Presented by Kwami Senam Sedzro Master’s Eng. Electrical Engineering Master’s Research Engineering Sciences/EE Master’s Eng. ESE Student / Fulbright Scholar Results Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities For 1 day:

Results: DAM/RTM Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities

Results: DART/RTM Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities

Results : Revenue per Storage capacity – 10, 20 & 30 MWh Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities

Results : Revenue per Storage capacity Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities As storage capacity increases, the DAM strategic bidding profit tends to catch up with the mixt (RT-DA) bidding

Future Work Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities Integrate in the analysis: Stochasticity of Wind power generation o account for intertemporal probability distribution o compare online decision vs ex-ante strategy Lifecycle cost evaluation of energy storage Grid stability constraints

Conclusion Optimization of Wind and Storage Dispatch for Enhanced Market Opportunities This project resulted in the development of algorithms that maximize wind farms’ revenue by optimally dispatching wind and energy storage systems on daily basis, based on energy market prices and wind power forecasts The revenue as a function of the storage capacity is presented. Wind power producers will be able to have a significant share even in the day-ahead market With more data (at least 10 years), we can build a RTMP/DAMP model in order to predict when to bid into the DAM or into the RTM The extra $ gained in the DAM and the grid reliability made possible by this project are reasons for its implementation
