【 摘 要 】

Along with renewable resource dominating the evolutional trend of the further electrical structure, the uncertainty characteristics of renewable energy have made a profound influence on electrical dispatch, operation, and planning in modern renewable energy resource. As a result, the issue of quantitative capacity evaluating of accommodating renewable energy has drawn widespread concern across the home and aboard. In this paper, we fully consider the impact of both of the adjustable characteristic of nuclear plants and the external transmission power constraints caused by multi-area interconnection on the operation mode of power system with proportion of renewable energy, on this basis, a novel modified model based on unit commitment (UC) to evaluated the capacity of accommodating renewable energy of power system is proposed. Furthermore, an actual example is used to demonstrate the feasibility of the proposed method.
