含分布式电源P2P交易的社区微网运营机制

A Framework of Operating Mechanism Based on Peer-to-Peer Transaction Among Distributed Energy Resources in Community Microgrid

随着越来越多的分布式电源通过微网接入配电网,在微网中开展基于分布式交易机制的新能源交易可以有效提高分布式主体的效益,促进新能源的投资建设。文章构造可交易能源系统在社区微网运营中的应用场景,建立适合含有分布式电源和储能的社区微网用户之间的P2P交易模型。微网用户可以在P2P市场中对需求或多余电量以按报价支付的方式交易,将交易形成智能合约,存储在分布式网络中并自动执行。最后用实际微网的仿真算例验证新能源分布式交易对社区微网中所有用户效益的促进作用。

As more and more distributed energy resources（ DER） are connected to the distribution systems through microgrid,the renewable energies trading in microgrid based on peer-to-peer（ P2P） transaction can effectively improve the benefit of customers and promote the investment of renewable energies. This paper describes the application scenarios of transactive energy（ TE） system in community microgrid,and proposes a framework of P2P transaction among the consumers and prosumers（ i.e. customers with DER） in microgrid. Customers can trade their energy production or demand in the P2P market in a way of pay-as-bid（ PAB）,create and save smart contracts in the P2P network and execute them automatically. Simulation results of a test microgrid shows that all types of customers in community microgrid can achieve cost saving through P2P transaction.
