近年来,分布式调相机(DSC)在大规模新能源外送工程中得到了推广应用,显著提升了新能源发电效率与系统安全稳定水平。然而,在当前市场环境下,DSC工程投资收益差异显著,在一定程度上制约了DSC的应用。针对上述问题,提出了计及边际贡献的新能源场站DSC投资收益评估方法。首先,从提升新能源发电量、提供辅助服务等方面,厘清了当前市场环境下DSC的投资回收渠道与获益方式。其次,通过量化评估DSC对近区新能源发电能力提升的边际贡献,基于Shapley值法对DSC增发电量收益进行分摊。然后,基于全寿命周期成本对不同主体投资DSC的投资运营成本和运营收益进行评估。最后,构建了大规模新能源直流外送试验系统,验证了所提投资收益评估方法的有效性,并提出了不同主体投资DSC的成本疏导建议。
In recent years
the distributed synchronous condenser (DSC) has been widely applied in large-scale renewable energy transmission system projects
significantly improving the generation efficiency of renewable energy and the security and stability of power systems. However
in the current market environment
the investment income of DSC projects varies significantly
which restricts the application of DSCs to some extent. To address the above issues
the evaluation method for investment revenue of DSCs in renewable energy stations considering marginal contribution is proposed. Firstly
the investment recovery channels and benefit mechanisms of DSCs in the current market environment are clarified from the aspects of increasing the renewable energy generation and providing auxiliary services. Secondly
by quantitatively evaluating the marginal contribution of DSCs to the renewable energy power generation capability enhancement in the near region
the additional power generation revenue is allocated based on Shapley value method. Furthermore
based on the lifecycle cost
the investment and operation cost as well as the operation revenue of different entities investing in DSC are evaluated. Finally
a large-scale renewable energy DC transmission experimental system is constructed to validate the effectiveness of the proposed evaluation method for investment revenue
and the cost-sparing suggestions are proposed for different entities investing in DSC.
