In order to solve the problem of inadequate reactive power compensation under the background of high proportion of new energy resources access
a multi-objective optimal dispatch strategy considering reactive power support performance of wind farm was proposed. The reactive power support performance of wind farm was analyzed from the aspects of voltage stability
reactive power margin safety and power loss economy of the power system operation. A quadratic function group considering multi-objective satisfaction interval was constructed
and a multi-interval dynamic optimization model of the system was established. The adaptive chaotic differential krill herd algorithm (A-CDKH) was proposed to address the nonlinear and multi-constraint characteristics of the reactive power optimal dispatch problem. Finally
the advantages and effectiveness of the proposed strategy were proved through the simulation results of the modified IEEE30-node model and an actual wind farm model. Results show that
compared with the multi-objective fuzzy optimization model
the maximum voltage deviation index obtained by the multi-objective dynamic optimization model can reach 32.99% optimization degree. The A-CDKH can optimize 75.94% compared with other algorithms in the voltage deviation index.
