独立微网电能市场区间报价报量交互式交易优化

Optimization of interactive trading of interval quotation and volume in independent micro⁃grid electricity market

针对大规模分布式参与者如何在有限交易水平下,自由灵活参与微网电能市场交易的问题,提出建立上、下层分布式交易的微网市场优化模型.其中,上层为参与者效能最大化,下层为微网社会经济效益最大化,并采用交替方向乘子法分层交互迭代求解.实例分析结果表明,所提出的模型可充分协调优化参与者效能和市场社会经济效益,提高微网可再生能源消纳、参与者效能和社会福利.

To address the problem of how large⁃scale distributed participants can freely and flexibly participate in microgrid electricity market transactions under limited transaction levels,this paper proposes to establish a microgrid market optimization model with upper and lower levels of distributed transactions,in which the upper level is to maximize participant effectiveness and the lower level is to maximize microgrid socio⁃economic benefits and solves it using the alternating direction multiplier method with hierarchical interaction iterations.The results of the empirical analysis show that the proposed model can fully coordinate the optimization of participant effectiveness and market socio⁃eco⁃nomic benefits;and it can improve the microgrid renewable energy consumption,participant effective⁃ness and social welfare.
