Demand Response Management by Rolling Unit Commitment for High Renewable Energy Penetration

We present an efficient demand response formulation embedded in a short-term power system scheduling framework suitable to cope with increasing renewable energy injections. The proposed framework comprises a real time unified unit commitment-economic dispatch model coupled with a generic model for responsive residential, commercial and industrial loads. In this way, a more efficient utilization of the demand response resources is achieved, since their balancing energy and reserve schedule is frequently refined based on updated system conditions. Finally, we perform yearly simulations of a modified Generation System of Greece to investigate the operational value of demand response.
