园区综合能源系统优化调度研究与实践

Research and practice on optimal scheduling of park-level integrated energy system

园区综合能源系统在实现能源梯级利用、优化能源结构、促进节能减排等方面起到了积极作用。结合综合能源系统实际管控的业务需求,在考虑智慧园区多能平衡、多样化用户需求的基础上,建立了综合能源系统超结构模型,并对其中的关键能源设备进行建模分析。以经济性、环保性和稳定性为优化目标,建立多能系统多时间尺度优化调度模型,制定能源运行的优化调度策略。将该方法运用于实际工业园区的综合能源优化调度中,可以有效地提升能源的综合利用效率。

The park-level integrated energy system plays a positive role in realizing the cascade energy utilization,optimizing energy mix,promoting energy conservation and emission reduction.In line with the actual business demand of integrated energy system management and control,a superstructure model of integrated energy system was established considering multi-energy balance and diversified demand of users in smart park,and key energy equipment therein were modeled and analyzed.A multi-time-scale optimal scheduling model of multi-energy system was built,and an optimal scheduling strategy for energy system operation was mapped out,for the purpose of economy,environmental protection and stability.Finally,the model was applied to optimal scheduling of the integrated energy system in an industrial park,improving the comprehensive energy utilization.
