摘要/Abstract

摘要： 充分利用电热器（electric heater，EH）和蓄热器（heat storage，HS）的调节能力是减少弃风的有效措施。针对目前EH和HS多为集中式容量优化，容易突破电网运行约束的问题，提出考虑容量分布的电热器和蓄热器分布式优化配置方法。以8节点简化的实际电网为例，基于直流潮流模型，考虑EH、HS等设备的容量、运行约束和具体分布，建立综合能源系统数学模型；在此基础上，以经济效益最优为目标，给出EH和HS在满足一定热负荷比例时的最优分配。仿真结果表明：EH和HS处于最优分配时，会缓解系统的弃风现象，并显著提高系统经济效益。

Abstract: It is an effective measure to reduce wind power curtailment by making full use of the adjustable capacity of electric heater (EH) and heat storage (HS). However, most of the current research focuses on the concentrated capacity optimization of EH and HS, which is easy to break through the constraints of grid operation. In view of this, this paper proposed an optimal configuration method of EH and HS considering capacity distribution. Taking the symplified 8-node actual power grid as an example, a comprehensive energy system mathematical model is established based on the DC power flow model, which considers the capacity, operation constraints and specific distribution of EH ans HS. On this basis, taking the optimal economic benefits as the goal, the optimal distribution model of EH and HS is given which meets a certain heat load ratio. The simulation results show that the phenomenon of wind power curtailment of the system will be reduced, and the economic benefits of the system will be significantly improved when EH and HS are in the optimal allocation.

Key words: integrated electric-thermal system, wind power curtailment, electric heater, heat storage, optimal configuration
