【摘要】：微電網(wǎng)通常采用儲能系統(tǒng)來平抑負載變化引起的直流母線功率波動。文章采用鋰電池和超級電容器的混合儲能系統(tǒng)(Li-SC HESS)來同時滿足因負載變化引起的功率與能量兩方面的需求。研究了混合儲能系統(tǒng)模型結(jié)構(gòu),提出了相應(yīng)的HESS功率協(xié)調(diào)分配的PCH強跟蹤控制方法。結(jié)合Simscape在Simulink中建立光儲微電網(wǎng)混合儲能系統(tǒng)仿真模型,與微電網(wǎng)常規(guī)的雙閉環(huán)線性控制策略進行對比研究。仿真試驗結(jié)果表明,提出的HESS控制策略可有效減少鋰電池充放電次數(shù),平滑其充放電過程,延長使用壽命,進而改善混合儲能系統(tǒng)的性能。
[Abstract]:Microgrid usually uses energy storage system to suppress DC bus power fluctuation caused by load change. Li-SC HESS, a hybrid energy storage system for lithium batteries and supercapacitors, is used to meet both the power and energy requirements caused by load changes. The model structure of hybrid energy storage system is studied, and a PCH strong tracking control method for coordinated power allocation of HESS is proposed. The simulation model of hybrid energy storage system of optical microgrid is established in Simulink by Simscape, and compared with the conventional double-closed-loop linear control strategy of micro-grid. The simulation results show that the proposed HESS control strategy can effectively reduce the charge and discharge times of lithium battery, smooth the charging and discharging process, prolong the service life, and improve the performance of hybrid energy storage system.
