智能楼宇用电负荷优化调度

Optimal Dispatch of Electricity Load for Smart Buildings

现阶段中国建筑能源消耗较大,浪费现象频现,同时,光伏等新能源分布式发电在用户侧大力推广,如何在优先消纳分布式发电的情况下管理大型楼宇用电,节约电量,降低电费,成为了近年智能楼宇建设的关键问题。对智能楼宇用电管理系统的分层架构体系进行了简单介绍,并通过对用户负荷分类,以用电经济性、舒适性和电网稳定性为目标提出了负荷优化调度模型,之后采用遗传算法求解模型最优解,实现对可转移负荷和可中断负荷的调度,达到楼宇节能减排的目的。

At this stage,China's building energy consumption is relatively large,and waste often occurs.At the same time,new energy distributed power generation such as photovoltaics is vigorously promoted on the user side.How to manage the power consumption of large buildings under the condition of prioritizing the consumption of distributed power generation to save power and reduce electricity fees have become a key issue in the construction of smart buildings in recent years.This paper carried out a brief introduction to the hierarchical architecture system of the intelligent building power management system,and proposed a load optimization dispatch model with the goals of economy and comfort in using electricity and grid stability through the classification of user loads,and then solved the optimal solution of the model by genetic algorithm to realize the dispatch of the transferable load and the interruptible load,and achieve the goal of building energy saving and emission reduction.
