Effect of Environmental Temperature Rise on Optimal Places and Number of Distributed Generators

Optimally siting distributed generations (DGs) is regarded as one of the most effective mechanisms for loss mitigation on a distribution network. Power loss curtailment on distribution networks is a very essential in power system operation and management since it constitutes the major share of the overall power loss on power systems. Losses on power systems lead to exorbitant network operation costs as well as the distortion of the system’s voltage profile. In traditional DG placement, the optimal locations and the number of distributed generators are optimally determined for ensuring that losses are reduced to the barest minimum in order to meet the power demand of consumers. Load variation on distribution buses leads to different resultant losses in comparison with constant loads. Nevertheless, several proposed models for DG allocation problem ignored consumers’ load variability. While the selected few that considered load variation in their proposed models neglected the impact of ambient temperature change on electrical energy usage which influence appropriate places and DG number. Accordingly, the current study evaluates environment’s temperature change impact on DG allocation solutions to access environmental temperature change importance in loss optimization via DG placement. It is observed that ambient temperature variations significantly change the appropriate places and DG sources number.
