Power Coordinated Control of AC-DC Hybrid Microgrid Based on Subgrid and Energy Storage
摘要
Abstract
In order to solve the problem that a single energy storage form of AC/DC hybrid microgrid cannot meet the power coordination of all subgrids,a multi-mode power coordination control strategy considering the changes of interlinking interface converter(IIC)and hybrid energy storage state of charge(SOC)is proposed.According to the subgrid normalized voltage and frequency indexes,the microgrid operation domain is divided,combined with the power state of each subgrid and the hybrid energy storage SOC,the IIC and the energy storage bidirectional interface converter(BIC)cooperate in power transmission under different operating conditions,to realize the overall power balance of the system as well as to control the storage SOC within a reasonable range,which improves the stability and reliability of the system.At the same time,the hybrid energy storage formed by supercapacitor and battery can not only give full play to the advantage of rapid response of supercapacitor,but also reduce the impact of overshoot and overdischarge on the battery.Finally,the inter-network power mutual aid scenarios with different operating modes are designed in the PSCAD environment to verify the effectiveness of the multi-mode power coordination control strategy.关键词
