摘要： 为提高风-光-柴-储独立运行微电网的经济效益,提出一种基于储能蓄电池和柴油发电机两种主控电源动态交替运行的独立微电网经济优化运行策略.首先,基于可再生能源出力预测、负荷需求预测等基础数据,选择合理的运行模式,建立了一种包含燃料消耗成本、系统运行与维护成本等因素的最小化系统综合运行成本目标.其次,构建结合功率平衡约束、分布式发电单元运行约束等条件下的独立微电网经济运行优化模型,并提出一种基于秃鹰搜索算法(BES)的模型求解方案.最后,通过算例分析验证了所提出的优化运行策略可有效提高微电网系统的经济效益.

Abstract: To improve the economic benefits of islanded microgrid with wind turbine, photovoltaic, diesel, and energy storage, an economic optimal operation strategy based on the dynamic alternate operation of two master power supplies, namely, the energy storage battery and the diesel generator, was proposed. First, based on the basic data such as renewable energy output forecast and load demand forecast, a reasonable operating mode is selected. A goal of minimizing the comprehensive operation cost of the system is established, incorporating factors such as fuel consumption cost, system operation and maintenance cost, and so on. Second, an economic operation optimization model for islanded microgrid is constructed, considering power balance constraints, and the distributed generation unit operation constraints. A model solution scheme based on the bald eagle search (BES) algorithm is proposed. Finally, the effectiveness of the optimal operation strategy proposed in this paper is verified by a case study, which can improve the economic benefits of the microgrid systems to a certain extent.

Key words: microgrid, operation strategy, economic optimization, bald eagle search algorithm
