综合能源系统是能源互联网的物理载体,可以提升能源利用效率,因此其优化调度受到了各国学者的广泛关注。对综合需求响应和多能储能装置的运行模型进行建模;以综合能源系统总运行成本最小为目标函数,构建考虑综合需求响应和多能储能装置的综合能源系统优化调度模型;运用条件风险价值方法处理可再生能源出力的不确定性。以某电-热-冷综合能源系统为例进行算例分析,结果表明所提模型可以降低综合能源系统运行成本,有效衡量可再生能源出力不确定性带来的运行风险。

As a physical carrier of energy Internet,integrated energy system can improve energy utilization efficiency.Therefore,its optimal dispatching has attracted extensive attention of scholars all over the world.Firstly,the comprehensive demand response and the operation model of multi-energy storage device are modeled;Then,the minimum total operation cost of the integrated energy system is taken as the objective function to construct the optimal dispatching model of the integrated energy system considering the comprehensive demand response and multi-energy storage devices;Then,the CVaR(conditional value at risk)is used to deal with the output uncertainty of renewable energy;Finally,an example of an electric-heat-cold integrated energy system is analyzed.The results show that the model proposed in this paper can reduce the operation cost of the integrated energy system and measure the operational risk caused by output uncertainty of renewable energy.
