Climate-combined energy modelling approach for power system planning towards optimized integration of renewables under potential climate change- The Small Island Developing State perspective

While high renewable electricity targets are feasible under current climatic conditions, planning the power sector from a long-term perspective requires great precaution, given the strong dependency of renewable energy po-tential on climate and potential future changes. Power balance optimization modelling is a powerful tool for adequate power system (contingency) planning, and informed decision making in future perspective. This is demonstrated based on a case study of Suriname, considering scenario simulations and impact assessments for the 2030-2040 time horizon, for multiple load and climate projections. The recently developed REVUB modelling approach is utilized, which facilitates hourly-to-multiannual simulations, the latter being important for inter-annual variability assessments, and key for climate impact studies. Our results show that Suriname has an optimized renewable electricity share potential ranging from 50% to 90% under the considered future sce-narios based on complementary exploitation of hydro, wind and solar power resources.
