Optimal PMU Placements Considering System Change
2021In this paper, a new method for optimal phasor measurement unit (PMU) placements is proposed when considering system change. In the method, PMU, zero injection buses (ZIBs) and flow measurements are all considered. When the system changes, there are unobservable buses and new PMUs are needed to guarantee the observability of the system.

Optimal pmu placement for distribution networks
2017 IEEE Innovative Smart Grid Technologies - Asia (ISGT-Asia), 2017This paper presents the optimal phasor measurement (PMU) placement for distribution networks. The optimal PMU placement (OPP) formulation from related literatures is presented in integer linear programming (ILP) framework where zero injection buses (ZIBs), PMU channel limitation, PMU outages and line outages were considered.

Optimal PMU placement with binary PSO
2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012A growing number of Phasor Measurement Units (PMUs) are being installed throughout the power grid. Among other objectives, PMUs can be used in state estimation. Due to the high purchase price of a PMU and its high installation cost, a minimum number of PMUs is desired to make a given power network fully observable.

Optimal PMU Placement Using Stochastic Methods
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019Phasor Measurement Units (PMUs) collect high-precision voltage and current data in order to monitor the performance of a power system. However, it is expensive to implement PMUs on every bus within a power system. Optimal PMU placement (OPP) becomes necessary to minimize the number of PMUs implemented while maintaining full observability of the network.

Placement of PMUs with channel limits
2009 IEEE Power & Energy Society General Meeting, 2009Synchronized phasor measurements are changing the way power systems are monitored and operated. Their efficient incorporation into various applications which are executed in energy management control centers, require strategic placement of these devices. Earlier studies which consider placement of PMUs to be used for state estimation, assume that these

Synchronized PMU placement incorporating communication infrastructure
2016 7th India International Conference on Power Electronics (IICPE), 2016Phasor Measurement Unit (PMU) provides the online state estimation and faster monitoring, protection and control of power system. However, PMU installation at every power system buses is an uneconomical decision. Vowing to this, various methodologies have been suggested in past to determine the optimal locations of these devices in order to retain the ...

Optimal PMU placement for voltage control
2016 IEEE International Conference on Smart Grid Communications (SmartGridComm), 2016This paper deals with the optimal phasor measurement unit (PMU) placement problem. In large power system, it is costly to place too many PMUs to achieve real time global observability. In fact, system state can be well estimated by optimally placed limited PMUs' synchronous measurements.

Prioritization of Locations for PMU Placement
2017 Ninth Annual IEEE Green Technologies Conference (GreenTech), 2017This paper presents a methodology for prioritizing bus locations of a power system for PMU placement. This is based on the identification of strategically important locations of power systems using eigenvalue analysis of the measurements of the system variables.

PMU placement for robust state estimation
2013 North American Power Symposium (NAPS), 2013Least Absolute Value (LAV) estimators that are based solely on phasor measurements are known to be robust against bad data provided that there is enough redundancy in the measurement set. This paper investigates the required level of redundancy and develops a systematic approach to place Phasor Measurement Units (PMU).

Optimal PMU placement for power system restoration
2015 Clemson University Power Systems Conference (PSC), 2015PMU placement is important to achieve full system observability. Traditional PMU placement algorithms only work for systems in normal condition. During power system restoration, system topology and condition change in each step. Synchrophsors can help to improve the reliability and efficiency of restoration strategy. However, the original PMU placement
