Help -- electric distribution network reconfiguration for loss reduction using ACS

Recently, I'm doing research based on electric distribution network reconfiguration for loss reduction using ACS, and my reference paper is the one from the link that i post. There are something about Table 1: Network Data that i don't understand. In the table, from third column to seventh column, what are those thing? What is V p.u , R p.u , X p.u , P MW , and Q MVAR ? What are they stand for ?

Please help...you can either read the uploaded file (which i get from IEEE website) or click the link ( if you have fast internet speed)
