摘要
为保证接入可再生能源的微电网系统能够实现稳定运行,针对独立运行的风/光/蓄互补微电网系统进行分析,探讨该系统中能量的动态优化问题,提出了一种保证蓄电池容量恒定在其最大荷电量状态以保证自然条件不佳时负载不间断供电的优化策略,以最大化利用风能和太阳能为原则,以整个系统的运行发电成本最低为目标建立模型。仿真分析表明,该方法能够实时地根据当时的自然资源条件和负荷变化规律,选择最优的动态机组组合,以实现系统的经济运行。
To ensure the stand-alone microgrid with renewable energy to achieve stable operation, the dynamic optimization problem of the energy in microgrid with wind/PV/battery energy resources is explored, and the optimization strategy is proposed, for guaranteeing the capacity of battery with the maximum power state to meet uninterruptible power supply of the load in the poor condition, maximizing the utilization of wind and solar energy and minimizing the operating cost. The simula- tion results showed that the method can select the optimal dynamic unit commitment in the real time, according to the prevailing conditions of the natural resources and the load change then to achieve the economic operation of the system.
