| 摘 要： | 为促进电能、热能、冷能等多种形式能源资源的协调配合,实现不同能源间的互补互济和高效利用,提出一种计及电热能量交易的区域综合能源系统容量优化配置方法。将系统与电网热网的能量交互费用纳入总成本,优化目标为综合考虑系统经济性、环保性、可靠性及交互功率波动的多目标函数,基于能源集线器优化区域内各供能设备容量,结合分时电热价和典型日系统经济运行采用遗传算法求解。最后通过某园区算例验证其有效性,结果表明,所提方法能够有效降低系统成本,合理避免系统规划阶段因决策因素单一导致的局限性,从而为实际系统的规划设计提供参考依据。

| Abstract: | An optimal capacity allocation method for regional integrated energy systems with electric heating energy transactions is presented in this paper to promote and achieve coordination, complementarity and high-efficiency utilization of various forms of energy resources such as electricity, heat, cold energy. The cost of energy exchange between the system and the grid is taken into the total cost. A multi-objective function, considering the economy, environmental benefits, reliability and exchange power fluctuation, is proposed to optimize the capacity of energy supply equipment in the region based on the energy hub. The genetic algorithm is used to solve the model based on time-of-use price and the typical daily operation scenario. Finally, an example of a certain park is given to verify its effectiveness. The results show that the proposed method can effectively reduce the system cost and avoid the limitations caused by the single decision factor in the system planning stage, and provide a reference for the planning and design of the actual system. |
