Problems solved by technology

[0003] Information transmission is performed every fixed time interval. When the local state quantity does not change greatly at adjacent communication moments, the current state will still be transmitted each time. In fact, there is no need to perform communication operations at this time. Therefore, communication in time-triggered mode will cause waste of resources and increase communication pressure

Abstract

The invention discloses a high-density distributed power supply communication method, and the method comprises the steps: collecting local latest state information at a current control moment, local state information at a last trigger moment, and neighbor power supply latest state information of a neighbor power supply; whether the current control moment meets the triggering condition or not is judged by calculating the difference value between the local newest state information and the state information of the last triggering moment and the unbalance amount between the state information of the last triggering moment and the newest state information of the neighbor power supply, and if yes, the local newest state information is sent to the neighbor power supply. The information is transmitted only when the triggering condition is met, so that the problem of resource waste caused by the fact that the information is still transmitted when the local state quantity of the adjacent control moments does not change greatly is solved. In addition, the invention further provides a device and a medium which correspond to the high-density distributed power supply communication method and have the same effects.

Description

technical field [0001] The present application relates to the field of grid communication, in particular to a high-density distributed power communication method, device and medium. Background technique [0002] With the depletion of the earth's resources and people's attention to environmental issues, the application of renewable energy has attracted more and more attention from all over the world, and the large-scale access of distributed power to the distribution network has become the current development trend. However, considering the randomness and volatility of new energy sources such as photovoltaics and wind power, the access of high-density distributed power will bring challenges to the safe and stable operation of the distribution network. How to maintain stable voltage and frequency of the system, highly reliable power supply, realize flexible and efficient multi-source coordinated control, and then improve the capacity of renewable energy consumption are the foc...
