Reactive Power Compensation Devices Optimization Based on Improved Ant Colony Algorithm

In the assumption that all load nodes are installed reactive power compensation device, injecting a variety of disturbances to the grid, through the application of improved ant colony algorithm, we can obtain the optimal control sequence under disturbance, that is current switching reactive power compensation device node location. Comparing control sequences under the various perturbations, with circulation mechanism of successive exclusion, the best installation location of reactive power compensation devices is obtain, while the system voltage deviation smaller, improving power system operation economy. In this paper, there is a planning example, the results show that the proposed method is feasible.
