摘要: In order to comply with European emission goals, the role of accurate grid representation in energy system optimization is getting increasingly more important larger shares variable renewable energies. This paper compares transmission approaches using flow-based (FB) modelling Power Transfer Distributing Factor (PTDF) Net Capacity (NTC) models for investment optimization. The open-source model Balmorel was used investigate impact on results. Overall, electricity prices flattened a spatial level FB compared NTC. Additionally, change decision generation capacities identified. Locations newly installed lines and production sides are shifted furthermore slightly when representing AC-system its physics through modelling. However, rough subsequent clustering creates an uncertainty about overestimated line benefits Therefore, further studies needed accurately assess transition from current NTC methodology
