摘要

一个高效、可靠的能源系统是满足不断增长的能源需求、解决环境问题和适应技术进步的必要条件。本研究的目的是在考虑发电机组、输电网和潮流约束等因素的情况下，开发能源系统集成维护调度（IMS）的最佳策略。提出的维护策略包含一个基于场景的模型，以考虑可再生能源发电的不确定性，并使用来自台湾的现实数据集进行验证。该数据集包括来自海上风电场的风速记录和带有光伏组件规格的太阳辐射记录。此外，还集成了能量存储（ES），以减轻高峰负荷期间或维护中断期间潜在的能量不足。主要目标是在遵守安全和可靠性法规的同时，最大限度地降低总运营和维护成本以及不供应能源（ENS）。针对IMS问题，建立了一个混合非线性整数规划模型。BARON求解器用于求解小规模问题，而基于遗传算法的数学求解器用于求解大规模问题。结果表明，该算法在减少计算时间的同时提高了求解效率。此外，集成ES系统可以降低ENS，并对系统成本产生积极影响。

Integrated maintenance scheduling for generators and transmission lines considering renewable energy sources and energy storages

An efficient and reliable energy system is imperative to meet the escalating energy demand, address environmental issues, and accommodate technological advancements. This study aims to develop optimal strategies for integrated maintenance scheduling (IMS) in energy systems, considering factors such as generating units, transmission networks, and power flow constraints. The proposed maintenance strategy incorporates a scenario-based model to account for the uncertainty in power generation from renewable sources, validated using a realistic dataset from Taiwan. This dataset includes wind speed records from offshore wind farms and solar radiation records with photovoltaic module specifications. Additionally, energy storage (ES) is integrated to mitigate potential energy deficits during peak load periods or maintenance outages. The primary objective is to minimize total operational and maintenance costs, and energy not supplied (ENS), while adhering to safety and reliability regulations. A mixed nonlinear integer programming model is formulated for the IMS problem. The BARON solver is used to solve small-scale problems, while a genetic algorithm-based matheuristic is developed to solve large-scale problems. The results demonstrate that the proposed algorithm improves solving efficiency while reducing computational time. Additionally, integrating the ES system reduces ENS and positively impacts system costs.
