The ORPD is a nonlinear and nonconvex optimization problem that involves both discrete and continuous variables; the former include transformer tap positions and settings of reactor banks, while the latter include voltage magnitude settings in generation buses. In this paper, the ORPD problem is modeled as a mixed integer nonlinear programming problem and solved through two different metaheuristic techniques, namely the Mean Variance Mapping Optimization and the genetic algorithm. As a novelty, the solution of the ORPD problem is implemented through a Python-DIgSILENT interface that combines the strengths of both software. Several tests were performed on the IEEE 6-, 14-, and 39-bus test systems evidencing the applicability of the proposed approach. The results were contrasted with those previously reported in the specialized literature, matching, and in some cases improving, the reported solutions with lower computational times.<\/jats:p>","DOI":"10.3390\/computation10080128","type":"journal-article","created":{"date-parts":[[2022,7,25]],"date-time":"2022-07-25T21:20:59Z","timestamp":1658784059000},"page":"128","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Solving the Optimal Reactive Power Dispatch Problem through a Python-DIgSILENT Interface"],"prefix":"10.3390","volume":"10","author":[{"given":"Martin M.","family":"S\u00e1nchez-Mora","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica, Facultad de Ingenier\u00eda, Universidad de Antioquia, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David Lionel","family":"Bernal-Romero","sequence":"additional","affiliation":[{"name":"Grupo de Compatibilidad e Interferencia Electrom\u00e1gnetica, Facultad de Ingenier\u00eda, Universidad Distrital Francisco Jos\u00e9 de Caldas, Bogot\u00e1 110231, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6051-4925","authenticated-orcid":false,"given":"Oscar Danilo","family":"Montoya","sequence":"additional","affiliation":[{"name":"Grupo de Compatibilidad e Interferencia Electrom\u00e1gnetica, Facultad de Ingenier\u00eda, Universidad Distrital Francisco Jos\u00e9 de Caldas, Bogot\u00e1 110231, Colombia"},{"name":"Laboratorio Inteligente de Energ\u00eda, Facultad de Ingenier\u00eda, Universidad Tecnol\u00f3gica de Bol\u00edvar, Cartagena 131001, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1466-7266","authenticated-orcid":false,"given":"Walter M.","family":"Villa-Acevedo","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica, Facultad de Ingenier\u00eda, Universidad de Antioquia, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2369-6173","authenticated-orcid":false,"given":"Jes\u00fas M.","family":"L\u00f3pez-Lezama","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica, Facultad de Ingenier\u00eda, Universidad de Antioquia, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Villa-Acevedo, W.M., L\u00f3pez-Lezama, J.M., and Valencia-Vel\u00e1squez, J.A.
