Annual Economic Benefits

The optimization results show that, through the reactive power compensation, the
voltage quality of nodes and the power factor of branches all have been improved, the
reduced operation cost and the annual economic benefits are obvious.

5 Conclusion

Through the practical example, the results prove that the new increased reactive
compensation devices can decrease the network loss and improve the quality of
voltage, the economic benefits are very obvious, and the mathematical optimization
model and quadratic programming algorithm is reasonable and effective.
