摘 要:作為電能供應(yīng)商和用戶之間的橋梁,零售商同時與供應(yīng)商和用戶進(jìn)行電能交易。在交易過程中,零售商的效益受到售電量和價格水平的影響。以零售商效益最大化為目標(biāo),建立新的電力市場模型,引入博弈競爭機(jī)制,建立基于收益和負(fù)荷均衡的伯川德模型和斯塔克爾伯格模型(Stackelberg 模型),并通過數(shù)值試驗分析兩種博弈模型下售電商的效益以及傳統(tǒng)用戶數(shù)量對零售商定價和效益的影響。

Abstract: Retailers will become a bridge between power suppliers and users, while trading with suppliers and users. In the course of the transaction, the retailer's benefits are affected by the electricity sales and price level. Aiming at the maximum of retailer's benefits, this paper established a new electricity market model and introduced a game competition mechanism. This paper established a Bertrand model and a Stackelberg model based on revenue and load balance. Through numerical experiments, the benefits of the electricity sellers under the two game models were analyzed, as well as the influence of the number of traditional users on the retailer's pricing and benefits.
Key words: power load; market model; Bertrand model; Stackelberg model
