为了提高系统能源利用率,减少碳排放,提出一种考虑碳排放与变工况模型的综合能源系统多目标优化调度方案。根据各供能设备在不同负荷率以及外界因素影响下的输入输出特性建立相关的变工况模型,考虑碳排放成本并建立以系统运行成本最小、能源利用率最大为目标函数的优化调度模型,并基于MATLAB平台采用Yalmip+Gurobi工具箱对所建立的优化调度模型进行求解。仿真结果表明,建立的优化调度模型可以达到节能减排的效果,综合能源系统在碳排放成本以及变工况特性的约束下,能够实现高效、经济的运行。

A multi-objective optimal scheduling scheme of integrated energy system in view of carbon emission and variable working condition model is proposed to increase system energy efficiency and reduce carbon emission. First, relevant off-design models are established according to input and output characteristics of various power supply equipments under different load rates and external factors. Second, an optimal scheduling model based on the objective function of the minimum system operating cost and the maximum energy efficiency is built in consideration of carbon emission cost. Then, the author adopts Yalmip + Gurobi toolbox to solve the established optimal scheduling model on the MATLAB platform. According to the simulation results, the optimal scheduling model has the capacity of energy saving and emission reduction, and the integrated energy system can run in an efficient and economic way under the constraints of carbon emission cost and variable working condition characteristics.
