Evaluation Method for Investment Revenue of Distributed Synchronous Condensers in Renewable Energy Station Considering Marginal Contribution
摘要
Abstract
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.关键词
