摘要: 为促进分布式绿电的市场化消纳,提高分布式绿电机组的运行效益,对聚合分布式绿电的分布式电源运营商、储能运营商和柔性负荷聚合商利用虚拟电厂联合技术开展电能合作交易的模式进行研究。首先,在各主体之间进行电能交易的前提下建立各主体最优运行模型;然后,基于纳什议价理论建立多主体合作博弈模型,为更好求解合作博弈模型,将模型转换为合作运行总效益最大化子问题和基于非对称的收益分配子问题,用交替方向乘子法进行两个子问题的分布式求解;最后,通过算例仿真进一步验证所提模型的有效性。结果表明:参与电能合作交易能有效提高分布式绿电机组的运行效益。

Abstract: In order to promote the market-oriented consumption of distributed green power and improve the operation efficiency of distributed green power units, this paper studies the cooperative trading mode of distributed power generation operators, energy storage operators and flexible load aggregators that aggregate distributed green power by using virtual power plant joint technology. Firstly, the optimal operation model of each subject is established under the premise of energy transaction between each subject, and then the multi-agent cooperative game model is established based on Nash bargaining theory. In order to better solve the cooperative game model, the model is transformed into a sub-problem of maximizing the total benefit of cooperative operation and a sub-problem of asymmetric income distribution. The alternating direction multiplier method is used to solve the two sub-problems in a distributed manner. Finally, the effectiveness of the proposed model is further verified by simulation. The conclusion shows that participating in power cooperative trading can effectively improve the operating efficiency of distributed green power units.
