“…The locations of PMUs are: buses 2, 8, 11, 15, 17, 20, 24, 26, 30, 32. Considering the cost and state estimation accuracy comprehensively, the compromise solution is selected by TOPSIS. The compromise solution needs 11 PMUs, and the locations are buses 2,4,8,11,15,17,20,24,26,30,32. In order to reflect the influence of network compression on OPP, this paper uses the single variable method to compare two cases, the result of the comparison is shown in Table 1.…”

“…The main purpose of improving network measurement redundancy is to improve the accuracy of state estimation. The distribution network state estimation technology is expected to be able to monitor the operating status of the system accurately and provide reliable data for other advanced management software of the active distribution network, such as transient stability [24], voltage security visualization [25], fault location identification [26], dynamic control strategies [27] and so on. Therefore, taking state estimation accuracy instead of network measurement redundancy into the OPP problem can be more helpful to improve the observability and controllability of the distribution network.…”

A phasor measurement unit (PMU) can provide phasor measurements to the distribution network to improve observability. Based on pre-configuration and existing measurements, a network compression method is proposed to reduce PMU candidate locations. Taking the minimum number of PMUs and the lowest state estimation error as the objective functions and taking full observability of distribution network as the constraint, a multi objective model of optimal PMU placement (OPP) is proposed. A hybrid state estimator based on supervisory control and data acquisition (SCADA) and PMU measurements is proposed. To reduce the number of PMUs required for full observability, SCADA measurement data are also considered into the constraint by update and equivalent. In addition, a non-dominated sorting genetic algorithm-II (NSGA-II) is applied to solve the model to get the Pareto set. Finally, the optimal solution is selected from the Pareto set by the technique for order preference by similarity to ideal solution (TOPSIS). The effectiveness of the proposed method is verified by IEEE standard bus systems.

“…The proposed method requires PMU at each bus of the protected network for state estimation in real time. Another method based on real‐time state estimation of the network using PMU measurements is presented in a previous study . The state estimator requires fault currents of the generator and voltage measurement at some nodes for fault location estimation.…”

In the last decade, with increasing power supply from distributed generation (DG) to the distribution system, the traditional passive radial distribution systems transformed into an active multisource system. The nature of fault location schemes designed for the distribution system has traditionally been based on unidirectional power flow assumptions, making them ineffective for a distribution system with a higher level of DG penetration. New grid regulations require DGs to remain connected to the system in the event of a fault to provide support to the grid and improve system reliability. This makes the fault location process important as the timely location of a fault speeds up the restoration process, which improves the system reliability. Herein, providing a comprehensive review of the available techniques for fault location in the distribution system with DG penetration is focused on. An analysis is given on the shortcomings of traditional protection methods when applied to DG‐integrated distribution systems. A comparative analysis is carried out in which the merit and demerit of each technique is assessed. A discussion on some other important technical issues arising due to DG integration, such as effects on the stability of the distribution system, is also given.

“…The third group used high-precision measurement units. The phasor measurement unit (PMU) is one of the high precision measurement units with characteristics such as phasor measurements and synchronization of measurements [11,12]. Usman et al assumed every bus of a distribution network as a fault point and estimated a voltage through state estimation based on weighted least squares by using current values at PMUs.…”

This paper proposes a fault location method for power distribution networks using phasor measurement units (PMU) and short circuit analysis. In order to improve the problems of the existing studies, we focused on several approaches as follows. First, in order to minimize the number of PMU installations, a fault location estimation of lateral feeders through short circuit analysis was presented. Second, unbalanced faults and impacts of photovoltaic (PV) were considered. The proposed method consists of two stages. In Stage 1, the fault location was estimated for the main feeder using PMU installed at the start and end points of the main feeder. Symmetrical components of voltage and current variation were calculated by considering the impact of PVs interconnected to the lateral feeders. If the result of Stage 1 indicated a connection section of lateral feeder on the main feeder, Stage 2 would be performed. In Stage 2, the fault location was estimated for the lateral feeder by comparing the results of the short circuit analysis and measurements of PMUs. The short circuit analysis was based on an unbalanced power flow that considered dynamic characteristics of the PV inverter. The proposed method was verified through various fault situations in a test system. For the applicability of the proposed algorithm to the actual system, a noise test was also performed.
