Parallel computing model for time-varied coordinated voltage reactive power control

Abstract EN

To make sure system stability and reduce active power loss are two important tasks of voltage / reactive power optimization control.

To some extent, the two objectives contradict each other, and it is difficult to assess voltage stability considering load changing.

A novel time-varied coordinated voltage / reactive power control model based on parallel ∑▒-domination multi-objective evolutionary algorithm is presented in this paper.

The model calculates load power margin b-y Primal-dual interior point nonlinear programming, which can assess voltage stability quickly, completely and provides operators more accurate information.

Simulation results of IEEE-l-4 bus, IEEE-30 bus and IEEE-118 bus systems show that this approach is valid and effective.
