405 distributed power grid multi-energy complementary power supply output voltage automatic switch control method

The output voltage automatic switching control method based on hierarchical control and the output voltage automatic switching control method based on extreme value optimization do not diagnose the output voltage state of the multi-energy complementary power supply of the power grid.After the control occurs,the reactive power and active power reach a steady state for a long time.The problem resulted in poor automatic switching control of the output voltage of the power supply.Therefore,an automatic switching control method for the output voltage of the 405 distributed power grid multi-energy complementary power supply was designed.Perform simple moving average processing on the grid output voltage data collected in real time,establish a diagnostic function to judge the status of the output voltage,divide the current into the on-period and off-period,and determine the output voltage switching frequency of the grid multi-energy complementary power supply.Taking the minimum deviation of the output voltage of the multi-energy complementary power supply as the objective function,and formulating an acceleration factor to improve the response speed of the automatic switch control of the output voltage of the power supply,in order to complete the automatic switching control of the output voltage of the 405 distributed power supply system.Taking the time for reactive power and active power to reach the steady state as a comparison index,the experiment proves that the method designed this time is shorter than the time for the reactive power and active power to reach the steady state after the traditional two methods are controlled,proving the method of this design The control effect is better than the traditional two methods.
