Economical Unit Commitment Solutions Through Renewable Energy Management Centers for Reliable Integration of Large-Scale Renewable Energy Resources

摘要

This paper aims at achieving economical and secure commitment of conventional thermal power generating units in a power system integrated with renewable energy sources (RES) by harnessing the renewable energy generation potential to its maximum. The data forecasting tool of renewable energy management center (REMC) is used for closer prediction of RES availability which helps to achieve much improved unit commitment (UC) solution of conventional thermal units apart from intermittent nature of power output obtained from RES. Large-scale penetration of RES is achieved with the advancement in technology supports better optimization of economical dispatch and reduces the thermal plant running hours. This supports considerable reduction in fossil fuel requirements, carbon foot print, and green house emission, and causes lesser impact on global warming, climate change, and improves quality of atmospheric air. This paper analyzes present need of REMCs to integrate large-scale renewable into the grid and to reduce the RES curtailment due to poor prediction of RES availability.
