Intermittence is one the main obstacles in wind power penetration, due to imbalance charges set by market prices. To cope with this drawback, demand-side participation has been proposed as a good complement that can handle positive and negative imbalances. This study suggests an offering optimisation model for aggregated wind power and flexible loads in day-ahead electricity markets. Flexible load as a storage unit can either cover wind power imbalances or recover itself according to electricity price and load curve during various hours. The proposed offering model is compared with the disaggregated operations of wind and demand response with satisfactory results.
