摘　　要：目前,我国电力市场模式是暂不包括用户侧市场的单边电力市场,市场中的发电商会利用各自的市场力来抬高电价,获取超额利润,而发电侧市场中过高的电价常常会导致电力公司经营困难,进而导致整个电力市场的崩溃。文中基于经济学中的社会效益理论,提出了一种应用于单边电力市场的价格控制模型来控制市场电价,以确保市场平稳高效地运行。为了检验所提出的价格控制模型的有效性,采用协同进化算法对发电市场的运营进行了模拟,模拟结果表明所提出的价格控制模型行之有效。At present, the electricity market of China is a unilateral market excluding retail market. This kind of market with fixed load demand is imperfect. The power companies may use the market power to manipulate the market price and earn more profits. However, the exorbitant price of the generation market may lead to the bankruptcy of power companies and the breakdown of the whole electricity market. Based on the theory of social welfare of economics, a price control model is proposed to apply to this unilateral electricity market to control the electricity price, and insure the stable and highly efficiently running of the electricity market. In order to prove the effectiveness of the proposed model, an artificial intelligence method is adopted to simulate the operation of the market based on the evolutionary game and cooperative co-evolutionary algorithm. The simulation results show that the proposed price control model is effective.
