电-碳耦合市场的推测变差均衡
Conjectural Variation Equilibrium in Electricity-Carbon Coupling Markets
摘要
Abstract
With the application of the carbon-emission cap-and-trade mechanism,electricity producers have coupled the electricity market and carbon-emission market,which operate independently,due to their electricity production functions and carbon-emission characteristics.First,in order to show how each market agent in electricity-carbon coupling markets exercises market power and influences market prices in an oligopolistic environment,the conjectural variation coefficient is used to describe its strategic behavior,and a conjectural variation equilibrium model for electricity-carbon coupling markets is established.Then,starting from the definition,it is proved that the essence of the carbon-emission price in the market equilibrium solution is the dual multiplier of the carbon-emission cap balance constraint,reflecting its volatility characteristics determined by the supply and demand of carbon-emission cap.Finally,numerical results from different scenarios in the IEEE 9-bus test system are compared to demonstrate the impact of factors such as transmission line congestion,market competition modes,generation cost,and carbon-emission cap on the market equilibrium.And the incentive effect of the carbon-emission cap-and-trade mechanism on the renewable energy generation and its control effect on total carbon emissions are illustrated taking the actual Gansu power system in China as an example.关键词
