| 摘要: |
| 目前，电采暖设备作为新能源消纳的有效途径存在源荷匹配性低、档位优化不足的问题。针对上述问题，提出一种基于电采暖设备集群控制架构的多功率级控制策略。首先，考虑电采暖用户舒适性、经济性及公平性目标，通过改进多目标粒子群算法(IMOPSO)确定最优基准档位。然后，建立综合加权指标与档位差值对应关系，确定电采暖多功率级最优档位差值。最后，以设备状态与负荷转移量为约束，实现电采暖设备多功率级控制。算例仿真结果表明，所提策略相比于传统控制方法可进一步实现新能源精准消纳，在提高负荷柔性的基础上提升用户采暖舒适度，为电采暖集群新能源消纳控制策略提供新的可行性方法。 |

| Abstract: |
| At present, as a potential effective way of absorbing new energy, electric heating equipment has the problems of low source-load matching and insufficient tap position optimization. Thus a multi-power level control strategy based on a cluster control architecture of electric heating equipment is proposed. First, considering the objectives of user comfort, economy and fairness of electric heating, the optimal benchmark gear is determined by an improved multi-objective particle swarm optimization (IMOPSO) algorithm. Then, a corresponding relationship between comprehensive weighted index and gear difference is established to determine the optimal multi-power grade gear difference. Finally, multi-power level control of electric heating equipment is realized by constraining the equipment state and load transfer amount. The simulation results show that compared with the traditional control method, the proposed strategy can further realize the accurate absorption of new energy, improve user heating comfort level on the basis of improving load flexibility, and provide a new feasible method for the new energy absorption control strategy.
