摘要
随着新能源大规模开发,新能源消纳问题逐渐突出。在保证太阳能及风电可靠并网发电、电网能够维持安全稳定运行的前提下,不同的网架强弱程度、不同的电源构成以及不同的负荷水平,电网消纳新能源发电的能力也将有所不同。为了综合协调电网电源资源,合理安排新能源的发展规模和建设时序,保障新能源发电的科学发展和有效利用,本文基于电网光伏风电消纳能力,并根据风电发电特性、光伏发电特性及风光互补特性,提出一种探索电网新能源消纳能力最大的方法,为后续新能源并网提出指导性意见,避免大量的弃风弃光现象发生。
With the large-scale development of new energy,the issue of new energy consumption has gradually emerged.Under the premise of guaranteeing reliable integration of solar and wind power,and maintaining stable and safe operation of the power grid,renewable energy acceptability of the grid may differs from grid strengths,power structures,or load levels.In this paper,calculations of discard rate and acceptability of renewable power generation in Power Grid,and multiple renewable power integration schemes consider of the priority or the optimum ratio of solar and wind power based on the power generation and complementarity characteristics are given in order to coordinate the power and grid development,ensure the reasonable development scale and effective consumption of new energy power generation in Qinghai Province and proposed constructive advice for the follow-up new energy integration to reduce renewable power discard.
