Dr. Jenny Riesz

Featured Speaker: Jenny Riesz, Manager of Operational DER Management, Australian Energy Market Operator (AEMO)

Webinar Abstract: The Australian National Electricity Market (NEM) is now operating in some periods with more than half of supply coming from distributed photovoltaics: customer rooftops. In some regions such as South Australia, the amount of generation from rooftops now exceeds the total demand for the region in some periods. This presentation will cover AEMO’s analysis to model and understand likely DER behaviors and power system operational limits when operating the power system under these novel very low demand conditions. This includes examining bulk rooftop PV behaviors in past power system incidents based on large novel datasets, development and validation of power system models to replicate these behaviors in power system studies, and analysis to assess power system limits under very low demand conditions.

About the Speaker: Dr. Jenny Riesz is the Manager of Operational DER Management at the Australian Energy Market Operator (AEMO), a team within AEMO’s Operations division that has responsibility for integrating Distributed Energy Resources (DER) into AEMO’s operational functions. This includes analyzing DER performance and behaviors during power system disturbances, development of new procedures and processes for operational management of Minimum System Load (MSL) periods, development and validation of power system models for assessing DER impacts on system security and power system limits, and uplift of operational technology to manage DER. Prior to this, Jenny was at the University of New South Wales (UNSW), doing research on 100% renewable power systems, and a consultant at ROAM Consulting, delivering analysis on renewable integration.

Moderator: Debbie Lew, Executive Director, ESIG
