| Popis: | This study aims to ensure the observability of voltage sags in the entire distribution system (DS) for any short-circuit manifested by the optimal allocation of monitors focusing on power quality. After determining a voltage sag matrix for each type of short-circuit (balanced or unbalanced), a resulting binary matrix is determined which simultaneously observes the voltage sags for all types of faults. Later, a proposal is made to reduce this matrix to decrease the computational effort in large DS. Furthermore, the vulnerability of each node is analysed to establish the monitors' installation priority. The IEEE 13-nodes distribution test system is used to describe each step of the methodology in detail. Moreover, the IEEE 123-nodes distribution test system is used to validate the results observed so far. |
