Considering the DDC component estimation, this paper transforms the phasor problem into a compressive sensing model based on the regularity and sparsity of the dynamic harmonic signal distribution. It then derives an optimized hybrid regularization algorithm with the Bregman split method to reconstruct the dynamic phasor estimation. The accuracy of the model was verified by using the cross entropy to measure the distribution differences of values. Composite tests derived from the dynamic phasor test conditions were then used to verify the potentialities of the BSCS method. Simulation results show that the algorithm can alleviate the impact of dynamic signals on phasor estimation and significantly improve the estimation accuracy, which provides a theoretical basis for P-class phasor measurement units (PMUs).<\/jats:p>","DOI":"10.3390\/e24070988","type":"journal-article","created":{"date-parts":[[2022,7,17]],"date-time":"2022-07-17T21:00:28Z","timestamp":1658091628000},"page":"988","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Bregman-Split-Based Compressive Sensing Method for Dynamic Harmonic Estimation"],"prefix":"10.3390","volume":"24","author":[{"given":"Aobing","family":"Chi","sequence":"first","affiliation":[{"name":"College of Electrical Engineering, Sichuan University, Chengdu 610044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengbi","family":"Zeng","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering, Sichuan University, Chengdu 610044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yufu","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering, Sichuan University, Chengdu 610044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Miao","sequence":"additional","affiliation":[{"name":"College of Electrical Engineering, Sichuan University, Chengdu 610044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Farajollahi, M., Shahsavari, A., and Mohsenian-Rad, H.
