# Getting \textcite to show only author last name when we have a single author

I want to use the command \textcite in biblatex, but when the reference has a single author, the command shows the last name seperated by a comma from the first name. How can we let only the last name to be visible?

\begin{filecontents*}{sample.bib}
@online{lovelace2015low,
author = {{Lovelace, Will}},
title = {{Low SCR Wind Integration and Mitigation}},
url = {http://www.cce.umn.edu/documents/CPE-Conferences/MIPSYCON-PowerPoints/2015/PGLowSCRWindGenerationInstabilityIdentificationandMitigation.pdf},
organization = {Minnkota Power Cooperative},
date = {2015-11-11},
urldate = {2019-05-20}
}
\end{filecontents*}

\documentclass{report}
\usepackage[style=alphabetic]{biblatex}

\begin{document}

\textcite{lovelace2015low}

\printbibliography

\end{document}


Just write

author = {Lovelace, Will},


The double braces in author = {{Lovelace, Will}}, stop Biber (and BibTeX) from parsing the name as the name of a person with family and given names. Instead the name is just interpreted as consisting of the family name "Lovelace, Will". This is desirable for corporate authors (see Using a 'corporate author' in the "author" field of a bibliographic entry (spelling out the name in full)), but not for people.

You can find out more about the valid input formats for names in How should I type author names in a bib file?.

I also remove the WYSIWYG bracing from the title field. See Proper casing in citation/bibliography titles using biblatex/Biber, Capitalize words in Bibtex files: {Word} or {W}ord?, What is the proper casing to use when storing titles in the bibliography database? and more.

\documentclass{article}
\usepackage[style=alphabetic]{biblatex}

\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@online{lovelace2015low,
author       = {Lovelace, Will},
title        = {Low {SCR} Wind Integration and Mitigation},
url          = {http://www.cce.umn.edu/documents/CPE-Conferences/MIPSYCON-PowerPoints/2015/PGLowSCRWindGenerationInstabilityIdentificationandMitigation.pdf},
organization = {Minnkota Power Cooperative},
date         = {2015-11-11},
urldate      = {2019-05-20},
}
\end{filecontents*}

\begin{document}
\textcite{lovelace2015low}

\printbibliography
\end{document}


If you want the author to appear as

Lovelace, Will

and not as

Will Lovelace

in the bibliography, you need

\DeclareNameAlias{author}{sortname}
\DeclareNameAlias{editor}{sortname}
\DeclareNameAlias{translator}{sortname}

\DeclareNameAlias{sortname}{family-given}
