Study on Bidding Mechanism Design and Clearing Mode under Safety Regulation Mode

With the access of large-scale new energy, the external cost of new power system security has increased significantly, and the situation of power grid security and supply is increasingly severe. In this context, this paper draws lessons from the balanced market trading model in Europe, proposes the balance regulation service, improves the transaction and clearing mechanism of the current day-ahead market, establishes the joint operation mechanism of new energy participating in electric energy-balance regulation service, and realizes the internalization of security external costs., Based on the probability of balance principle, establish electric energy and balance regulation service joint clearing model, soft electric energy trading curve, avoid high proportion of new energy access system down the problem of insufficient ability, at the same time through the market, accurately meet the demand of each time balance regulation service, greatly improve the security and economy of the overall clearing results, meet the new energy access under the power system security for demand.
