Embodiment Construction
[0038] The design idea of the present invention is: aiming at the main problems existing in the existing technical solutions, and using the characteristics of ADN having a relatively complete communication network and measurement system, an RTU-based feeder voltage online control method is proposed. The main characteristics of the method Because: 1) The data of renewable energy power generation and load forecasting are not required; 2) In addition to measuring local data, the new RTU also undertakes some simple calculations, which reduces the calculation amount of the main controller of the feeder voltage and improves the efficiency of control decision-making; 3) The voltage sensitivity calculation method based on the loop power flow method is adopted, which has a small amount of calculation and meets the real-time requirements of voltage online control; 4) The extreme value of the local voltage and the surrounding load node voltage is the control object, ensuring that the nod...
