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,
