计及碳排放成本的风光燃储综合能源系统规划

Study on Optimization of Wind,Solar,Fuel and Storage Integrated Energy System Taking into Account the Cost of Carbon Emissions

构建了一套耦合风光燃储网的冷、热、电三联供综合能源系统,以系统经济性和环境效益为优化目标对系统的设备和参数进行优化研究,得出了现行约束条件下的最优系统配置。结果表明:5种系统中,“风-光-燃-储-网”系统的年CO_(2)排放量和系统总成本均最低;“风-光-储-网”系统消纳可再生能源的能力最佳,可再生能源渗透率为69.93%,但总成本为“风-光-燃-储-网”系统的159%;光伏价格和碳税价格与年CO_(2)排放量呈反比,且当光伏降价比例达到40%后,其对年CO_(2)排放量的限制作用不再突出。

A set of integrated energy system coupled with wind,solar,fuel,storage and network was constructed.With the optimization objectives of system economy and environmental benefits,the equipment and parameters of the system were optimized to obtain the optimal system configuration under current constraints.Results show that among the five systems,the annual CO_(2) emission and total system cost of the wind,photo,combustion,storage and network system are the lowest.The wind,light,storage and network system has the best ability to absorb renewable energy,and the penetration rate of renewable energy is 69.93%,but the total cost is 159%of the wind,light,combustion,storage and network system.Photovoltaic prices and carbon tax prices are inversely proportional to annual CO_(2) emissions,and when the photovoltaic price reduction ratio reaches 40%,its limiting effect on annual CO_(2) emissions is no longer prominent.
