新能源并网对电能质量的影响

The Influence of New Energy Grid-connection on Power Quality

现如今,全球经济快速发展,国家对于能源的需求越来越大。随着化石能源的逐渐减少和人们环保意识的提高,我国开始关注新能源的发展。现在广泛使用的新能源有风能、太阳能、地热能,但新能源发电容易受环境影响,存在不稳定和易间断等缺陷,而大规模并网后会对电网产生一些不利影响。因此,讨论了光伏发电和风力发电的局限以及并网后可能带来的问题。

Nowadays,with the rapid development of the global economy,the country,s demand for energy is increasing.With the gradual decrease of fossil energy and the improvement of people's awareness of environmental protection,China begins to pay attention to the development of new energy.The new energy sources widely used now include wind energy,solar energy and geothermal energy.However,the new energy generation is easily affected by the environment and has some disadvantages such as instability and discontinuity.After large-scale grid connection,it will have some adverse effects on the power grid.This paper discusses the limitation of photovoltaic power generation and wind power generation and the possible problems after grid connection.
