Abstract

This paper addresses the energy management control problem of solar power generation system by using the data-driven method. The battery-supercapacitor hybrid energy storage system is considered to smooth the power fluctuation. A new model-free control method is utilized in the stand-alone photovoltaic DC-microgrid to provide the power to meet the demand load, while guaranteeing the DC bus voltage is stable. Furthermore, the proposed data-based power management control strategy only needs I/O data. Numerical simulations with real data verify the effectiveness of the proposed method.

摘要

本文采用数据驱动方法解决太阳能发电系统的能量管理控制问题。考虑使用电池-超级电容器混合储能系统来平滑功率波动。在独立光伏直流微电网中采用一种新的无模型控制方法，以提供电力来满足需求负载，同时保证直流母线电压稳定。此外，所提出的基于数据的功率管理控制策略仅需要输入/输出数据。利用实际数据进行的数值模拟验证了所提方法的有效性。
