Answer 1

使用适当宽度subfigures和一些\hfill命令：

\documentclass[a4paper,fleqn,demo]{cas-sc} % Remove the demo option in your real document.
\usepackage{natbib}
\usepackage{subcaption}
\begin{document}
\begin{figure}%
  \begin{subfigure}[b]{0.3\linewidth}\centering
      \includegraphics[width=\linewidth]{FE_CDF2.eps}
      \caption{FE grid }
      \label{fig:(a)}
  \end{subfigure}
  \hfill
  \begin{subfigure}[b]{0.3\linewidth}
    \includegraphics[width=\linewidth]{Daytown_CDF2.eps}
    \caption{Daytown grid }
    \label{fig:(b)}
  \end{subfigure}
\hfill
  \begin{subfigure}[b]{0.3\linewidth}
    \includegraphics[width=\linewidth]{EKPC_CDF2.eps}
    \caption{EKPC grid }
    \label{fig:(c)}
  \end{subfigure}
  \caption{CDF of daily MAPE on FE, Daytown, and EKPC grids data of USA for our proposed FCRBM based model and existing models (AFC-ANN, Bi-level, MI-ANN). }
  \label{fig_CDF_USA_Grid}
\end{figure}
\end{document}

附注：虽然文档内容不需要，但不包含包 natbib会导致以下错误消息：! Undefined control sequence. \@begindocumenthook ...\@afterindentfalse \bibsep=0pt\gdef \bibfont {\fonts...

Answer 2

该subfigure包已过时；无论如何，它的语法完全不同，并且需要命令\subfigure而不是\begin{subfigure}。

环境subfigure由包提供subcaption。

\documentclass[a4paper,fleqn]{cas-sc}
\usepackage{booktabs,siunitx,natbib}
\usepackage{subcaption}
\usepackage{graphicx}


\begin{document}

\begin{figure}[pos=!htbp]
\begin{subfigure}[b]{0.32\textwidth}
\includegraphics[width=\textwidth]{example-image}
\caption{FE grid}\label{fig:(a)}
\end{subfigure}\hfill
\begin{subfigure}[b]{0.32\textwidth}
\includegraphics[width=\textwidth]{example-image}
\caption{Daytown grid}\label{fig:(b)}
\end{subfigure}\hfill
\begin{subfigure}[b]{0.32\textwidth}
\includegraphics[width=\textwidth]{example-image}
\caption{EKPC grid}\label{fig:(c)}
\end{subfigure}

\caption{CDF of daily MAPE on FE, Daytown, and EKPC grids data of USA for our proposed FCRBM based model and existing models (AFC-ANN, Bi-level, MI-ANN).}
\label{fig_CDF_USA_Grid}
\end{figure}

\end{document}

请注意，该类需要不同的语法来指定图形的定位。

不要以空格结束标题。还请避免使用空格，scale因为您将无法控制宽度；最好使用width。
