摘要:

目的 户用微电网是新型电力系统的重要组成部分,其优化运行对提高可再生能源利用率、降低系统的运行成本非常重要。但是,光伏等分布式电源的出力及负荷的强不确定性给户用微电网的优化运行带来很大挑战,为此,提出了一种基于信息间隙决策理论(information gap decision theory,IGDT)的鲁棒优化运行模型。 方法 首先,充分考虑分时电价的影响,建立以用户成本最低为目标的并网型户用微电网优化运行模型;然后,在该模型基础上,综合考虑光伏、负荷和电动汽车充电等不确定性因素对户用微电网优化运行的影响,构建基于IGDT的鲁棒优化运行模型;最后,采用分层序列法结合熵权法对模型进行求解。 结果 通过蒙特卡洛模拟,验证了IGDT鲁棒模型处理光伏和负荷等不确定性时的有效性和可靠性。 结论 该模型为户用微电网的优化运行提供了一种可行的解决方案,对提高户用微电网的运行经济性和分布式可再生能源的就地消纳率具有重要意义。

Abstract:

Objectives Residential microgrids are an important part of the new-type power system, and their optimal operation is crucial for improving the utilization efficiency of renewable energy and reducing system operating costs. However, the strong uncertainties in the output of distributed power sources such as photovoltaics, as well as in loads, pose significant challenges to the optimal operation of residential microgrids. Therefore, a robust optimal operation model based on information gap decision theory (IGDT) is proposed. Methods Firstly, by fully considering the influence of time-of-use electricity prices, an optimal operation model for grid-connected residential microgrids is established with the objective of minimizing user costs. Then, on the basis of this model, a robust optimal operation model based on IGDT is established by comprehensively considering the influence of uncertain factors such as photovoltaic output, load, and electric vehicle charging on the optimal operation of residential microgrids. Finally, a hierarchical sequencing method combined with the entropy weight method is used to solve the model. Results Through Monte Carlo simulations, the effectiveness and reliability of the IGDT-based robust model in addressing uncertainties such as photovoltaic output and load are validated. Conclusions This model provides a feasible solution for the optimal operation of residential microgrids. It is of great significance for improving their economic performance and the on-site consumption rate of distributed renewable energy.
