The penetration of distributed energy resources in the power system is constantly increasing.Establishing local electricity markets will help promote local accommodation and ensure the safe,stable,and economical operation of power systems with a high proportion of distributed energy resources.This paper proposes a local electricity market mechanism based on a combined clock auction,comprising three phases:the clock round,the complementary round,and settlement.In the clock round stage,an iterative clearing mechanism of"pricing by the market operator and decentralized optimal quantity bidding by market participants"is designed.A local price adjustment model incorporating the idea of fusion momentum method is introduced to transmit market dynamic information to aggregators through local price iteration,thereby reducing clearing uncertainty and trading risks.In the complementary round stage,a sealed-bid model considering behavioral constraints on bidding is developed to lower the bidding difficulty for aggregators.It is proven that the pre-cleared results of the clock round represent the optimal allocation with sealed bids in the complementary round.In the settlement stage,a settlement mechanism based on VCG-nearest payment is adopted to ensure that settlements satisfy core payment constraints,enhance market stability,and incentivize truthful bidding by market participants to a certain extent.Case study results demonstrate that the proposed market mechanism can effectively guide the local balancing of distributed energy resources and improve the economic efficiency of system operation.
