摘要:

本文提出了一种动态内部预测性电力调度(DIPPS)方法,用于优化微电网的电力管理,特别是针对多样化产消者之间的外部电力交换。DIPPS利用一个具有时间变化二进制参数的动态目标函数来控制电力传输到外部电网的时间,通过高效利用储能系统来处理过剩的可再生能源。微电网电力调度问题被建模为混合整数非线性规划(MINLP-PS),并通过McCormick松弛转换为混合整数线性规划(MILP-PS)优化以降低计算复杂度。一个包含6个数据点的预测窗口在平均0.92秒内得到解决,比MINLP-PS公式所需的38.27秒提高了97.6%,表明DIPPS方法在实时应用中的数值可行性。最后,该方法通过具有不同时间变化参数的三个案例研究,使用真实世界负载数据验证了静态目标方法,展示了DIPPS在优化电力交换和高效利用分布式资源方面的能力,同时将外部电力传输转移到指定的时间段。

英文摘要:

This paper presents a Dynamic Internal Predictive Power Scheduling (DIPPS) approach for optimizing power management in microgrids, particularly focusingon external power exchanges among diverse prosumers. DIPPS utilizes a dynamic objective function with a time-varying binary parameter to control the timing of power transfers to the external grid, facilitated by efficient usage of energy storage for surplus renewable power. The microgrid power scheduling problem is modeled as a mixed-integer nonlinear programmig (MINLP-PS) and subsequently transformed into a mixed-integer linear programming (MILP-PS) optimization through McCormick's relaxation to reduce the computational complexity. A predictive window with 6 data points is solved at an average of 0.92s, a 97.6% improvement over the 38.27s required for the MINLP-PS formulation, implying the numerical feasibility of the DIPPS approach for real-time implementation. Finally, the approach is validated against a static objective using real-world load data across three case studies with different time-varying parameters, demonstrationg the ability of DIPPS to optimize power exchanges and efficiently utilize distributed resources whie shifting the eexternal power transfers to specified time durations.
