基于光储源荷供电微网的综合能量管理策略

Comprehensive Management Technology of Integrated Power Supply Microgrid Based on Optical Storage,Source and Load

在智能电网迅速发展以及分布式能源不断接入电网的背景下,电网和电力用户之间的互动更加频繁。针对现有配电网配电容量不足和末端电压跌落严重的问题,提出了一种基于光储源荷一体化的供电微电网和低压治理装置组合而成的系统,利用综合能量管理控制技术来实现多种能源之间的协调控制、电网容量扩容以及实现对分布式能源的消纳。最后,基于Matlab平台搭建了相应的仿真模型,验证了该模型在解决无功和谐波不平衡以及治理低电压方面的有效性。

With the rapid development of smart grid and the continuous access of distributed energy to the power grid,the interaction between power grid and power users is more frequent.Aiming at the problems of insufficient distribution capacity and serious terminal voltage drop of the existing distribution network,a system composed of power supply microgrid and low pressure treatment device based on the integration of light storage,source and load is proposed.The integrated energy management and control technology are used to realize the coordinated control between multiple energy sources,the expansion of power grid capacity and the consumption of distributed energy.Finally,the corresponding simulation model is built based on Matlab platform to verify the effectiveness of the model in solving reactive power and harmonic imbalance and controlling low voltage.
