中文摘要： 促进可再生能源利用，推动用能低碳化是发展智能电网的重要目标。在智能配电网环境下，将主动负荷响应资源与分布式可再生能源发电有机集成，不仅可提高清洁能源利用率，降低间歇性发电并网的不利影响，还可为市场各方带来显著效益。然而，由于可再生能源与负荷响应在运行上具有高度不确定性，二者集成的合理性不仅决定着系统的经济与环境效益，还会对其安全运行产生重要影响。本课题以智能配电网下源荷稳健交互为切入点，首先研究负荷功率及能量的聚合可调控性及其时空演化规律。在此基础上，研究智能配电网下源、荷资源的典型集成模式及综合效益评价指标体系。基于上述模式，引入鲁棒优化理论，重点研究智能配电网下电动汽车充换电站与可再生能源发电的协同规划方法以及分散负荷参与平抑可再生能源波动的资源整合方法。本项目的研究将有利于推动配电系统规划理论的创新，为大规模可再生能源就地消纳提供新的理论依据和技术支持。

英文摘要： The great significance for developing the smart grid is to promote the use of renewable energy and low-carbon energy. The rational integration in a smart distribution grid of active load response resources and distributed renewable energy generation can improve the utilization ratio of clean energy and reduce the adverse effect on grid connection due to intermittent power generation, while bringing economic benefits to the market. However, there is high degree of uncertainty in both renewable energy generation and load response. Therefore the rationality of the integration not only determines the system’s economic and environmental benefits, but also has an impact on its safe operation.This research takes the robust interaction between source and load in a smart distribution network as an entry point and studies the aggregation adjustability of load and energy as well as its space-time pattern, then building an equivalent model of load cluster response. On this basis, typical integration modes of source and load resources under smart distribution networks are studied and an evaluation index system of comprehensive benefits will be built. Based on the above-mentioned modes, a robust optimization method was introduced, as two issues should be focused: integrated planning methods of stations for electric vehicles and renewable energy generation in smart distribution grids; capacity consolidation methods for scattered load participated stabilization of renewable energy fluctuation. This research will be conducive in promoting the innovation of distribution system planning theory and will provide a new theoretical basis and technical support for the local consumption of large-scale renewable energy.
