摘要:

随着碳交易市场的成熟,碳配额和国家核证自愿减排量成为微电网优化运行必须考虑的因素。针对优化运行中源荷不确定性所带来的挑战,提出了一种考虑碳交易体系的多阶段鲁棒优化模型。首先,对微电网的源荷不确定集和微电网碳交易体系进行描述,并据此建立了一系列确保微电网鲁棒性和非预期性的可行性约束。针对关于时间耦合的燃气机组和储能装置的约束条件,采用隐式决策规则,引入辅助变量和新的非预期约束,并对模型进行再表述,求解出燃气机组的启停策略及其与储能系统荷电状态的安全输出区间;进而建立日内实时滚动模型,确定了微电网各组成部分的实时功率输出,实现微电网的实时优化调度;最后,导入江苏省某地区实际数据进行算例分析,验证了所提模型的有效性,但在可再生能源已充分优化的前提下,单纯地改变碳配额交易价格对微电网运行影响较小。

Abstract:

With the maturity of carbon trading market, carbon emission allowances and certified emission reductions have become factors that must be considered in the microgrid operation optimization. To address the difficulties posed by source-load uncertainties during operation optimization, a multi-stage robust optimization model taking the carbon trading system into account is proposed. Initially, the uncertain sets of microgrid sources and loads and the microgrid carbon trading system are described, and a series of feasibility constraints ensuring the robustness and unpredictability of the microgrid are established accordingly. For the constraints related to the temporal coupling between gas-fired units and energy storage devices, implicit decision rules are employed to introduce auxiliary variables and new unpredictability constraints, and the model is reformulated to determine the start-stop strategy of the gas-fired units and the range of the battery's state of charge. Subsequently, an intra-day real-time rolling model is established to ascertain the real-time output of each component, achieving real-time optimized scheduling of the microgrid. Finally, actual data from a region in Jiangsu Province is used in a case study to analyze and verify the effectiveness of the proposed scheduling model. However, it is noted that under the premise of fully optimizing renewable energy sources, simply changing the price of carbon allowances has a weak impact on the operation of the microgrid.
