P2P模式下产消者交易模型建立与仿真验证

Establishment and Simulation of Prosumers Transaction Model in P2P Mode

随着新电改环境下售电侧放开,越来越多的产消者资源愿意参与到电力市场中以减少自身的用电开支,如何在P2P(peer-to-peer)交易模式下制定产消者购售电模型成为一个亟待解决的问题。首先,以含光伏(photovoltaic,PV),微型燃气轮机和固定负荷资源组成的多个产消者集群为研究对象,建立了产消者资源约束模型。其次,采用拉格朗日对偶分解原理和次梯度法以产消者运行成本最小为目标制定了基于P2P市场交易模式的产消者购售电计划。在保证用户的信息安全的同时实现了产消者之间的P2P电能共享。最后通过算例验证了所提策略的合理性和有效性。

With the liberalization of the electricity selling side in the new electricity reform environment,more and more prosumers are willing to participate in the electricity market to reduce their own electricity consumption expenditure.How to develop the electricity purchasing and selling model for prosumers under the P2P trading mode has become an urgent problem.Firstly,the paper proposes the prosumer resource models for photovoltaic(PV),micro-gas turbine and fixed load resource clusters,respectively.Secondly,lagrange duality decomposition principle and sub-gradient method are adopted to develop the electricity purchase and sale plan for prosumers based on the P2P market transaction mode with the objective of minimizing the operating cost of prosumers,by which the P2P power sharing between prosumers can be realized.Finally,an example is given to verify the rationality and effectiveness of the proposed strategy.
