新能源微电网负载自动匹配系统

Load auto matching system for micro-grid consisted of new energy

分布式新能源发电的发展,一定程度上扩大了能源种类,缓解了能源紧张。但其发电并网消纳问题目前依然没有有效解决。受天气影响,新能源发电系统的输出波动将影响电网的稳定运行。提出一种负载自动匹配方案,通过跟踪新能源发电及负载运行情况,采用投退加热器的方式进行负载调节,以期解决发电并网消纳问题,并帮助海岛或偏远地区可以稳定地使用新能源微电网。

With the development of distributed generation by new energy, it extended the type of using energy and eased the energy shortage. But the absorption problem of grid-connecting of new energy is still not solved effectively. Affected by weather, the fluctuation of the output of the new energy will be harmful to the stability of grid. This paper provides a method of load auto matching system which can adjust loads through opening or closing heaters, following the running condition of new energy system and loads. It is aimed to solve the absorption problem and increase the stability for the micro-grid consisted of new energy in island or remote area.
