基于电压监测的分布式电采暖实时优化控制策略

A Voltage Monitoring-Based Realtime Optimized Control Strategy for Distributed Electric Heating

  • 摘要: 近年来,电采暖作为一种清洁取暖设备逐渐在居民生活中占据重要地位,但大量电采暖接入对电网的安全运行造成影响。为缓解这个矛盾,针对分布式电采暖运行方式,构建了电采暖设备集群和电采暖设备的等效模型,对现有温度控制策略进行了改进,提出了一种基于电压监测的分布式电采暖实时优化控制策略。仿真结果表明该策略可以明显降低集群负荷的峰值和峰谷差,达到削峰填谷、平稳负荷曲线的目的,避免冬季取暖高峰期的负荷过载,保证了用户的取暖需求,降低了电采暖设备无序启动导致负荷过载对用户取暖带来的影响。

     

    Abstract: In recent years, as a clean heating device the electric heater gradually occupies an important place in the lives of residents. However, grid-connection of lots of electric heaters affects the secure operation of power grid. To mitigate such a contradiction, in allusion to the operation mode of distributed electric heating an equivalent model of electric heating device aggregation was constructed, by which the existing temperature controlling strategy was improved, and a voltage monitoring-based realtime optimized control strategy for distributed electric heating was proposed. Simulation results show that using the proposed strategy the peak value and valley-to-peak difference of the load aggregation can be reduced obviously to achieve the purpose of peak-load shifting and smoothing the load curve to avoid the overload during the winter heating peak, thus the heating demand of the inhabitant is ensured and the affection on the heating of the inhabitant because of the overload due to unordered starting of electric heating devices can be alleviated.
