Market Equilibrium Based on Cloud-edge Collaboration

Market participants can only bid with lagged in-formation disclosure under the existing market mechanism,which can lead to information asymmetry and irrational market behavior,thus influencing market efficiency.To promote rational bidding behavior of market participants and improve market efficiency,a novel electricity market mechanism based on cloud-edge collaboration is proposed in this paper.Critical market information,called residual demand curve,is published to market participants in real-time on the cloud side,while participants on the edge side are allowed to adjust their bids according to the information disclosure prior to closure gate.The proposed mech-anism can encourage rational bids in an incentive-compatible way through the process of dynamic equilibrium while protecting participants'privacy.This paper further formulates the math-ematical model of market equilibrium to simulate the process of each market participant's strategic bidding behavior towards equilibrium.A case study based on the IEEE 30-bus system shows the proposed market mechanism can effectively guide bidding behavior of market participants,while condensing exchanged information and protecting privacy of participants.
