低碳化、清洁化是我国电力行业未来发展的方向。在新一轮电力体制改革的形势下,风电、光伏等可再生能源的接入以及碳排放交易制度的建立均将对电力市场的运行产生显著影响。为此,基于经典的古诺博弈竞争模型,对燃煤、燃气、水电、新能源(包括风电和光伏)等不同类型机组的运行特性,以及储能系统参与市场的运行方式进行了建模,在考虑不同类型机组碳排放特性与碳排放成本的基础上,构建了2层优化的电力市场出清均衡模型,并提出了相应的求解方法。最后,采用实际数据对电力市场的均衡状态进行了模拟计算,分析了碳排放成本对于电力市场均衡状态的影响。
Low-carbon, clean is the future direction of China’s power industry. In the new round of power system reform, access to renewable energy such as wind power and photovoltaic power and the establishment of a carbon emissions trading system will have a significant impact on the operation of the electricity market. Therefore, based on the classical Cournot game competition model, the operating characteristics of different types of units, such as coal, gas, hydropower, new energy (including wind power and photovoltaic), as well as the operation mode of energy storage system in the market are modeled. On the basis of considering the carbon emission characteristics and carbon emission cost of different types of units, a two-layer optimized equilibrium model of electricity market clearing is constructed and the corresponding solution method is proposed. Finally, the actual data is used to simulate the equilibrium state of electricity market, and the impact of carbon emission cost on the equilibrium state of electricity market is analyzed.
