Adaptive Control of Distributed Energy Resources for Distribution Grid Voltage Stability
Daniel Arnold, Shammya Saha, Sy-Toan Ngo +5
Volt-VAR and Volt-Watt functionality in photovoltaic (PV) smart inverters provide mechanisms to ensure system voltage magnitudes and power factors remain within acceptable limits.…
Lyapunov Stability of Smart Inverters Using Linearized DistFlow Approximation
Shammya Shananda Saha, Daniel Arnold, Anna Scaglione +4
Fast-acting smart inverters that utilize preset operating conditions to determine real and reactive power injection/consumption can create voltage instabilities (over-voltage, volt…
A Secure Distributed Ledger for Transactive Energy: The Electron Volt Exchange (EVE) Blockchain
Shammya Saha, Nikhil Ravi, Kari Hreinsson +3
The adoption of blockchain for Transactive Energy has gained significant momentum as it allows mutually non-trusting agents to trade energy services in a trustless energy market. R…
Deep Reinforcement Learning for DER Cyber-Attack Mitigation
Ciaran Roberts, Sy-Toan Ngo, Alexandre Milesi +7
The increasing penetration of DER with smart-inverter functionality is set to transform the electrical distribution network from a passive system, with fixed injection/consumption,…
Integrating Hardware Security into a Blockchain-Based Transactive Energy Platform
Shammya Shananda Saha, Christopher Gorog, Adam Moser +2
This applied research paper introduces a novel framework for integrating hardware security and blockchain functionality with grid-edge devices to establish a distributed cyber-secu…
Keeping Them Honest: a Trustless Multi-Agent Algorithm to Validate Transactions Cleared on Blockchain using Physical Sensors
Nikhil Ravi, Shammya Saha, Anna Scaglione +1
In recent years, many Blockchain based frameworks for transacting commodities on a congestible network have been proposed. In particular, as the number of controllable grid connect…
