PROJECT TITLE :

Utilization Improvement of Transformers Using Demand Response

ABSTRACT:

Due to load growth, aging infrastructure, and a competitive atmosphere, innovative solutions are needed by electrical utilities to reinforce the employment of transformers that are cost intensive. This paper proposes a demand response optimization model based mostly on transformer hottest-spot temperature. The optimization model quantifies the improvement of transformer utilization through DR. The proposed model is applied to a typical Finnish residential primary and secondary distribution transformers for case studies of load with and without DR. The results show that the loading on the transformers can be significantly increased without sacrificing the life of transformers. The gain in utilization depends on the DR capability of the load. Significant financial advantages can be achieved with the deployment of the proposed model in a real system.
