. 1 is a flowchart of a method for measuring a distributed resource aggregation regulatory communication network according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
Step S201, time synchronization is carried out with a resource aggregation regulation and control platform and a plurality of resource edge aggregation devices.

Before the distributed resource is accessed, whether the distributed resource participates in small-scale regulation such as frequency modulation or not needs to be determined, if so, an accessed resource edge aggregation device can be set as a high-precision resource edge aggregation device, and if not, the accessed resource edge aggregation device can be set as a low-precision resource edge aggregation device.
Specifically, the step S201 includes:
step S2011, performing satellite time synchronization with a resource aggregation regulation platform and a plurality of high-precision resource edge aggregation devices; specifically, satellite time synchronization can be realized by installing a satellite time synchronization module. The satellite time synchronization module may be a GPS satellite time synchronization module, a GLONASS (GLOBAL NAVIGATION SATELLITE SYSTEM, global satellite navigation system) satellite time synchronization module, or a beidou satellite time synchronization module, which may synchronize satellite time signals into a local digital clock. The resource aggregation regulation platform and the satellite time setting module in the network management system are installed in the internal computer, server and other mediums. It should be noted that, because there is a time error between different satellite time synchronization modules, such as GPS and beidou, the same satellite time synchronization module can be installed in the high-precision resource edge aggregation device, the resource aggregation regulation and control platform and the network management system, so as to improve time synchronization accuracy.
In step S2012, master-slave network time synchronization and satellite time synchronization are simultaneously performed between the plurality of low-precision resource edge aggregation devices. For the low-precision resource edge aggregation device, one device can be selected as a main resource edge aggregation device, a satellite time synchronization module is arranged in the main resource edge aggregation device, other low-precision resource edge aggregation devices can be used as slave resource edge aggregation devices to synchronize time with the main resource edge aggregation device in a time synchronization mode of NTP (Network Time Protocol ) and PTP (Precision Time Protocol, precision time protocol).

Step S203, a second network state of the service channel, which is obtained by the resource aggregation regulation platform according to the information of the plurality of resource edge aggregation devices and the transmission information of the regulation service data, is obtained. Please refer to step S103 in the embodiment shown in fig. 1 in detail, which is not described herein.
Step S204, the first network state and the second network state are matched according to the identity information of the resource edge aggregation device, and a matching result is obtained; and diagnosing network state faults according to the matching result. Specifically, after the network management system measures and obtains the first network state and receives the second network state sent by the resource aggregation regulation platform, the first network state and the second network state are matched according to the identity information of the resource edge aggregation devices, the first network state and the second network state corresponding to each resource edge aggregation device obtained through matching are compared and analyzed, abnormal, missing and repeated data are cleaned, the two-channel network state is respectively presented according to the cleaned data, and network state fault diagnosis is assisted.
Step S205, mapping the first network state and the second network state and performing complementary calculation on the network state to obtain a network global state.
Specifically, the step S2051 includes:
step S2051, judging whether the acquisition frequency of the second network state meets the preset requirement; specifically, the preset requirement may be determined according to the measurement frequency of the first network state and the measurement frequency of the network global state that is ultimately required to be generated.
Step S2052, when the preset requirement is not met, performing interpolation processing on the second network state to obtain an interpolation result; specifically, when the acquisition frequency of the second network state does not meet the preset requirement, determining the interpolation number between each acquisition time node of the second network state according to the preset requirement. After the interpolation number is determined, generating the second network state of interpolation measurement by using methods such as curve fitting and the like based on the second network state of actual measurement. When the acquisition frequency of the second network state meets the preset requirement, no processing is needed, and subsequent processing can be directly performed.
Step S2053, mapping the interpolation result and the first network state according to the identity information of the resource edge aggregation device to obtain a mapping result; specifically, through the mapping process, a first network state and a second network state corresponding to each resource edge aggregation device may be determined.
Step S2054, based on the mapping result, performing network state complementary calculation according to the discount coefficient corresponding to the first network state and the second network state, so as to obtain a network global state. Specifically, the network global state may be calculated according to the following formula:
t＝αt s +βt m
network in which t is a time slotThe global state, t s T is the interpolated second network state for the time slot m Is the first network state for that slot. Alpha, beta are discount coefficients between 0 and 1.
