摘要

本文探讨了在柴油-可再生能源(RES)隔离微电网中降低燃料消耗的挑战,尤其关注柴油发电机组(DG)的运行。该研究引入了一个基于基本规则的能源管理系统,作为一个平台,以一种新颖的方法测试各种 DG 运行策略。研究探讨了两种优化策略--负载调度优化和机组承诺优化--以在不同的并网 DG 之间不公平地分配负载,并分别根据预测的需求曲线安排其启动/停止顺序。此外,还研究了提供旋转储备的电池的集成,以减轻 DG 的旋转储备约束,从而提高运行负荷,进而提高效率。在塔希提电力系统的案例研究中应用了所提出的模型,结果表明燃料消耗有所减少。与没有电池的基本 DG 运行相比,综合应用所提出的 DG 负荷调度和机组承诺优化以及集成旋转储备电池,一年内可减少 2.6% 的燃料消耗和 6 千吨的二氧化碳排放量。

A novel algorithm for optimizing genset operations to minimize fuel consumption in remote diesel-RES microgrids
This paper addresses the challenge of reducing fuel consumption in Diesel-RES (Renewable Energy Sources) isolated microgrids, particularly focusing on Diesel Genset’s (DG) operation. The study introduces a basic rule based energy management system that serves as a platform to test out various DG operational strategies with a novel approach. Two optimization strategies—load dispatch optimization and unit commitment optimization—are explored to unequally distribute loads among different grid-connected DGs and sequence their start/stop based on predictive demand profiles respectively. Additionally, the integration of a spinning reserve-providing battery is investigated to alleviate DGs from their spinning reserve constraint, resulting in higher operational loads and consequently higher efficiency. The proposed model is applied on a case study of the Tahitian power system, demonstrating reductions in fuel consumption. The combined application of the proposed DG load dispatch and unit commitment optimizations, along with the integration a spinning-reserve-providing battery, yielded a 2.6 % reduction in fuel consumption and 6kt decrease in CO2 emissions over a year compared to a basic DG operation without a battery.
