ABSTRACT

Aiming at the relative decoupling of active and reactive power in power grid, a linear phase estimation model based on active voltage measurement for voltage phase estimation and a linear voltage estimation model for voltage amplitude estimation using voltage amplitude measurement and zero injection measurement are proposed. The performance test of the node system shows that the algorithm has a faster calculation speed, can effectively save memory, and has high efficiency.
