A Deep Game Bidding Model and Practice of Electricity Market

Aiming at the problems such as unclear price signals and insufficient competition in the current power market, a deep game bidding model for supply and demand sides is proposed based on the listing trading mechanism. Supply and demand sides both list and delist within the limits of price through three stages including information publicity, power plants listing and power consumers delisting, power consumers listing and power plants delisting, then electricity prices are cleared according to the delisting price. The accumulated delisting capacity limit is unconstrained. By optimizing the order of transactions in the two trading phases, the publicity volume of market participants is taken as the upper limit of the transaction volume of the entire two-way listing transaction. Flow charts of the transaction organization and the market clearing calculation method are also given. Not only can the bidding model stimulate the reasonable offer of both supply and demand, but also it can realize the organic cooperation of trading price and amount, reduce trading risk, expand trading power and improve the efficiency of resource allocation. The operation of the Yunnan electricity market has confirmed the rationality, effectiveness and practicability of the bidding model.
