一种应用于智能电网的建筑电力负荷互动管理策略

Interactive building power load management strategy for smart grid

电力供需失衡是电网运营面临的一个严峻问题,电力的供给侧和需求侧通过有效管控均能舒缓和解决该问题。采用电力动态定价和建筑热质蓄能量化的思路,提出一种智能电网与建筑进行信息交互的电力负荷管理框架及策略,为智能电网实现"移峰填谷"及提升负荷系数提供新的参考模式。应用简化的建筑热物理模型和若干建筑室内温度控制策略快速评估建筑电力需求响应能力。仿真结果验证了所提方法的有效性。

The power imbalance between supply and demand sides is a critical issue for grid operation,which can be eased and solved by the effective management and control of supply and demand sides. Based on the dynamic pricing of electric power and quantification of energy storage in building thermal mass,a power load management framework and strategy for information interaction between smart grid and buildings is proposed,which provides a novel reference mode for smart grid to achieve peak load shifting and increase load coefficient. The simplified building thermal physical models and several indoor temperature control strategies are used to fast estimate the demand response capability of building power. Simulative results verify the effectiveness of the proposed method.
