Abstract: To stabilize output variability of distributed renewable energy sources (RESs), integrating large-scale RESs is highly utilized, and aggregated RESs are treated almost as any other conventional generators in existing electricity markets. In this talk we first propose a coalitional framework to cope with the uncertainty of RESs when RES owners can participate in a wholesale electricity market as sellers, where a market operator financially penalizes RES owners for deviations between day-ahead and real-time markets. Our theoretical approach incentivizes participants in a coalition by mitigating penalty fees caused by renewable variability. Furthermore, we propose a bidding strategy called Gaussian residual bidding (GRB) to maximize a coalition gain of participants. We prove that the considered game is convex game when GRB is used for all participants. Our extensive simulations with real data demonstrate that the proposed bidding strategy combined with the coalitional framework outperforms other bidding strategies as well as non-coalition cases under various market scenarios. Our results exhibit the revenue of GRB is improved up to 200% compared to the existing empirical quantile bidding and forecast bidding strategies.
