在这项工作中，净计量与上网电价（FiT）支持计划的住宅光伏系统进行了比较评估。以半小时为间隔，提出了一种计算净计量支持方案参数的公式，并对典型的屋顶光伏系统户进行了研究。通过改变光伏容量来研究光伏系统规模对净计量支持方案的影响，通过改变电力零售成本率来研究电力零售成本率的影响。比较结果表明，当考虑到家庭电费时，净计量支持方案比FiT支持方案表现更好。分析表明，在一定条件下，网计量支持方案是有利的。
In this work, a comparative assessment of net metering vs. feed-in-tariff (FiT) supporting schemes for residential PV systems is carried out. A formulation for the computation of net metering supporting scheme parameters, in half hour intervals, is developed and typical household integrated with a rooftop PV system is investigated. The effect of the size of PV system with respect to the net metering supporting scheme is examined by varying the PV capacity and the effect of the electricity retail cost rate is investigated by varying the electricity retail cost rate. The comparative results indicate that net metering supporting scheme performs better than a FiT supporting scheme when the household electricity bill is taken into account. From the analysis it is clear that under certain conditions net metering supporting scheme becomes profitable.
