% 潮流计算
[P,Q,V,theta] = powerflow(data,branch);

% 分区
partition = zeros(size(data,1),1);
for i=1:size(data,1)
    if V(i)<0.95
        partition(i) = 1;
    elseif V(i)>=0.95 && V(i)<=1.05
        partition(i) = 2;
    else
        partition(i) = 3;
    end
end

% 结果输出
fprintf('节点\t 电压幅值\t 相角\n')
for i=1:size(data,1)
    fprintf('%d\t %f\t %f\n',i,V(i),theta(i))
end

fprintf('\n节点\t 分区\n')
for i=1:size(data,1)
    fprintf('%d\t %d\n',i,partition(i))
end

这个程序首先定义了节点数据和支路数据，然后调用 `powerflow` 函数计算潮流，最后根据电压幅值将节点分成三个分区，并输出节点的电压幅值和相角，以及节点所属的分区。请注意，此程序仅用于演示，实际情况下需要根据具体的数据进行修改和优化。
