AI Technical Summary

Technical Problem

Existing wireless parallel control schemes in distributed generation systems suffer from insufficient time synchronization accuracy, unreliable transmission, and inconsistent power parameter acquisition times, leading to a decrease in power balance adjustment accuracy and dynamic response performance.

Method used

By acquiring local clock deviation data from distributed units for time synchronization calibration, a local power parameter sequence with time tags is generated, which is encapsulated into a synchronization message and pre-distributed. The response data is used to construct a distribution strategy, calculate the power deviation value, generate a control signal for power regulation optimization, and combine a high-precision time source, moving average filtering, hierarchical clustering and fuzzy PID control algorithm to achieve accurate synchronization and power balance.

Benefits of technology

It improves the time synchronization accuracy and coordination control efficiency of distributed generation systems, enhances the stability and economy of system operation, and ensures that power regulation converges quickly and smoothly to an equilibrium state.

Abstract

A kind of time synchronization control method and system for distributed power generation system, comprising the following steps: obtaining the local clock deviation of each distributed unit and time calibration, collecting the running power data after calibration, generating local power parameter sequence with time label.It is encapsulated as synchronous message and sent to host end, by pre-distribution to message and obtaining each unit response data, evaluate the message reception integrity of each unit at the same time point, to determine the final distribution strategy.According to the strategy, distribute synchronous message, and calculate the deviation value of each unit local power and network average power.According to the power deviation value, the control signal of each unit is generated, and the power regulation optimization of distributed power generation system is realized.The present application effectively improves the precision and coordination control efficiency of system time synchronization, enhances the stability and economy of system operation.
