摘要
为促进综合能源系统多能协同互补互济,提高能效,以电热气互联能源系统为研究对象,提出了一种多目标协同优化的综合需求响应模型及运行策略求解算法。首先,设计了含综合需求响应的电热气互联能源系统架构,采用能量耦合矩阵对互联系统中多能转化关系进行描述,在分时能源价格机制下,构建了混合时间/空间尺度的多能协同综合需求响应数学模型。然后,以最小化的系统用能成本、环境成本和弃风弃光功率为目标,构建了环保经济优化调度模型,采用结合协同进化思想和非支配排序遗传算法的改进优化算法(Co-NSGA-Ⅱ)对模型进行求解。仿真结果表明,所提出的模型及优化运行策略能够有效提高多能系统间能量协调能力和综合需求响应能力。
In order to promote the multi-energy coordination and mutual assistance of the integrated energy system(IES) and improve energy efficiency,taking the electricity-heat-gas(EHG)-IES as the research object,a multi-objective collaborative optimization integrated demand response(IDR) model and operation strategy solving algorithm are proposed.Firstly,EHG-IES architecture with IDR is designed,and the energy coupling matrix is used to describe the multi-energy conversion relationship in interconnected system.Under the time-sharing energy pri-e mechanism,a multienergy coordinated IDR mathematical model with mixed time or space is constructed.Then,with the goal to minimize system energy cost,environmental cost,abandoning wind and optical power,an optimal dispatch model of environmental economy is constructed.The Co-NSGA-Ⅱ is used to solve this model.The simulation results show that the proposed model and optimal operation strategy can effectively promote the energy coordination ability and comprehensive demand response ability among multi-energy systems.
