Abstract--In order to meet the requirements of real-time

control for reactive power optimization, this paper puts forward

a new reactive power optimization method in area power grid,

which is the secondary optimization control of voltage and

reactive power in area power grid based on improved Tabu

search algorithm. firstly, the minimum active power loss is

chosen as objective function, and the improved Tabu search

algorithm is applied to the reactive power optimization, in which

the top 10 solutions are recorded; secondly, static voltage

stability margins for the top 10 solutions are calculated; thirdly,

by using fuzzy set theory, the two objectives including the

minimum active power loss and the maximum margin index are

converted into single objective, at last, solution corresponding

the maximum of single objective function is the final optimal

result of reactive power optimization in area power grid.

Simulation results indicate that, not only is the improved Tabu

search algorithm suitable to solve reactive power optimization in

area power grid, but also the secondary optimization control of

voltage and reactive power in area power grid based on

improved Tabu search algorithm and considering static voltage

stability is practicable and effective.
