Abstract In view of the construction cost of networked power quality monitoring system (NPQMS) and the location requirement of power quality disturbance source (PQDS), a method for optimal allocation of power quality monitors (PQM) in meshed multiple-source distribution networks is proposed. Through characteristics analysis of the topology of meshed multiple-source networks, the matrixes of structure information is described, general principles of PQM allocation and weighted factors corresponding to different endpoints are defined. With establishing of the optimal model of the optimum allocation for monitoring points, the optimum position monitoring arrangement can be obtained by inspecting the system ambiguity through monitoring observability matrix. The definition of positive direction in this method matches with that in the general methods for PQDS location, which makes the accurate location of the PQDS feasible which based on the results of the optimization allocation of PQM. It can also offer decision support to the stagewise construction scheme of the NPQMS. Finally, with the example of the IEEE 14-bus system, the feasibility and validity of the presosed method are demonstrated.
