基于实验经济学的广东月度竞价分析

Analysis on Monthly Electricity Bidding of Guangdong Based on Experimental Economics

基于国内电力市场交易现状,应用实验经济学的方法对电力市场出清价格的影响因素进行研究。首先通过对实际的电厂竞价成本进行分析,确定其成本模型;之后通过搭建电力市场模拟竞价平台的方式,对不同供需比下的电力市场进行双边竞价实验仿真,以验证供需比对市场出清价格的影响。通过设立不同供需比的实验,依靠实验过程的观察与对实验结果的分析,发现市场供需比对电力市场的出清价格会产生明显影响。该方法采用模拟竞价方式,可排除实验环境中的非实验因素干扰。

On the basis of status quo of electric power market trade in domestic, this paper uses the experimental economics method to study influencing factors on clearing prices. First, it analyzes actual bidding costs of power plants and determines the cost model. Then, it builds a simulated bidding platform of the electric power market and makes experimental simulation on bilateral bidding of the electric power market under different supply and demand ratio so as to verify effect of supply and demand ratio on clearing prices. By means of setting different experiments on supply and demand ratios and according to ob- servation on experimental process and analysis on experimental results, it discovers that supply and demand ratio of the mar- ket has an obvious influence on clearing prices. By adopting a way of simulated bidding, this method can remove non-experi- mental interferences in the experimental environment.
