Description
Technical Field
The invention relates to the technical field of source network load storage interactive systems, in particular to a source network load storage interactive system-oriented universal control device and method.
Background
The high-speed development in the application fields of smart power grids, new energy power generation, electrified transportation, military equipment and the like has greater and greater requirements on power electronic equipment and systems, and the power electronic equipment is deeply applied in various links of sources, networks, loads and storage to promote the power electronic process of a power system. The above process will be continuously deepened along with the upgrade of intelligent manufacturing, intelligent home and transportation electrical industries. The light direct current valve (AC/DC), the voltage source inverter (DC/AC), the direct current converter (DC/DC), the medium-high voltage traction converter, the active filter (APF), the solid-state circuit breaker (SSB) and other key devices and core interface equipment provide wide-capacity, high-quality, reliable and controllable electric energy conversion and transmission in the source network load storage interactive system. The structural characteristics and the control method of the power electronic equipment are different from those of electromagnetic transformation equipment such as a traditional synchronous unit and the like.
However, the central controller of the power electronic equipment in the prior art has the following two problems: 1. the central controllers are highly heterogeneous in structure, specific function development is mostly carried out according to project requirements, systematic architecture design, platform hardware planning and modularized software functions are lacked, and the problems of low project customization development efficiency and long period are caused. 2. The project aims at the 'customized' central controller of the self power electronic equipment, and the resources such as AD/IO/communication are basically fixed and lack of coordination and universality, so that the power electronic equipment cannot be replaced, and the project is difficult to be suitable for the power electronic equipment with 'good and uneven' control functions.
The prior art (application number: 202010041232.7) discloses a coordination controller and a coordination control method for an energy storage system and a new energy system in a microgrid, wherein the controller comprises a logic control module, a man-machine interaction module, an expansion module, a load, an energy storage system, a new energy power generation assembly and a cloud system, and a CPU module is arranged in the logic control module to complete data processing and logic control; the logic control module is connected with the expansion module to realize real-time uploading of data acquired by the expansion module to the logic control module, and meanwhile, the logic control module transmits the processed data to the expansion module to finish logic control data transmission; the expansion module realizes data acquisition and logic control action. In the application, the logic control module is connected with the human-computer interaction module through a USB. And the communication unit in the expansion module is connected with the energy storage system and the new energy power generation assembly by adopting an RS485 standard. An SPI bus system is arranged between the logic control module and the expansion module. And the uploading of the data of the corresponding module is realized between the logic control module and the cloud system through a TCP/IP protocol. However, the prior art (application No.: 202010041232.7) has several disadvantages as follows: 1. according to typical scene design formed by a new energy power generation assembly, an energy storage system and a load, whether an off-grid type micro-grid application scene which is provided with a diesel power generation system, the new energy power generation assembly, the energy storage system and the load and is suitable for an island is unknown. 2. The logic control module is connected with the human-computer interaction module through a USB. An SPI bus system is arranged between the logic control module and the expansion module. The stability of the USB and SPI communication modes is not high, and the USB and SPI communication modes are easy to interfere. 3. And the method is not compatible with various communication modes and protocols, and cannot automatically match with upper management and regulation, so that the transplantation difficulty is caused. 4. In the application, only the controller is described to have good expansibility, and how to expand the controller is not described, so that the complexity of the expansion is difficult to evaluate.
Therefore, a technology is needed to realize the universal control of the source network-oriented load storage interactive system.
