Reinforcement Learning for Public Safety Power Shutoffs Under Decision-Dependent Uncertainty and Nonlinear Wildfire Ignition Models
Prasanna Raut, Chaoyue Zhao, Alexandre Moreira
Power grid infrastructure is an increasingly significant source of wildfire ignitions and poses severe risks to communities in fire-prone regions. Public Safety Power Shutoffs (PSP…
A Markov Decision Process Framework for Enhancing Power System Resilience during Wildfires under Decision-Dependent Uncertainty
Xinyi Zhao, Prasanna Raut, Chaoyue Zhao +1
Wildfires pose an increasing threat to the safety and reliability of power systems, particularly in distribution networks located in fire-prone regions. To mitigate ignition risk f…
From Net Load Modifiers to Firm Capacity: The Role of Distributed Energy Resources in Resource Adequacy
Yujia Li, Alexandre Moreira, Miguel Heleno
Distributed energy resources (DERs) such as rooftop solar, batteries, demand response, and electric vehicles can contribute to power system reliability, yet their performance is di…
Time Window-Based Netload Range Cost Curves for Coordinated Transmission and Distribution Planning Under Uncertainty
Yujia Li, Alexandre Moreira, Miguel Heleno
Mechanisms to coordinate transmission and distribution planning should be regulatory compliant and keep the spheres of DSO and TSO decisions separate, without requiring disclosure…
Dynamic Transmission Line Switching Amidst Wildfire-Prone Weather Under Decision-Dependent Uncertainty
Juan-Alberto Estrada-Garcia, Ruiwei Jiang, Alexandre Moreira
During dry and windy seasons, environmental conditions significantly increase the risk of wildfires, exposing power grids to disruptions caused by transmission line failures. Wildf…
State-wise Economic Viability of Long-Duration Energy Storage Systems in the United States
Alexandre Moreira, Patricia Silva, Miguel Heleno +1
Long-duration energy storage (LDES) assets can be fundamental resources for the next-generation power systems. However, LDES technologies are still immature and their future techno…
A Modeling Framework for Equitable Deployment of Energy Storage in Disadvantaged Communities
Miguel Heleno, Paul Lesur, Alexandre Moreira
This paper provides an analytical framework to incorporate the deployment of behind-the-meter energy storage coupled with rooftop solar, and their associated revenue streams, in th…
Decision-Dependent Uncertainty-Aware Distribution System Planning Under Wildfire Risk
Felipe Piancó, Alexandre Moreira, Bruno Fanzeres +3
The interaction between power systems and wildfires can be dangerous and costly. Damaged structures, load shedding, and high operational costs are potential consequences when the g…
Netload Range Cost Curves for a Transmission-Aware Distribution System Planning under DER Growth Uncertainty
Samuel Cordova, Alexandre Moreira, Miguel Heleno
In the face of a substantial and uncertain growth of behind-the-meter Distributed Energy Resources (DERs), utilities and regulators are currently in the search for new network plan…
Assessing Costs of Community Solar Integration via Optimal Distribution Grid Expansion
Miguel Heleno, Alan Valenzuela, Alexandre Moreira +1
This paper presents a comprehensive analysis of distribution grid upgrades costs necessary to integrate Community Solar (CS) projects. The innovative methodology proposed for this…
Boundary Technology Costs for Economic Viability of Long-Duration Energy Storage Systems
Patricia Silva, Alexandre Moreira, Miguel Heleno +1
The urgent need for decarbonization in the energy sector has led to an increased emphasis on the integration of renewable energy sources, such as wind and solar, into power grids.…
