Series compensation control method and device design for solving the low voltage problem at the end of distribution network
To solve the low voltage problem at the end of the distribution network, design a voltage compensation system based on series compensation control. With the objective of minimizing the loss of active power and minimizing the average voltage deviation of the node, an optimal configuration model of the installation position and capacity of the compensation device was established. Considering the voltage static characteristics of the load, and the influence of the compensation device on the distribution of power flow in the front section of the access point, a power flow model added the compensation device and a calculation method for solving it was established. Taking a typical area has a low voltage problem as an example. Compared with the voltage characteristics status that before adding the compensation device. The results show that the designed system can achieve all the node voltage of the line to meet the power supply index with 1/10 compensation capacity of the line load, that solves the original low voltage problem effectively.
