Optimal PMU placement using topology transformation method in power systems
Optimal phasor measurement units (PMUs) placement involves the process of minimizing the number of PMUs needed while ensuring the entire power system completely observable. A power system is identified observable when the voltages of all buses in the power system are known. This paper proposes selection rules for topology transformation method that involves a merging process of zero-injection b...
متن کاملResearch of PMU Optimal Placement in Power Systems
The analysis of power system observability and the rules of PMU placement are concisely presented. Several algorithms of PMU placement as well as their differences and relations are discussed in details: a graph-theoretic procedure based on Depth First Search can find the optimal placement the most quickly; Simulated Annealing Method can help the algorithm converge to global optimum. Base on th...
متن کاملObservability of power systems with optimal PMU placement
Phasor Measurement Units (PMUs) are measuring devices that, when placed in electrical networks, observe their state by providing information on the currents in their branches (transmission lines) and voltages in their buses. Compared to other devices, PMUs have the capability of observing other nodes besides the ones they are placed on. Due to a set of observability rules, depending on the plac...
متن کاملOptimal multi-stage PMU placement in electric power systems using Boolean algebra
Placement of phasor measurement units (PMUs) in power systems has often been formulated for achieving total network observability. In practice, however, the installation process is not implemented at once, but at several stages, because the number of available PMUs at each time period is restricted due to financial problems. This paper presents a novel integer linear programming framework for o...
متن کاملOptimal PMU Placement in Power System Considering the Measurement Redundancy
In this paper, Integer Programming based methodology is presented for the optimal placement of Phasor Measurement Unit (PMU) that minimizes the cost of installation and provide the entire power system observability. The concepts of zero injection buses are used in this paper for further reduction in number of PMUs. Integer Programming may produce multiple results if neighboring buses to zero in...
