    摘要:

    针对离网型微电网需求响应中用户最低电费成本的问题,提出一种基于IGDT?Stackelberg博弈的离网型微电网需求响应经济调度优化方法。首先,基于信息间隙决策理论求解可再生能源发电功率的不确定区间;然后,根据发电侧对策略风险的接受度,计算可再生能源出力期望;最后,利用Stackelberg博弈模型管理双侧策略迭代交互,确定供给侧发电机组最优出力分配,以减少发电成本。实验结果表明,本文提出方法可显著降低需求侧日负荷峰谷比,且与现有方法相比,在规避光伏机组出力预测偏差风险的基础上使用户用电费用最低。

    Abstract:

    In view of the minimum electricity cost for users in the demand response of off-grid microgrids, an economic dispatch optimization method for the demand response of off-grid microgrids based on the IGDT-Stackelberg game is proposed. Firstly, the information gap decision theory is used to solve the uncertainty interval of renewable energy generation power. Secondly, the renewable energy output expectation is calculated based on the acceptance of strategy risk on the generation side. Finally, the Stackelberg game model is used to manage the iterative interactions of the two-side strategies to determine the optimal output allocation of the generating units on the supply side, so as to reduce the cost of generation. The experimental results show that the proposed method can significantly reduce the peak-to-valley ratio of daily loads on the demand side and minimize the electricity consumption cost for users compared with the existing methods while circumventing the risk of photovoltaic (PV) unit output prediction bias.
