Transactive Local Energy Markets Enable Community-Level Resource Coordination Using Individual Rewards

This journal publication delves into the heart of ALEX (Autonomous Local Energy eXchange), focusing on a key hypothesis: can ALEX align the interests of individual participants and grid stakeholders and foster the reduction of community level intermittence, even when each participant operates in self-interest and lacks shared information?

To find out, we compare ALEX against a set of baselines on the CityLearn2022 dataset.

Understanding the Baselines:

  • NoDERMS (Baseline): Represents the scenario without DERMS (Distributed Energy Resource Management System), reflecting the ‘passive’ end-user.
  • IndividualDERMS (Baseline): Illustrates the performance of a state-of-the-art DERMS that perfectly optimizes self-consumption, ramping rate, peak net load, and similar metrics on a building level.

 

What Does It Mean for You?

  • Reduced Infrastructure Stress: ALEX demonstrates a significant reduction in average daily energy import, peaks, and valleys, leading to lower utilization of grid infrastructure and higher hosting capacities.
  • Efficient Energy Shifts: ALEX’s ensures a smoother energy usage pattern within the community, reducing DER-related intermittence more effectively than state of the art DERMS.
  • Scalability: ALEX does not require excessive amounts of communication infrastructure to unlock its community-wide coordination.
