Day-ahead Bidding Strategy of New Energy Power Station with Energy Storage Considering the Uncertainty of Wind and Solar Energy

With the proposal of dual-carbon target, the new power system presents the characteristic of high proportion of new energy penetration, and the volatility and uncertainty of new energy bring challenges to the stability and reliability of the energy system supply and demand, and at the same time is not conducive to the new energy as an independent subject of the market-oriented competition. Through the new energy distribution storage, in the form of joint participation in the day-ahead market for clearing, using stochastic optimization method to construct new energy output scenarios, day-ahead and real-time clearing tariff scenarios, using K-medoids method for the reduction of the typical scenarios, to new energy distribution storage power station system of the day-ahead revenue maximum as the goal, the establishment of the new energy joint energy storage to participate in the day-ahead market bidding strategy model. Finally, based on the historical data of a new energy power station and the spot market tariff data for example analysis, the results verify the effectiveness of the bidding strategy model.
