摘要
为了更好地解决离网型微电网的"源-荷"匹配问题,减轻以往能量管理过多依赖预测信息的弊端,在对储能电池SOC状态的变化趋势研究和工程实践的基础上,针对不同运行方式和运行场景,采用了基于专家规则的控制策略,充分利用微网能量管理系统的一体化数据采集和处理,保证能量管理可以依据储能SOC所属区间,按照事先制定的策略表,进行微网的稳态功率调控。在实际工程应用中,合理地设计了功率控制的控制网络,保证控制的快速性和准确性。该控制方法实现了光伏、风电、蓄热锅炉的功率自动控制,提高了离网型微电网稳态"源-荷"平衡控制的准确性和鲁棒性。
There is a need to better match the source and load of an off grid micro grid and reduce the disadvantages of over reliance on prediction information of energy management.Based on the research and engineering practice of the SOC state change trend of an energy storage battery,a control strategy based on expert rules is adopted for different operation modes and scenarios,and the micro grid energy management system is fully utilized.Integrated data acquisition and processing ensures that energy management can not only control the stable power of the microgrid according to the range of the SOC,but also according to the strategy table.In practical engineering application,the control network of power control is designed reasonably to ensure the rapidity and accuracy of control.The control method achieves the power automatic control of photovoltaic,wind power and a heat storage boiler,and improves the accuracy and robustness of the off grid micro grid steady-state source load balance control.
