摘要
在目前的新能源发电与微电网系统中,传统的能量型储能器件由于频繁功率波动,往往会大幅削减蓄电池寿命。针对这个问题,本文采用超级电容与蓄电池共同放电维持直流母线稳定,并针对性的提出低通功率前馈方法,达到分配超级电容与蓄电池之间功率流动电能目的。同时搭建相应的数学模型进行进一步分析验证算法。
In the current new energy power generation and Microgrid systems, the traditional energy storage devices often slash battery life due to frequent power fluctuations. In order to solve this problem, this paper uses the joint discharge of supercapacitor and battery to maintain the stability of the DC bus, and puts forward the low pass power feedforward method aiming at the purpose of distributing the power flow power between the supercapacitor and the battery. At the same time, the corresponding mathematical model is built to further analyze and verify the algorithm.
