- Abstract:
- Reaclive power oplimizalion problem is a muli-bound, muli-variable mixed integer programmingproblem, and the operating variables inelude continuous and diserete variables, so the optimization problembecomes complex. In view of the diserete charaeteristies of and compensation capacitor sets, this paper adoplsa simple and practieal approach, an auxiliary funetion is structured to express the input or withdrawal of capae-itor sets. This method transorms diserete variables into continuous variables. The oplimal objeetive is to mini.mize the competitive expenses of power loss and the cost of equipment regulation. Variable metrie algorithm isadopted to solve the oplimal problem. Proposed approach is examined on one system ; eomputed results providethe active power losses and capaeitor states. The proposed approach is examined in one testing system.
