考虑碳交易影响风电消纳的综合能源系统优化运行

Optimal scheduling of integrated energy system considering impact of carbon trading on wind power consumption

针对综合能源系统低碳性和经济性之间的矛盾,在综合能源系统规划中引入电转气和电锅炉设备,通过增加多能互补耦合提高风电消纳率;然后在运行调度环节引入阶梯型碳交易进一步加强风电消纳能力,搭建了以运行成本、维护成本和环境成本之和最小为目标函数的综合能源系统优化运行模型;最后利用粒子群优化细菌觅食算法对构建的4种典型场景进行优化运行求解,分析了不同碳交易价格对能量转换组件运行结果的影响。结果显示:考虑碳交易的综合能源系统可有效提高系统风电消纳能力,能够兼顾经济性和低碳性。

Development of decarbonized electric power is an inevitable trend to meet the requirement of carbon peak and carbon neutral.In order to resolve the conflict between low carbon and economic consideration of the integrated energy system(IES),this paper introduced the power-to-gas(P2G)and electric boiler in the electric power plant planning.As a result,multi-energy complementary coupling rate was increased to improve wind power penetration.Furthermore,stepped-type carbon trading was introduced in the modelling of operation scheduling.Furthermore,an optimal operation model of the integrated energy system established as the objective function was minimal sum of operation cost,maintenance cost and environmental cost.At last,biomimicry of bacterial foraging-particle swarm optimization was employed to evaluate the effectiveness of optimized model and the influence of different carbon trading prices on the operation results of energy conversion modules.Result shows that proposed optimized model considering carbon trading can effectively improve wind power penetration and can balance between economic and environmental consideration.
