Power System Reactive Power Optimization Based on Direct Neural Dynamic Programming
Reactive power optimization in power system is acomplex nonlinear combinatorial optimizationproblem with multiple constrained conditions.However,direct neural dynamic programming(directNDP)approach based on on-line measurements canbe employed in this situation,which is independent ofmodels.In this paper,on the basis of applicableanalysis to reactive power optimization,this algorithmis improved in the expansion of dimension,and then adirect NDP model is established for reactive poweroptimization.It is mainly composed of two neuralnetworks: action network(AN)and critic network (CN),AN is used to control,and CN is used to evaluatecurrent system states and update AN.At last,theimproved algorithm is tested in the IEEE 6-bus systemand compared with the GA optimization algorithm,theresults demonstrate that the new algorithm is afeasible and effective way to solve the reactive poweroptimization problem.
