Implementing multi-settlement decentralized electricity market design for transactive communities with imperfect communication.

The ubiquitousness of the low cost Information & Communication Technologies (ICT) provides strategic opportunities for the "prosumers", customers that both consume and produce energy, to have a more proactive role in system operation. From an operational perspective, though, this creates additional challenges in managing power distribution networks due to such active grid-edge systems with limited to no visibility or control by the utilities. Transactive Energy (TE) has been emerging as a key enabler towards efficiently coordinating prosumers through market based constructs thereby encouraging more consumer-centric economies. However, communication-based controls are susceptible to losses in information or message delays, potentially de-synchronizing solutions. This work presents a transactive implementation of a community-based electricity market design based on a multi-settlement decentralized coordination strategy. The coordination mechanism presents an algorithm that provides robustness to communication delays. A co-simulation framework is developed for evaluating the proposed market structure with high-fidelity models and delay-prone communication systems. Case studies on the IEEE-123 node test system demonstrate the feasibility of the proposed community-based TE architecture to collaboratively operate prosumer-communities as grid-edge systems and quantifies their potential benefits. • A decentralized transactive architecture is proposed for community-centric markets. • A multi-settlement (DA & RT) market is designed for optimal coordination. • The proposed market in implemented through a high-fidelity co-simulation framework. • Impacts of non-ideal communication system on the market mechanism is demonstrated. • A methodology has been developed for ensuring robustness to communication delays.
