Abstract
The effectiveness of a relatively simple Teager energy operator (TEO)-based single-phase grid synchronization method, which relies on a second-order generalized integrator (SOGI), is affected in the presence of lower-order harmonics. Additionally, the SOGI-based orthogonal signal generator may be impacted by integrator discretization errors, altering the pole-zero distribution compared to the continuous domain. These discretization errors can accumulate over time, potentially leading to stability issues. To overcome such limitations of the SOGI-TEO method, this paper proposes an improved TEO-based method that avoids using the SOGI by combining the TEO with a delayed signal cancellation approach. Simulations and experiments are conducted to verify the enhanced response of the offered TEO-based method.
