Optimal PMU Placement Considering Data Integrity Attack

2022 IEEE 16th International Conference on Compatibility, Power Electronics, and Power Engineering (CPE-POWERENG), 2022
Phasor measurement unit (PMU) has been widely used for power system monitoring and protection especially in wide-area monitoring system. However, the cost of PMU is still quite expensive especially considering the number of units that needs to be ...

Optimal PMU Placements Considering System Change

2021
In 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), 2017
This 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), 2012
A 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), 2019
Phasor 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.

Optimal PMU placement for voltage control

2016 IEEE International Conference on Smart Grid Communications (SmartGridComm), 2016
This 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.
