Multi-objective Optimal Dispatch Strategy Considering Reactive Power Support Performance of Wind Farm
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 re-active 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 satisfac-tion interval was constructed,and a multi-interval dynamic optimization model of the system was estab-lished.The adaptive chaotic differential krill herd algorithm(A-CDKH)was proposed to address the non-linear and multi-constraint characteristics of the reactive power optimal dispatch problem.Finally,the ad-vantages and effectiveness of the proposed strategy were proved through the simulation results of the modi-fied IEEE30-node model and an actual wind farm model.Results show that,compared with the multi-ob-jective fuzzy optimization model,the maximum voltage deviation index obtained by the multi-objective dy-namic optimization model can reach 32.99％optimization degree.The A-CDKH can optimize 75.94％com-pared with other algorithms in the voltage deviation index.
