Abstract
In recent years, information security has become a significant issue in the energy sector. And the inability to control information can cause irreparable damage to the network. Therefore, we need measuring devices for better monitoring and control of the network, but due to financial limitations, it is not possible to install these devices in all nodes. In the state estimation process, the placement of measurement devices at optimal locations is of great importance. Therefore, by determining the best possible combination of measurement devices, including their type, location, and quantity, desirable results can be achieved. Therefore, this research presents the optimal placement of measuring devices with the aim of reducing the state estimation error. Also, the reliability of the measuring equipment and related costs are computed and optimized during the optimization procedure. The results of this research have been analyzed in two systems of 33 and 69 bus. The simulation results are compared with the conventional methods of the past and the results show the better performance of this method than the previous methods.
