Geographical Optimization of Renewable Energy Portfolios With Regards to Output Risks in New York State Independent System Operator (NYISO)

摘要

In 2016 the New York State Public Service Commission announced an ambitious mandate: 50% of New York's electricity would need to come from renewable energy sources by 2030. Making Variable Renewable Energy (VRE) output fluctuations less pronounced is one of the ways to achieve the state's policy. This project proposes a simple retrospective simulation based on the established correlations between wind speeds and solar insolation in the region, as well as among the corresponding energy outputs. Based on the conducted analysis, both positive correlations between wind energy outputs across the region and negative correlations between solar PV and wind outputs were established. Those results allowed to run a simulation which let to some prominent findings: without altering the total energy output (-0.02% change), the standard deviation of the geographically optimized portfolio decreased by 5.5%.
