Probabilistic load flow in microgrid assessment and planning studies

In this paper, probabilistic load flow technique is employed as a decision tool for the location of renewable energy generators within a micro-grid. The importance of probabilistic load flow within the micro-grid is first illustrated by comparing results from it with those from deterministic load flow. Probabilistic load flow is then employed as a tool in deciding the in-feed point for a proposed wind farm within a 22-bus simplified university network while considering two scenarios (peak load demand during winter examination and low load demand in summer holiday). The optimal wind farm location was decided based on three criteria; the voltage level on each substation, the line flow compliance and the total system losses.
