Optimal PMU placement problem in octahedral networks
RAIRO - Operations Research, 2022 Power utilities must track their power networks to respond to changing demand and availability conditions to ensure effective and efficient operation. As a result, several power companies employ phase measuring units (PMUs) to check their power networks continuously. Supervising an electric power system with the fewest possible measurement equipment is

Improved BPSO for optimal PMU placement [PDF]
2015 50th International Universities Power Engineering Conference (UPEC), 2015 Optimal phasor measurement unit (PMU) placement involves the process of minimizing the number of PMU needed while ensuring entire power system network completely observable. This paper presents the improved binary particle swarm (IBPSO) method that converges faster and also manage to maximize the measurement redundancy compared to the existing BPSO ...

Research on the method of optimal PMU placement
International Journal of Online and Biomedical Engineering (iJOE), 2013 Taking the full network observability of power system and the least number of PMU as objective, to appearing fault situation in the grid, this paper proposes Differential Evolution and Particle Swarm Optimization (DEPSO) algorithm in view of the system failure rate. The improved DEPSO algorithm is global optimization,
