基于光伏发电的配电网电源结构优化模式研究

Study on Optimization of Power Distribution Network Structure Based on Photovoltaic Power Generntion

从减少系统投资和节约能源的角度出发,提出一套不带储能环节的低成本光伏发电系统设计方案。该方案将光伏阵列和配电网同时作为负荷的两路电源,在太阳辐射量充足时负荷由光伏阵列提供电能;当太阳辐射变弱时,电网电能平滑切入补充,达到太阳能发电即发即用的目的,有效实现太阳能的就地消纳利用。

This article put forward a set of low-cost photovoltaic system without energy storage from the perspective of reducing investment and save energy. In this scheme,the photovoltaic array and power grid are as two power supply of a load at the same time,the photovoltaic array provides electricity when solar energy is sufficient.When solar radiation is weak,the grid electricity smoothly cuts added to achieve the purpose of using solar energy in real time and effectively.
