A newly developed reactive power optimization software for large power systems is introduced. The software uses a newly proposed mathematical model. It can achieve the goal of minimizing the total active power loss of the whole network, and also can minimize the active loss of the direct power line. For the Internet, it can optimize both the entire network and the individual power networks. The algorithm uses a very efficient interior point algorithm for large-scale optimization problems. By applying the Hausdorff theorem, the sparsity of the constraint matrix is maintained, sparse techniques and programming techniques are fully utilized, resulting in greatly reduced memory consumption and faster computation speed. Through a large number of calculation of a number of IEEE standard network and Huazhong power system, it shows that the software has a lot of advantages such as practical function, easy to use, quick calculation, reasonable calculation results and good robustness.
