Safe and Private Forward-Trading Platform for Transactive Microgrids

Abstract

Transactive microgrids have emerged as a transformative solution for the problems faced by distribution system operators due to an increase in the use of distributed energy resources and rapid growth in renewable energy generation. Transactive microgrids are tightly coupled cyber and physical systems, which require resilient and robust financial markets where transactions can be submitted and cleared, while ensuring that erroneous or malicious transactions cannot destabilize the grid. In this paper, we introduce TRANSAX, a novel decentralized platform for transactive microgrids. TRANSAX enables participants to trade in an energy futures market, which improves efficiency by finding feasible matches for energy trades, reducing the load on the distribution system operator. TRANSAX provides privacy to participants by anonymizing their trading activity using a distributed mixing service, while also enforcing constraints that limit trading activity based on safety requirements, such as keeping power flow below line capacity. We show that TRANSAX can satisfy the seemingly conflicting requirements of efficiency, safety, and privacy, and we demonstrate its performance using simulation results.CCS Concepts: • Computer systems organization → Embedded and cyber-physical systems; • Security and privacy;

New Market Model with Social and Commercial Tiers for Improved Prosumer Trading in Microgrids

“…From other perspectives, the prosumer surplus trading process based on the specific transactive energy microgrids are examined by the researchers in [58][59][60]. The prosumers' aggregation to one group with the same interest based on virtual microgrids is analyzed by the authors in [61] for bill cost reduction as a particular energy poverty mitigation or social welfare.…”
