Bidding strategy of wind storage combined system participating in electricity-carbon combined market under double carbon target

Abstract

In the context of “30 60” double carbon target, the decarbonization of the power system is the key to the zero-carbon development of the whole society. The complementarity of energy storage and wind generation can effectively alleviate the uncertainty and volatility of renewable energy and promote zero-carbon energy integration. In this paper, an optimal bidding strategy for Wind Storage Combined System (WSCS) to participate in the electricity-carbon combined market is proposed Firstly, the market structure and market operation mode of China's current carbon trading market are introduced. On this basis, the trading methods, trading processes and clearance mechanisms of WSCS participating in the combined electricity-carbon market are analyzed. Secondly, based on the master-slave game, a two- layer bidding strategy model for WSCS to participate in the electricity-carbon combined market is proposed. Finally, through the example analysis, it is shown that the introduction of carbon trading mechanism has improved the competitiveness of WSCS in the electricity market on the one hand, and raised its own economic benefits by a notch; On the other hand, while increasing the total consumption of renewable energy, it reduces the total amount of regional carbon emissions.
