摘要
在交直流混合微网的应用中,可再生能源的发电具有不确定性,而储能系统在充放电能进行调控的同时也会造成相应的寿命损耗,这些问题严重影响了微电网的经济性。针对上述问题,提出了一种交直流混合微网双组储能控制策略。在混合微网中将蓄电池组划分为单向充电组和双向调度组,储能分组进行充放电,减少可再生能源不确定性对微网经济性的影响,同时降低储能寿命的损耗。基于MATLAB仿真平台建立了交直流混合微网调度模型,仿真分析并验证了该策略的合理性和有效性。
In the application of AC/DC hybrid microgrid,the generation of renewable energy is uncertain,and the energy storage system causes corresponding life loss during charging and discharging,which seriously affects the economy of microgrid.To solve the above problems,the article proposed a dual-group energy storage control strategy for AC/DC hybrid microgrid.The battery was divided into one-way charging group and two-way dispatching group,and energy storage was grouped for charging and discharging,which reduced the impact of renewable energy uncertainty on the microgrid economy and reduced the loss of energy storage life.Finally,a simulation model of AC/DC hybrid microgrid was built in MATLAB.The simulation results verify the effectiveness of the proposed strategy.
