The Research on Equivalence Network Concentrated with Wind Farms

Abstract

The Ward equivalent approach is used in the initial network equivalence, the network includes the concentrated wind farms. According to the principle of equivalence, the equivalent network is dealt with further. The dynamic load model and wind farms are added into the equivalent network, so that the dynamic performance of them can still be counted. Then the simulation is executed in an actual system of 99 nodes, the result of simulation of the original network and equivalent network is compared, so as to verify the accuracy of this equivalent method.
