Groebner bases algorithm for optimal PMU placement
International Journal of Electrical Power & Energy Systems, 2020 Abstract In this paper a new method for solving optimal phasor measurement units (PMU) placement problem for full observability in power systems is proposed. A new algorithm is based on forming and solving Groebner bases set of equations for a defined optimization problem.
