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

Optimal PMU placement considering topology constraints
International Journal of Electrical Power & Energy Systems, 2015 Abstract A new optimization algorithm for optimal PMU configuration based on combination of graph theory and genetic algorithm is proposed. According to four topology reconstruction rules and three PMU configuration rules based on the graphic relationships between PMUs, constraints of PMU placement are put forward through topology constraint analysis,
