Description

Technical Field

[0001] The present invention relates to a new energy microgrid system with storage function, equipment and control method thereof. The equipment with storage function is not limited to photovoltaic inverters. Photovoltaic inverters include photovoltaic grid-connected inverters, photovoltaic off-grid inverters or photovoltaic on-grid and off-grid inverters. Background Art

[0002] With the rapid development of new energy systems, inverters, as the core components of new energy microgrid systems, play a role in energy conversion. The inverter itself has a lot of information and parameters. At the same time, different countries, regions, and customers want to understand and even participate in the control of new energy microgrid systems. Moreover, such control is specific, which creates the need for information interaction. Information must be readable, writable, and storable, and the equipment must also adapt to different needs. All these complex information is stored at the bottom layer of the device, but the bottom storage device has a limited service life. The existing control scheme is to organize the requirements into standardized content and then store them separately according to different regions. In order to increase reliability, the storage content will also be backed up additionally, which will occupy more memory and increase the manufacturing cost of the equipment. After modification, the default parameters cannot be restored, which increases the maintenance cost. Conventional storage media can use a single part about 100,000 times, and each change will reduce the service life of the equipment.

[0043] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] Comparative Example

[0045] Reference Figure 1 As shown, assuming that the device has a total of N requirements, each requirement can be summarized into different data and placed in the nA area of ​​the application layer, n = 1, 2, ..., N. Each area contains nA-H, nA and verification, where nA-H is the information overview and nA is the specific data. A backup area nB must also be set. After the device selects a standard area n, it identifies the information overview of nA-H according to the read and write requirements, reads specific content, and writes it to the original area nA after updating it in the logical processing layer. Since the requirements contain a lot of content: including but not limited to protection values ​​and protection times, repeated control and writing will reduce the life of the storage medium at the application layer, and enabling the backup area will also increase costs. At the same time, the default values ​​cannot be restored after the parameter settings are abnormal, and you can only wait for repairs and find the original factory to handle it, which increases maintenance costs.

[0046] Example 1

[0047] The following embodiments provide a new energy microgrid system with storage function, specifically a photovoltaic microgrid system and its equipment. Figure 2 As shown, the new energy microgrid system mainly includes five modules: interaction layer, transmission layer, data processing layer, logic processing layer and application layer. These modules can be set in one or more devices, including but not limited to photovoltaic inverters, photovoltaic inverters including but not limited to photovoltaic grid-connected inverters, photovoltaic off-grid inverters or photovoltaic grid-connected and off-grid inverters. For example, the interaction layer may include a control panel of a photovoltaic inverter, and the application layer may be a storage device of the photovoltaic inverter.

[0048] The interaction layer is used for human-computer interaction, and its functions include control parameter reading and writing, equipment information reading and writing, operating parameter display, and fault information display. The transmission layer includes a wired transmitter and / or a wireless transmitter, and the transmission layer is used for data interaction between the interaction layer and the data processing layer. The data processing layer is used to convert the data from the transmission layer and send it to the logic processing layer, and to convert the data read by the logic processing layer and send it to the transmission layer. The logic processing layer processes the data according to the data reading and writing logic method and sends it to the data processing layer, or writes it to the application layer. The function of the application layer includes data storage. For example, the user input requirements can be received through the interaction layer, and the transmission layer sends it to the data processing layer. The logic processing layer reads the data in the corresponding area of ​​the application layer according to the user's requirements or updates the data and writes it to the corresponding area.

[0049] Reference Figure 3 As shown, the application layer includes an original area 10 and a public area 20 for storing data. The original area 10 includes original storage areas 1 to N, which store data corresponding to N requirements respectively. Each original storage area includes an information overview (1-H, 2-H to NH), stored data and verification. The information overview includes but is not limited to fixed coding (used to distinguish different requirements), storage time, verification, etc. The stored data includes but is not limited to equipment information, operation information, fault information, historical records, grid-connected safety parameter information and grid-connected performance parameter information, etc. The area can also be divided into details again, and each type of requirement is stored separately, including information overview, storage time, data, verification, etc. The verification calculation method includes but is not limited to -sum verification, parity verification, CRC verification, MD5 verification, etc. nH, n, N verifications together constitute the original area 10 of the application layer, n = 1, 2, ..., N.

[0050] The public area 20 includes M public storage areas 201, where M can be a positive integer greater than or equal to 1, and further, M is less than N. Each public storage area 201 includes an information overview (XH), stored data, and a checksum. The information overview includes, but is not limited to, a fixed code (used to distinguish different requirements), storage time, a checksum, and the like. The stored data includes, but is not limited to, equipment information, operation information, fault information, historical records, and the like. Checksum calculation methods include, but are not limited to, a sum check, a parity check, a CRC check, an MD5 check, and the like. In theory, the more public areas are reserved, the more reliable the equipment is.

[0051] Furthermore, the application layer may also include one or more remaining spaces. The remaining spaces may be used to store default values ​​corresponding to the N requirements, and the default values ​​of the N requirements may also be stored in non-application layer modules, including the above-mentioned data processing layer or logic processing layer.

[0052] The logic processing layer is used to read data from the original area of ​​the application layer and write the data to the public area. The logic processing layer is also used to read data from the original area or the public area of ​​the application layer, and update the data parameters as required, and write the updated data to the public area. Further, the logic processing layer is also used to check whether the data read from the original area passes, and after the number of read errors exceeds a set value, restore the data to the default value, and write the data restored to the default position to the public area.

[0053] Each public storage area corresponds to a storage address. The logic processing layer is also used to read data from a public storage area in the public area and verify whether it passes. After the number of read errors exceeds a set value, the reserved storage address is replaced, the information overview is updated, and the data is written to another corresponding public storage area in the public area.

[0054] This embodiment also provides a device of a new energy microgrid system with a storage function, in which the above-mentioned application layer is provided, and the application layer includes an original area and a public area for storing data. The original area is used to store device information, operation information, fault information, and historical record information. The public area is used to write information read from the original area, and the public area is also used to write data updated by the logic processing layer. The public area includes a plurality of public storage areas, each of which corresponds to a storage address; the public area is also used for the logic processing layer to read data from one of the public storage areas and replace the reserved storage address after the number of read errors exceeds the set value, update the information overview, and write the data to the corresponding other public storage area. The public area is also used to write data restored to the default value after the number of errors in reading data from the original area exceeds the set value.

[0055] Specifically, the device may be a photovoltaic inverter, which includes a photovoltaic grid-connected inverter, a photovoltaic off-grid inverter, or a photovoltaic on-grid and off-grid inverter.

[0056] Reference Figure 4 As shown, the control method of the new energy microgrid system includes the following steps:

[0057] (A) Reading data from the original area of ​​the application layer and writing the data into the public area of ​​the application layer after verification;

[0058] (B) Read data from the public area of ​​the application layer and write the updated data into the public area.

[0059] In step (A), if the number of read errors during verification exceeds a set value, the data is restored to a default value, and the data restored to the default value is written into the public area.

[0060] In step (B), data is read from the public storage area of ​​the corresponding address in the public area, and after verification, the data is temporarily stored in the logic processing layer. The logic processing layer updates the data parameters as required and writes the updated data to the corresponding public storage area; if the number of read errors during verification exceeds the set value, the reserved storage address is replaced, the information overview is updated and the verification value is calculated, and the updated data is written to another public storage area corresponding to the reserved storage address.

[0061] The control method is specifically implemented as follows:

[0062] S100, after the device of the new energy microgrid system is turned on, it is determined whether there is data in the reserved public area in the application layer to determine whether the device is used for the first time. If yes, it proceeds to step S300; if no, it proceeds to step S200;
