POWER DISTRIBUTION PLANNING - A REVIEW OF MODELS AND ISSUES

Power distribution planning is a complex task in which planners must e nsure that there is adequate substation capacity (transformer capacity ) and feeder capacity (distribution capacity) to meet the load demands . Decisions such as allocation of power flow, installation of feeders and substations, and procurement of transformers are costly ones which must be evaluated carefully. This paper provides a review of research problems as well as models related to the planning of substations and /or distribution feeders. Following a general discussion, we review ex isting research work under two major groups: planning under normal con ditions, and planning for emergency. A discussion on relevant research opportunities is included.
