基于信息互动的分布式可再生能源多代理交易竞价模型

Multi-Agent Transaction Bidding Model for Distributed Renewable Energy Based on Information Interaction

如何以市场化手段灵活解决配电网分布式能源的消纳,激励多方自主参与,已成为主动配电网商业模式研究的重要方向,适应多方分散决策的交易竞价模型是其中的关键。利用多代理建模技术构建了分布式可再生能源交易市场信息流和能量流的互动框架,设计了各参与主体交易信息的市场交互机制。各代理为提升市场竞争力,将市场信息分为电价信息、状态信息、交易信息、时间信息4类分析处理。利用信息修正模型对已生成的常规报价进行优化,依据交易结果调整各类信息影响因子,构建了源-储-荷的信息修正竞价模型,实现了竞价策略优化。算例中从参与主体、交易对象策略、市场模式3个维度对信息修正竞价模型的经济性和通用性进行了验证。

It is an important research topic to accommodate distributed energy of distribution network flexibly by means of market with multi-party transaction bidding model. Interaction of information flow and energy flow in distributed renewable energy trading market is constructed with multi-agent modeling technology. The market interaction mechanism of each piece of participant transaction information is designed. In order to enhance market competitiveness, each agent divides the market information into four types. Based on regular strategy, information correction and adjustment of affecting factors, a revised information bidding model for generation-storage-load is built. In a case study, economy and generality of the revised information bidding model is validated from three aspects, i.e. participants, transaction strategy and market mode.
