Summary: The article compares discrete storage model (DSM) and continuous storage model (CSM) in power system planning and finds that DSM provides more reasonable storage sizing decisions than CSM. However, when considering DSM in interval optimization, the discrete status variables and temporal coupling pose challenges. To address this, a tailored interval optimization approach is proposed to incorporate both DSM and renewable energy uncertainty in generation expansion planning (GEP). The approach covers all worst cases in a given uncertainty set without requiring iterations and also introduces a bi-interval policy to balance investment cost and system security.

Summary: For investment decision making and market modeling in the energy sector, it is important to consider a wide range of uncertainties. The difference between deterministic and stochastic solutions increases non-linearly when uncertainties across multiple inputs are combined. Combining uncertainty sources by adding a limited number of scenarios to multiple sources of uncertainty outperforms adding additional scenarios to any individual source of uncertainty.

Summary: Spatially highly-resolved capacity expansion models are often simplified to a lower spatial resolution due to computational limitations, which may lead to infeasible system representations. This article addresses the challenge of disaggregating and assessing the feasibility of highly-resolved models. Different methods, such as uniform distribution and re-optimization, are proposed to disaggregate the results. The feasibility is evaluated through operational dispatch, showing that even state-of-the-art reduced models for Europe still result in load-shedding.
