Adaptive Load Management: Scheduling And Coordination Of Demand Resources In Power Systems

Speaker: Doctor Jhi-Young Joo

Host Faculty: Professor Dariusz Czarkowski

Abstract

Demand response refers to techniques that manage end-users' electricity consumption in order to help the power system operate in a more cost-efficient and reliable way. It is becoming more important with increasing renewable and distributed energy resources incorporated into the system. Our proposed demand response framework, namely Adaptive Load Management, provides a comprehensive structure for demand response by formulating the complex power system objective as many sub-problems of diverse supply and demand entities in the system over multiple time horizons. In this talk, I will focus on the short-term scheduling of supply and demand resources, with an emphasis on managing flexible demand resources of small end-users. The difficulty of this problem comes from the uncertainty of loads and supply, limitations on communication and information exchange among a large number of supply and demand entities, and modeling different values of electric energy seen by diverse end-users/loads. I will address how we tackle these issues, and present simulation results that demonstrate how our methodology works.
