Temperature-dependent Radial Power Flow with Distributed Generation

Abstract

This paper proposes the Temperature-BFS method that apply the backward-forward sweep considering temperature of the distribution system conductors. Distributed generation should be considered in distribution system studies. Therefore, the Temperature-BFS method was used with exhaustive search for optimal allocation of distributed generation. The aim is to calculate the losses in the electrical system under the environmental conditions, such as, wind speed, ambient temperature and solar radiation. This methodology was applied to the 34-bus, 70-bus and 126-bus radial systems considering 1 and 2 distributed generation. It was observed an increase of 8% to 13% in the calculated losses by the Temperature-BFS algorithm.
