Supporting Energy Transition in Transmission Systems: An Operator’s Experience Using Electromagnetic Transient Simulation
The electric power industry is faced with the challenges of mitigating climate change, maintaining low electricity prices, and satisfying high reliability requirements for power supply. The increased application of power electronics devices is the inevitable result of the changes being experienced by the system. Careful analysis is required to install and operate power electronics devices. This article describes the use of electromagnetic transient (EMT) simulation on the French transmission grid to meet these new challenges in the context of energy transition.

Resilience Assessment of Distribution Systems Integrated With Distributed Energy Resources
The resilience of electric systems is receiving growing attention due to their increased vulnerability to infrastructure damages and widespread outages from frequent extreme climactic conditions attributed to global warming effects. Resilience evaluation methods should recognize the uncertainties and correlations in the performance variations of different types of energy resources, load characteristics, extreme events and their impacts on the grid elements.

Stochastic Generation Capacity Expansion Planning Reducing Greenhouse Gas Emissions
With increasing concerns about greenhouse gas emissions, a least-cost generation capacity expansion model to control carbon dioxide (CO 2) emissions is proposed in this paper. The mathematical model employs a decomposed two-stage stochastic integer program. Realizations of uncertain load and wind are represented by independent and identically distributed (i.i.d.) random samples generated via the Gaussian copula method. Two policies that affect CO 2 emissions directly and indirectly, carbon tax and renewable portfolio standard (RPS), are investigated to assess how much CO 2 emissions are expected to be reduced through those policies.
