摘 要: | 随着微电网技术的不断发展,家庭型微电网逐步受到关注。考虑到家庭用电功率和用电量的限制,家庭型微电网全寿命周期的经济性分析是一个值得研究的重要问题。在此背景下,考虑到经济性与所采用的电价机制密切相关,针对采用阶梯电价和峰谷电价2种机制,提出家庭型微电网全寿命周期的经济性分析方法。首先分析这2种电价模式下的投资成本和投资收益,在此基础上建立用于家庭型微电网经济性分析的数学模型,并以广州地区一个家庭型微电网系统为例来分析全寿命周期下的经济性。计算结果表明,家庭型微电网的经济性在相当程度上受投资成本的影响;在家庭型微电网系统设备容量配置已经确定的前提下,其经济性水平与用电负荷和用电量呈正相关,且受电价机制影响。

Life-Cycle Economic Analysis of Home-Based Microgrid under Different Electricity Pricing Mechanisms |
| |
Abstract: | With the continuous development of microgrid technology, home-based microgrid systems have gradually attracted increasing attention. Considering the limited demands of electric power and electric energy of an individual residential consumer, the economic analysis of a home-based microgrid within its life cycle is then an important issue to be examined. Given this background, this paper proposes the life-cycle economic analysis of a home-based microgrid system with respect to the tiered electricity pricing and time-of-use electricity pricing mechanisms respectively, with considering that the economy is closely related to the adopted electricity pricing mechanism. First, we analyze the investment and benefit of a home-based microgrid system under these two pricing mechanisms. On this basis, we construct the mathematical model for the economic analysis on home-based micro-grid, and employ an actual home-based microgrid system in Guangzhou to demonstrate the life-cycle economy. The calculation results show that the economic benefit of a home-based microgrid system is highly dependent on the investment cost, and under the fixed equipment capacity in home-based micro-grid, it is positively related to the demands of both electric power and electric energy as well as the enforced pricing mechanism. |
