Abstract

In view of the economy of reactive power compensation for micro grids

the reactive power optimal compensation model considering the installation and operating costs of STATCOM is proposed.Considering the uncertainty of distributed generation output

the calculation of line loss is divided into multiple time periods for calculation superposition based on seasons and daily hours.At the same time

the deviation penalty function is introduced to limit the reactive power output and the overall voltage level of the distributed power.The optimal compensation position and capacity is defined by way of two-stage cuckoo search algorithm using lineloss sensitivity for the initial population.The IEEE 14 node system is adopted

the multiple distributed powers are connected to the microgrid system and simulation verification is performed by Matlab platform.The economy of the proposed optimal compensation strategy is analyzed by plotting curves and the effectiveness of the compensation effect is verified by way of comparison with various algorithms.
