针对丰富的合约交易形式将对电力市场产生重大影响的问题,基于Cournot模型建立了远期与现货市场的两阶段市场均衡模型,利用反向推导方法对模型进行了求解,通过比较电力市场环境下引入远期合约交易前后的电力需求弹性与供电量间的变化及市场雷纳指数的变化,分析了远期合约对市场效率的影响,并以内蒙古三个区域市场实际交易信息为例对模型进行了验证。结果表明,该模型合理、正确。
Aiming at the problem that the rich contract transaction will have a significant impact on the electricity market, a two-stage market equilibrium model of the forward and the spot market is established based on the Cournot model. The reverse derivation method is used to solve the model. By comparing the power market environment The paper introduces the changes of the electricity demand elasticity and the electricity supply before and after the forward contract transaction and the changes of the market Reynolds number. It also analyzes the impact of the forward contract on the market efficiency. Taking the actual transaction information of the three regional markets in Inner Mongolia for example, Verified. The result shows that the model is reasonable and correct.
