AI reasoning in math and coding: a stochastic generation-expansion solver
Introduction AI reasoning in mathematics For most of the deep-learning era, the relationship between large language models and mathematics was uneasy: systems that excelled at natural-language generation remained unreliable on multi-step reasoning and formal mathematics. That changed rapidly after 2024, as frontier systems reached Olympiad-level performance and began integrating directly with formal verification environments such […]

Planning under uncertainty: how NWPCC is preparing the Pacific Northwest for the energy transition
The Northwest Power and Conservation Council (NWPCC) is a U.S. interstate agency responsible for developing a regional power plan for the Pacific Northwest. Every few years, the Council produces a comprehensive plan that sets the direction for how the region should meet its future electricity needs over a 20-year horizon, balancing cost, reliability, environmental policy, […]
Quantifying the value of transmission flexibility: the HVDC link upgrade in New Zealand
Introduction Transmission infrastructure plays a central role in enabling modern power systems to operate efficiently under increasing uncertainty. In hydro-dominated systems with geographically concentrated resources, transmission capacity is particularly valuable because it allows energy to move between regions with different supply and demand characteristics. New Zealand is a clear example of this dynamic. The country’s […]
Why renewable uncertainty matters: evidence from brazil’s operation planning
Introduction Many power systems around the world are being reshaped by the energy transition. Wind and solar are scaling faster than any other technologies in modern electricity history, changing not only the generation mix but also the nature of system operation. As non-dispatchable resources take a larger share of supply, variability becomes a structural feature […]
Economic impact assessment of hydraulic operating constraints in brazilian hydropower plants
Context The Brazilian power matrix is predominantly composed of hydroelectric plants, which are responsible for most of the country’s electricity generation. The National Electric System Operator (ONS) coordinates and controls the operation of the National Interconnected System (SIN). To ensure safe and economic operation, it is essential to consider the operational limitations of these plants, […]
Optimal sizing and assessment of battery energy storage systems
The increasing integration of variable renewable energy sources introduces new operational challenges for power systems, particularly in terms of flexibility, reliability, and economic efficiency. In this context, battery energy storage systems (BESS) are becoming a promising technology, as they can contribute to meeting these requirements by providing services such as energy arbitrage, operating reserve, and […]
Energy storage for flexibility and reliability in interconnected and isolated systems
The Role of Storage in Energy Transition The Brazilian power sector is undergoing a profound transformation driven by the rapid expansion of variable renewable energy (VRE) and ambitious decarbonization targets. Although the country’s electricity matrix has historically been dominated by hydropower, the accelerated integration of wind and solar has introduced significant operational challenges to the […]
PSR User Meeting 2026: Where the next questions in energy analytics take shape
For more than two decades, PSR’s User Meeting has served as a forum for technical exchange among professionals engaged in energy planning, system operation, and analytical model development. Over time, however, its role has become broader than that of a conventional user event. As the sector has grown more complex, the meeting has increasingly become […]
