摘要
为了提高煤矿微电网系统效益和能源利用率,以煤矿全年综合净效益为目标函数,综合考虑建设煤矿微电网所需成本、产生的收益及多种约束条件,建立了含煤层气发电的煤矿微电网容量优化配置模型。根据全年的风力发电机组发电功率、光伏电池发电功率和负荷数据,采用粒子群算法对容量优化配置模型进行求解,获得分布式电源和储能设备的安装容量。通过算例仿真得到最优配置方案,成本与收益分析表明,微电网与大电网功率交互过程产生了收益;同时分析了可再生能源比例和自发自用率等不同运行指标对配置结果的影响,研究结果可为煤矿微电网的设备容量规划提供参考。
In order to improve efficiency and energy utilization rate of coal mine microgrid system,optimal configuration model of coal mine microgrid capacity for power generation with coalbed methane was established taking comprehensive net benefit of coal mine as objective function,and taking cost,generated income and various constraints of coal mine microgrid into consideration.According to power generation of wind turbine generator and photovoltaic battery and load data of the whole year,particle swarm optimization algorithm is used to solve the capacity optimization configuration model,and installation capacity of distributed power and energy storage equipment are obtained.The optimal configuration scheme is obtained through example simulation,and cost and benefit analysis show that the power exchange process between microgrid and large grid generates generate revenue.At the same time,the effects of different operating indicators such as renewable energy ratio and spontaneous use rate on the configuration results were analyzed,and the research results can provide reference for equipment capacity planning of coal mine microgrid.
