【摘要】：將模塊化多電平變換器作為電池儲(chǔ)能裝置的并網(wǎng)變換器,可在平抑新能源輸出功率波動(dòng)的同時(shí)實(shí)現(xiàn)儲(chǔ)能裝置的直接并網(wǎng),降低了系統(tǒng)成本。對(duì)于大規(guī)模電池儲(chǔ)能裝置而言,如何延長其使用壽命一直是學(xué)術(shù)界和工業(yè)界的研究熱點(diǎn)�；诖�,提出了一種適用于儲(chǔ)能型模塊化多電平系統(tǒng)的多時(shí)間尺度控制方法。根據(jù)不同的時(shí)間尺度劃分,可將整體控制分為三層,并為每層控制設(shè)定了各自的控制目標(biāo)。在該控制方式下,僅需估算每個(gè)電池組的相對(duì)健康程度,即可確定各子模塊的輸出功率,進(jìn)而改善電池組的健康狀況,使其趨于一致,延長儲(chǔ)能系統(tǒng)的使用壽命。最后通過Matlab仿真和實(shí)驗(yàn)驗(yàn)證了該控制方法的有效性和可行性。
[Abstract]:The grid connected converter of modular multilevel converter for battery energy storage devices, can be directly connected to the energy storage device in the new energy to stabilize the fluctuation of output power at the same time, reduce the cost of the system. For the large scale battery energy storage device, how to prolong the service life of a straight is a hot research topic in academia and Industry Based on this, a method is presented for the storage of multiple time scale type modular multilevel control system. According to the different time scales, the overall control is divided into three layers, and each layer of control set control objectives respectively. In the control mode, only a relatively healthy degree estimates for each battery, you can determine the output power of each module, and then improve battery health, make it consistent, prolong the service life of the energy storage system. Finally, through Matlab simulation and experimental verification of the The effectiveness and feasibility of the control method.
