【摘要】：近年来我国风电发展迅速,已成为第三大电源。由于风力发电存在波动性和反调峰等特性,其并网优先调度后,将给传统发电机组带来影响,如运行方式的改变所带来的运行成本和机组寿命的变化等。运用外部性理论并采用随机生产模拟模型,基于IEEE-RTS79系统分析了风电渗透率达到23.5%的大规模风电并网优先调度情景下,风电优先调度给发电企业带来的外部性成本。算例分析表明,风电优先调度对承担基荷的机组带来的负外部性成本较小,但会对其他机组带来显著的负外部性,并且与机组发电的边际成本存在正相关关系。最后的量化结果可为未来的补偿机制设计提供相应的依据,以促进风电在我国市场环境下的健康持续发展。
[Abstract]:Wind power in China has developed rapidly in recent years and has become the third largest power source. Due to the characteristics of wind power generation such as volatility and anti-peak-shaving, it will have an impact on the traditional generator set after priority dispatching. For example, the change of operation cost and unit life caused by the change of operation mode, using externality theory and stochastic production simulation model, based on IEEE-RTS79 system, analyzes the priority dispatching scenario of large-scale wind power with 23.5% wind power permeability. The example shows that the negative externality cost of wind power priority dispatching to the units bearing the basic load is small, but it will bring significant negative externalities to other units. Finally, the quantitative results can provide the corresponding basis for the future compensation mechanism design, in order to promote the healthy and sustainable development of wind power in the market environment of our country.
