摘　　要：分布式可再生能源在主动配电网中的渗透率逐年增加,主动配电网的分布式特性日益凸显;传统的集中能量调度难以解决分布式能源出力随机性的协调以及大量分布式数据的通讯压力。文章以分层多代理模型为控制结构,提出一种基于价格引导的分布式可再生能源协调策略。详细介绍了各Agent的协调模型,区域目标、价格的协调响应策略及区域安全约束条件,利用Agent的分布自治、全局协作实现主动配电网的能量平衡同时促进分布式可再生能源的消纳;协调策略关注电价调整对储能、柔性负荷响应能力的影响,以提高分布式可再生能源消纳。最后,通过指标量化分析策略的综合性能,对比传统时序模拟方法的评估结果,验证了所提方法的合理性、有效性。The increasing penetration of distributed renewable energy（DRE） has posed challenges to the centralized characteristics of active distribution network. The conventional centralized energy scheduling can hardly coordinate the probabilistic generation of highly dispersed DRE. A large volume of distributed data communication, in addition, causes the investment cost burden. This paper proposed a price coordination strategy of DRE based on hierarchical multi-agent system（MAS）. Meanwhile the agent models, regional targets, constraints and power coordination strategies based on price were described in details. Utilizing agent characteristics for power balance of active distribution network（AND） and others for distributed generation（DG）optimization control strategies combined with both system global target and DG individual. The coordination strategy focused on the influence of electricity price adjustment for energy optimization scheduling in order to improve the distributed renewable energy. Finally, use evaluation index analysis comprehensive performance of strategy, the feasibility of the strategy is verified which compared to traditional method.
