[0002] Smart home electricity consumption is a key tool for providing high-quality energy and enhancing customer service engagement in the future. With the advancement of re-electrification and the continued rise in end-user electricity consumption, the integration of smart home electricity consumption with core businesses is becoming increasingly stronger. The development of smart home electricity consumption is showing clear trends towards digitalization, platformization, and marketization, and its business value is gradually becoming apparent. Furthermore, by building new business models and service systems for smart home electricity consumption, it is possible to aggregate households' adjustable load resources and deeply participate in grid interaction services, paving a new path for safer grid operation, leaner management, more targeted investment, and higher-quality services.

[0003] However, there is currently a lack of unified interoperability testing methods and test environments for the interaction between residential users and the power grid. Most home appliance companies currently build their own home appliance cloud platforms, and each home appliance company has different technical architectures, technical solutions and standards. The industry lacks common interoperability technical standards and is unable to accurately assess the ability of load-side resources to interact with the power grid, which restricts the scale of interaction between residential loads and the power grid. Summary of the Invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a method for testing the interoperability of small and micro loads of residents with the power grid. By building a test and verification environment for the interoperability of small and micro loads of residents with the power grid, a test system for the interoperability of small and micro loads of residents with the power grid is established to evaluate the interactive capabilities of residential load resources with the power grid. The present invention also provides a test system for the interoperability of small and micro loads of residents with the power grid.

[0005] Technical solution: The present invention provides a method for testing the interoperability between residential micro-loads and power grids, comprising the following steps:

[0006] 1) Conduct interconnection tests between small and micro load devices on the residential side and the grid side;

[0007] 2) Determine whether the interoperability test is qualified. If the handshake is successful and a response is received, the interoperability test is qualified. Obtain the communication protocol used by the small and micro load devices on the resident side, and select the test case of the corresponding protocol to perform the protocol consistency test process;

[0008] 3) Determine whether the protocol consistency test process is qualified. If all protocol consistency test items are passed, enter the interoperability test process in each scenario; 4) Conduct a comprehensive evaluation based on the results of the interoperability test in each scenario. If it meets the set rules, the interoperability test is determined to be qualified.

[0009] Further, before the interconnection test of the small and micro load equipment on the resident side and the power grid side is carried out, the power grid side is simulated through the interoperation test system, and the interoperation test of the small and micro load on the resident side and the power grid is carried out.

[0010] Further, the interoperation test selects a first interactive networking mode and / or a second interactive networking mode, wherein the first interactive networking mode is WIFI networking, and the smart household appliances with WIFI are connected to the interoperation test system through the home router for networking, and the ordinary household appliances in the smart household appliance inventory are connected to the interoperation test system through the WIFI Internet of Things socket; the second interactive networking mode is HPLC networking, and the household appliances with the HPLC module are connected to the indoor smart gateway through the HPLC, the smart gateway directly communicates with the interoperation test system, and the ordinary household appliances in the smart household appliance inventory are connected to the interoperation test system through the HPLC Internet of Things socket.

[0011] Further, if the handshake cannot be performed, the interoperation test is directly determined to be unqualified, the test is stopped, and a test report is output.

[0012] Further, the protocol consistency test process comprises the following steps:

[0013] 2.1 Polling multiple protocol instructions are issued to the small and micro load equipment on the resident side which has established a connection, and the reply of the connected small and micro load equipment on the resident side is waited for;

[0014] 2.2 After receiving the reply of the connected small and micro load equipment on the resident side, the communication protocol used by the small and micro load equipment on the resident side is obtained, and the test case corresponding to the protocol is selected from the protocol test case library for consistency test.

[0015] Further, if each test item of the protocol consistency is not passed, the interoperation test result is directly determined to be unqualified, and a test report is output.

[0016] Further, the interoperation test under each scenario comprises:

[0017] The first scenario is the interoperation test of the power grid demand response service system and the demand response terminal, and the operation mode of the first scenario is that the power grid side directly inquires whether the user side participates in the demand response, if the user side agrees, the power grid side issues a command to the user side, based on the demand response target, an interruptible load strategy of reducing the load capacity is formulated, and the strategy that can be responded by the user includes electricity transfer, rigid control and flexible control.

[0018] The second scenario involves testing the interoperability of a demand response aggregation system and a demand response terminal. In this scenario, the load aggregator, acting as a demand response intermediary, queries adjustable loads on the user side within a specified area to determine whether to participate in demand response. If the user agrees, the load aggregator issues a command to the user. Based on the demand response target, an interruptible load reduction strategy is developed to reduce load capacity. The strategies that users can respond to include power shifting, rigid control, and flexible control.

[0019] The third scenario is the interoperability test between the power grid demand response service system, the demand response aggregation system and the demand response terminal. The operation method of the third scenario is: the power grid side issues commands to the load aggregators that can participate in the demand response, and formulates an interruptible load strategy for reducing the load capacity based on the demand response target. The strategies that users can respond to include power transfer, rigid control, and flexible control. The load aggregators who obtain the task decompose the task according to the adjustable potential of the user-side adjustable load in the specified area, and ask the user-side adjustable load in the specified area whether to participate in the demand response. If the user side agrees, the power grid side issues commands to the user side, and formulates an interruptible load strategy for reducing the load capacity based on the demand response target. The strategies that users can respond to include power transfer, rigid control, and flexible control.

[0020] Furthermore, a comprehensive evaluation is performed based on the results of the tests in each scenario, and the setting rules include the following steps:

[0021] 4.1 The total score of the test is set to U, Where W i is the weight coefficient of the test score of the i-th scenario, f i The interoperability test score for the i-th scenario is 100 points. The test score is directly given by the test system based on the test item results.

[0022] 4.2 The results of the interoperability test are judged by the weighted factor comparison method. There are two configurations of the weight coefficients of the test scores. Configuration 1 has a test score coefficient of 30%-35%-35% for each scenario, which is a balanced score. Configuration 2 has a test score coefficient of 20%-40%-40%, which is set by the tester. If the total score U>88, it is determined that the interoperability test between the residential micro-load and the power grid has passed. Furthermore, if the total score U>95, it is determined that the residential micro-load can fully participate in the grid interaction.

[0023] The present invention also provides a residential micro-load and power grid interoperability testing system, which includes an interconnection test module, a protocol test module, a protocol judgment module, and a scenario test and evaluation module;

[0024] The interconnection test module is used for interconnection test of small and micro load equipment on the resident side and the power grid side.

[0025] The protocol test module is used for judging whether the interconnection test is qualified, if the handshake is successful and the reply is received, the interconnection test is qualified, the communication protocol used by the small and micro load equipment on the resident side is acquired, and the test case corresponding to the protocol is selected to perform the protocol consistency test process.

[0026] The judgment protocol module is used for judging whether the protocol consistency test process is qualified, if all the test items of the protocol consistency pass, the interoperation test process under each scene is entered.

[0027] The evaluation module is used for comprehensive evaluation according to the results of the interoperation test under each scene, if the set rule is met, it is determined that the interoperation test is qualified.

[0031] Figure 1 is a flowchart of the present application;

[0032] Figure 2 is a schematic diagram of the interoperation test system architecture in the present application;

[0033] Figure 3 This is the WIFI networking method in the present invention. DETAILED DESCRIPTION

[0034] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] See also Figure 1 As shown, the present invention provides a method for testing the interoperability between residential micro-loads and power grids, comprising the following steps:

[0037] Before conducting the interconnection test, we first simulate the grid side by building an interoperability test system to conduct interoperability tests between small and micro loads on the residential side.

[0038] See also Figure 2 As shown, an interoperability test system is built to simulate the power grid side. The test system consists of a test bench, interoperability test software, local communication access, remote communication access, and a metering system. The device under test is connected to the interoperability test software through local networking to carry out interoperability testing. The interoperability test software can also be connected to a third-party cloud platform through remote communication to carry out interoperability testing. The test bench simulates a typical household energy usage scenario. The electrical appliances are all typical household smart devices with WIFI modules and can communicate in a local network. The test bench can measure the electricity of a single device, and the electricity meter's power data is sent to the interoperability test software.

[0039] The interoperability test selects the first interactive networking mode and / or the second interactive networking mode. The first interactive networking mode is WIFI networking. Smart home appliances with WIFI are connected to the interoperability test system through home routers. At the same time, ordinary home appliances in the smart home appliance inventory are connected to the interoperability test system through WIFI IoT sockets. The second interactive networking mode is HPLC networking. Home appliances with HPLC modules are connected to the indoor smart gateway through HPLC. The smart gateway directly communicates with the interoperability test system. Ordinary home appliances in the smart home appliance inventory are connected to the interoperability test system through HPLC IoT sockets.

[0040] See also Figure 3 As shown, the air-conditioning load in residential households is a high-energy-consuming appliance on the user side. Taking this as an example, the interoperability test system simulates the grid side, conducts interoperability tests on the air-conditioning in residential households and the grid side, and networks the equipment and the test system. New smart home appliances have WIFI communication functions, connect to the Internet through home routers, and send data to a third-party cloud platform. The interoperability test system interacts with the third-party cloud platform built by home appliance manufacturers; existing home appliances use WIFI IoT sockets, connect to the Internet through home routers, and send data to the interoperability test system.

[0041] 1) First, the small and micro load equipment on the resident side and the interconnection and interoperation test of the grid side are carried out. After the air conditioning load is connected to the interoperability test system, the corresponding parameter configuration is carried out in the device management of the interoperability test system, and the interconnection and interoperation test is automatically started;

[0042] 2) The interoperability test system sends a command to the air conditioning load to carry out the interconnection and interoperation test, judges whether the interconnection and interoperation test is qualified, if the handshake is successful and the message replied according to the requirements of the interoperability test system is received, the interconnection and interoperation test is qualified, if the handshake fails, it is judged that the interoperability test is unqualified, the interoperability test system directly stops the test and outputs the unqualified report; After the interconnection and interoperation test is qualified, according to the interoperability test system setting, the protocol consistency test process is automatically entered, the interoperability test system obtains the communication protocol used by the small and micro load equipment on the resident side, selects the test case corresponding to the protocol for the protocol consistency test process;

[0043] 2.1 The interoperability test system polls and issues multiple protocol instructions to the small and micro load equipment on the resident side, i.e. the air conditioning load in this embodiment, which has established a connection, and waits for the reply of the air conditioning load;

[0044] 2.2 After the interoperability test system receives the message reply of the air conditioning load, the communication protocol used by the small and micro load equipment on the resident side, i.e. the air conditioning load in this embodiment, is parsed, and the test case corresponding to the protocol is selected from the protocol test case library for consistency test.

[0045] 3) Judge whether the protocol consistency test process is qualified, if the protocol consistency test items are passed, enter the interoperability test process under each scene, if the protocol consistency test items are not passed, directly judge that the interoperability test result is unqualified, and output the test report;

[0046] At the same time, after the protocol consistency test process is qualified, the interoperability test process under each scene is carried out, the typical scene design is carried out according to the demand response information interaction, and the scene test is carried out. The scene test includes:

[0047] The first scene is the interoperability test of the demand response service system and the demand response terminal. The operation mode of the first scene is that the grid side directly inquires whether the user side participates in the demand response, if the user side agrees, the grid side issues a command to the user side, formulates an interruptible load strategy of reducing load capacity based on the demand response target, and the strategy that the user can respond to includes electricity transfer, rigid control and flexible control;

[0048] The second scenario involves testing the interoperability of a demand response aggregation system and a demand response terminal. The load aggregator, acting as a demand response intermediary, asks users within a specified area whether to participate in the demand response. If the user agrees, the load aggregator issues a command to the user, formulating an interruptible load reduction strategy based on the demand response target. The user can respond to various strategies, including power shifting, rigid control, and flexible control.

[0049] The third scenario is the interoperability test between the power grid demand response service system, the demand response aggregation system and the demand response terminal. The operation method of the third scenario is as follows: the power grid side issues commands to the load aggregators that can participate in the demand response, and formulates an interruptible load strategy for reducing the load capacity based on the demand response target. The strategies that users can respond to include power transfer, rigid control, and flexible control. The load aggregators that receive the tasks decompose the tasks according to the adjustable potential of the user-side adjustable loads in the specified area, and ask the user-side adjustable loads in the specified area whether to participate in the demand response. If the user agrees, the power grid side issues commands to the user side, and formulates an interruptible load strategy for reducing the load capacity based on the demand response target. The strategies that users can respond to include power transfer, rigid control, and flexible control.

[0050] The interoperability test system queries the registration information of the air-conditioning load in this embodiment and checks the supported adjustment methods. The air-conditioning load can support flexible adjustment. The interoperability test system formulates and signs a DR contract based on the equipment information and test requirements, and enters the interoperability test scenario. At this time, the electricity meter that separately measures the air-conditioning load is turned on, and the minute-frozen power data is uploaded to the interoperability test system. In each scenario test, the system will select the corresponding test case for interoperability testing according to the test requirements. The grid side or load aggregator simulated in the scenario obtains the DR event information set in the system and issues control instructions to the air-conditioning load according to the signed DR contract data. The control instructions include response start time, response end time, target load reduction, reduction method, etc., to achieve load reduction of the air-conditioning equipment.

[0051] 4) Perform a comprehensive evaluation based on the results of the three scenario tests. If the results meet the set rules, the interoperability test is considered qualified and a test report is output. If only one scenario passes the test, the interoperability test is directly considered unqualified. The set rules include the following steps:

[0052] 4.1 The total score of the test is set to U, Where W i is the weight coefficient of the test score of the i-th scenario, f iThe interoperation test score of the ith scene is that the interoperation test full score of each scene is 100 points, a deduction system is adopted, the test score is directly given by the test system according to the test item result, the interoperation test system evaluates whether the air conditioner load completes the demand response according to the requirement according to the real-time power and the power change according to the power minute freezing data sent on the electric energy meter, the score is given by the system after the demand response event test items in this scene are completed, the full score is 100 points, and the incomplete ones are deducted according to the rules;

[0053] 4.2 The result of the interoperation test is judged by a weighted factor comparison method, and the weight coefficients of the test scores are configured in two ways. The test score coefficients of each scene in the first configuration are 30%-35%-35%, which belongs to balanced score, and the test score coefficients of each scene in the second configuration are 20%-40%-40%, which is set by the test personnel. If the total score U>88, it is determined that the residential small and micro load and the power grid interoperation test are qualified, further, if the total score U>95, it is determined that the residential small and micro load can completely participate in the power grid interaction;

[0054] The interoperation test of the power grid demand response service system and the demand response terminal, the interoperation test of the demand response aggregation system and the demand response terminal, and the interoperation test among the power grid demand response service system, the demand response aggregation system and the demand response terminal are sequentially completed. The test system obtains the total score of the air conditioner load and the power grid interoperation test according to the configured test score weight coefficients, and gives the final evaluation: if the total score U>88, it is determined that the load resource and the power grid interoperation test are qualified, further, if the total score U>95, it is determined that the load can completely participate in the power grid interaction, and the test report is output.

[0055] Embodiment 2

[0056] Please refer to Figure 1 According to the residential small and micro load and the power grid interoperation test method of embodiment 1, the embodiment provides a residential small and micro load and the power grid interoperation test system, which includes an interconnection test module, a protocol test module, a judgment protocol module, a scene test and evaluation module;

[0057] Before the interconnection test, the interoperation test system is first built to simulate the power grid side, and the interoperation test among the residential small and micro loads is performed;

[0058] Please refer to Figure 2As shown, the interoperation test system simulates the grid side, which is composed of a test bench, an interoperation test software, a local communication access, a remote communication access, and a metering system. The device under test is connected to the interoperation test software through local networking to carry out interoperation test. The interoperation test software can also be connected to a third-party cloud platform through remote communication to carry out interoperation test. The test bench simulates a typical household energy consumption scenario, and the electrical appliances are typical household smart devices with WIFI modules and capable of local networking communication. The test bench can meter the power of a single device, and the power meter data is uploaded to the interoperation test software.

[0059] The interoperation test selects the first interactive networking mode and / or the second interactive networking mode. The first interactive networking mode is WIFI networking.

At the same time, ordinary home appliances in the smart home appliance inventory are connected to the interoperation test system through WIFI Internet of Things sockets. The second interactive networking mode is HPLC networking. Home appliance devices with HPLC modules are connected to an indoor smart gateway through HPLC. The smart gateway directly communicates with the interoperation test system. Ordinary home appliances in the smart home appliance inventory are connected to the interoperation test system through HPLC Internet of Things sockets.

[0060] Please refer to Figure 3 As shown, the air conditioner load in the resident household is a user-side high-energy-consumption electrical appliance.

If the interoperability test is qualified, the interoperability test is qualified if a handshake is successful and a message required to be replied according to the interoperability test system is received. If the interoperability test is not qualified, the interoperability test is not qualified, and the interoperability test system directly stops the test and outputs an unqualified report. After the interoperability test is qualified, the protocol consistency test process is automatically entered according to a setting of the interoperability test system. The interoperability test system obtains a communication protocol used by the small and micro load device on the resident side, selects a test case corresponding to the protocol, and performs the protocol consistency test process.

[0066] The judgment protocol module is configured to determine whether the protocol consistency test process is qualified. If each test item of the protocol consistency test process is passed, the interoperability test process in each scene is entered. If each test item of the protocol consistency test process is not passed, the interoperability test result is directly determined to be unqualified, and a test report is output.

[0067] Meanwhile, after the protocol consistency test process is qualified, the interoperability test process in each scene is performed. According to a demand response information interaction typical scene design, scene test is performed. The scene test includes:

[0068] The first scene is an interoperability test between a power grid demand response service system and a demand response terminal.
