中文摘要： 在新能源发电大规模发展的背景下，合理调控接入配电网的分布式可控资源对于电力系统的安全与经济运行具有重要意义。调控不同分布式资源需要的量测、通信和控制系统类似，将多种分布式资源聚合调控更能发挥其规模效应和互补作用。项目以四类分布式可控资源为对象，即灵活负荷、电动汽车、分布式储能设备和分布式电源，首先研究各类分布式可控资源的特性和数学模型。其次，在研究每类分布式资源分层调控策略的基础上，提出调控多种分布式资源的系统构架，深入研究多种分布式资源聚合的多时间尺度、分层优化调控策略。调控的主要目标包括削峰填谷、最优潮流、参与调频和降低电网全年最高负荷。最后，在综合成本-效益分析的基础上研究对分布式可控资源的价格激励和市场机制。项目的主要特色在于全面考虑接入配电网的可控资源，提出以分层优化和博弈理论为工具，采用集中与分散控制相结合的混合调控方法，并通过有效的激励机制设计，从而实现整个社会效益最优。

英文摘要： Under the background of integration of large-scale renewable energy generation, it is significant that the distributed controllable resources (DCRs) connecting to distribution networks can be dispatched optimally. The infrastructures including metering, communication and control that should built to dispatch different DCRs are similar, so the scale and complementary effects will be produced when multi-type DCRs are well aggregated and coordinated. The DCRs considered in this project include four types, i.e. flexible loads, electric vehicles, distributed energy storage devices and distributed generators. Firstly, the research work of this project focuses on analyzing the characteristics and building mathematical models of DCRs. Then, the system architecture for dispatching different DCRs will be proposed based on the study of hierarchical control strategies of each type of DCR. Furthermore, the multi time-scale and hierarchical control schemes will be intensively studied for collectively optimal dispatch of different DCRs. The dispatch objectives include peak shaving and trough filling, optimal power flow, frequency control and annual peak load reduction. Finally, research on price-incentive and market mechanism design will be carried out for DCRs participating power system optimal operation based on comprehensive cost-benefit analyses. The main contributions of this project lie in: taking different DCRs into full consideration, proposing the combined central and distributed control method to dispatch DCRs based on hierarchical optimization and gaming theories, and achieving the social benefit maximization through effective incentive mechanism design.
