高密度多接入点分布式光伏接入系统方案分析

Solution Analysis Of High Density Multi Access Point Distributed Photovoltaic Access System

随着光伏发电在电力系统中所占比重的逐年增大,其接入系统方案的优化选择成为电网在接纳光伏发电之前首先需要解决的问题之一。因此,本文以拟建的某分布式光伏电站为例,对高密度多接入点分布式光伏的接入系统方案进行了研究和分析,重点从系统有功损耗和经济效益等多方面进行了综合比选,在保证分布式光伏系统正常发电的前提下,提出了有利于自发自用、就地消纳、有效降低网损及经济效益的推荐方案。

While the proportion of photovoltaic power generation in the electrical power system is increasing year by year, its access system optimizing choice has become one of need-to-be- solved problems before accepting photovoltaic power generation. In this paper, based on a distributed photovoltaic power station case, it discussed and analyzed high density multi access points distributed PV access system solutions. It mainly focused on comprehensive comparison from several aspects, such as system active power loss and economic benefit. Under the premise of ensuring the normal distributed photovoltaic system power generation operation, it put forward recommended solutions for spontaneous generation for personal use, elimination on the spot, effectively reducing network loss and obtaining economic benefit.
