  Managing Demand Response and Renewables in Smart Grids  
(Lectures/Talks)

Nikolaos Gatsis
Assistant Professor, Dept. of Electrical and Computer Engineering,
UTSA

Abstract:
Demand response based interaction of end-users with the power network, and the high penetration of renewable energy sources, are two key ingredients of the smart grid vision. The first part of the talk considers demand response in a multi-residence setup. Each residential end-user has loads whose power consumption can be adjusted; however, various operational constraints must be respected, and operation away from user-specified levels may result in user dissatisfaction. Examples of adjustable loads are air-conditioners or plug-in (hybrid) electric vehicle battery charging. A demand response management scheme to jointly minimize the electricity provider cost and the total user dissatisfaction while respecting user privacy will be presented. The scheme relies on message exchanges between the utility company and the user smart meters through the Advanced Metering Infrastructure (AMI), and is resilient to lost AMI messages. Such can occur due to communication errors or cyber-attacks at the AMI network. The second part of the talk focuses on microgrids featuring distributed generation from renewable and conventional energy sources, distributed storage, and adjustable loads. To address the intermittency of renewable energy sources, novel robust or stochastic energy management methods to maintain the supply-demand balance and minimize the microgrid net cost will be presented.
