An inverter supporting online reconfiguration of a control strategy and an online reconfiguration method

Abstract

The invention discloses an inverter supporting online reconfiguration of control strategies and a method for supporting online reconfiguration of control strategies. An inverter that supports online reconfiguration of control strategies includes a controller, the controller includes a microprocessor and connected to the microprocessor: a memory for storing the control strategy; a sensor interface for receiving information collected by the sensor data; a communication interface, used for exchanging data with external devices; when the controller is running, at least one policy running process and one policy management process are opened, and after the policy management process performs an online strategy switching operation, it only needs to suspend the policy running process, After reconfiguring and rerunning, the new control strategy after switching can be executed. The inverter provided by the invention does not need to restart the inverter when adding, updating or switching control strategies. Compared with the traditional inverter, the inverter designed by the invention has stronger scalability and online reconfiguration , more suitable for the open operating environment of the microgrid.

Description

technical field [0001] The invention relates to the field of inverters, in particular to an inverter supporting online reconfiguration of control strategies and an online reconfiguration method. Background technique [0002] With the increasingly serious problems of energy supply and environmental pollution, the development of recyclable and environmentally friendly clean energy has become an inevitable choice for my country to ensure energy supply security, cope with climate change, and improve environmental quality. Since the microgrid represented by distributed generation (DG) can not only realize the diversification and intelligence of the use of renewable energy, but also better meet the user's requirements for power quality and reliability, the microgrid is gradually changing from The laboratory stage has entered into engineering practice. It is worth pointing out that with the gradual practical application of the microgrid, the structure of the microgrid is becoming ...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides an inverter that supports online reconfiguration of the control strategy. The inverter can realize the dynamic adjustment of the control strategy as the operating state of the microgrid changes, and overcomes the traditional inverter using a single, predefined control The strategy is difficult to meet the defects of the complex and changeable operating environment of the microgrid system
