Abstract

This paper develops a method for planning smart grid functions for residential loads. The proposed planning method is developed based on defining an equivalent battery storage unit (BSU) at the distribution transformer, which feeds residential loads to be operated by smart grid functions. The power ratings of the equivalent BSU are set to match the power ratings of all controllable appliances (water heaters, air conditioners, and heating units) in the residential loads to be operated by smart grid functions. Moreover, the charge and discharge durations of the equivalent BSU are set as the off-peak-demand and peak-demand times, respectively. The equivalent battery-based planning method is tested for residential loads fed by 5 different distribution transformers. These residential loads are set to be operated by smart grid functions. Test results demonstrate the ability of the proposed method to be used for planning accurate, effective, and stable actions of smart grid functions, with minor sensitivity to the levels of power demands and/or type of controlled appliances.

基于虚拟电池的住宅负荷智能电网功能规划方法

本文提出了一种住宅负荷智能电网功能规划方法。提出了一种基于在配电变压器处定义等效电池储能单元(BSU)的规划方法，该单元为住宅负荷供电，由智能电网功能运行。将等效BSU的额定功率设置为与智能电网功能运行的住宅负荷中所有可控电器(热水器、空调、采暖机组)的额定功率相匹配。将等效BSU的充电和放电时间分别设置为非峰需时间和峰需时间。对由5台不同配电变压器供电的住宅负荷进行了等效蓄电池规划方法的试验研究。这些住宅负荷将由智能电网功能控制。测试结果表明，所提出的方法能够用于规划智能电网功能的准确、有效和稳定的行动，对电力需求水平和/或受控设备类型的敏感性较小。
