Bidirectional electric vehicle (EV) charging is a technology that is gaining rapid popularity due to its ability to provide economic and environmental benefits to both EV owners and power system operators (PSOs). Using the EV as a flexible source of energy, an EV owner can provide power to homes/buildings, or even participate in grid services such...

The urgent transition towards electric vehicles (EVs) may potentially result in expensive capacity upgrades for power system operators (PSOs), however, the recent uptake in bidirectional EV charging, often referred to as "Vehicle to Everything" (V2X), may defer this need while simultaneously generating revenue for participating EV owners. Yet, ther...

The successful implementation of multi-agent control strategies (MAS) within smart grid applications is heavily reliant on communication frameworks that enable robust inter-agent messaging. In this regard, a promising communication framework is Data Distribution Service (DDS), which is fully distributed, enables low-latency messaging, and provides...

Distributed voltage regulation schemes within active distribution networks (ADNs) are receiving plenty of attention because they reduce latency bottlenecks. However, previous schemes often employ a trusted moderator to govern agent communication, thereby exposing potential trust issues that may affect agent performance. Blockchain technology can av...

Residential energy trading systems (RETS) enable homeowners with distributed energy resources (DERs) to participate in virtualized energy markets that have the potential to reduce the peak demand of residential communities. Blockchains are key enablers of RETS, by virtue of providing a decentralized, self-governed network that mitigates concerns re...

Transactive Energy Systems (TES) are modern mechanisms in electric power systems that allow disparate control agents to utilize distributed generation units (DGs) to engage in energy transactions and provide ancillary services to the grid. Although voltage regulation is a crucial ancillary grid service within active distribution networks (ADNs), pr...

This paper proposes an optimal zone clustering algorithm of islanded microgrids (IMG) based on supply adequacy taking into account the dynamic performance of distributed state estimation units. The IMG is partitioned into several localized, yet coupled zones, where each zone is responsible for its local state estimate and performs data fusion to re...

This paper proposes a nonlinear particle filter (PF) method for dynamic state estimation in droop-controlled islanded microgrids (IMGs). The PFs are normally applied to systems that (1) have highly nonlinear system dynamics, and (2) do not require the additive process or observation noise to be Gaussian. This flexibility allows the PFs to handle no...

The paper develops a fusion-based, reduced order, distributed implementation of the unscented particle filter (FR/DUPF) for state estimation in complex nonlinear electric power grids (EPG). Based on partitioning the overall EPG system into n localized but dynamically coupled subsystems, the near-optimal FR/DUPF provides a computational saving of up...
