Based on the topology of non-isolated DC-DC cascaded multi-level energy storage converters, analysis of working conditions and charging and discharging characteristics of super capacitors, a power distribution control strategy for non-isolated DC-DC cascaded multi-level energy storage converters is proposed.
In this way, a power distribution control strategy for the CHB energy storage system (ESS) is proposed. MATLAB/Simulink simulation results shows the accuracy and effectiveness of the proposed power distribution control strategy.
The energy storage converter in this paper is designed for the grid-connected charging and discharging process. For the charging process, in the blocking of the DC-DC link, the sub-module capacitor is uncontrollably charged to 650 V, and then is charged under the dual closed-loop control of the grid-connected Usm and Q.
In the direct parallel cascaded multilevel energy storage converter field, the dominant power distribution strategies are as follows: references [ 8, 9, 10, 11, 12] proposed a power balance strategy by sorting the super-capacitor voltage in one arm with step waveform modulation.
Although batteries (electrochemical ESSs) are proven options for most distribution network applications and have long lifetime and good efficiency, some options (e.g., NaS, Li-ion, NiCd, VRB, and ZnBr) are costly.
The “Energy Storage Medium” corresponds to any energy storage technology, including the energy conversion subsystem. For instance, a Battery Energy Storage Medium, as illustrated in Fig. 1, consists of batteries and a battery management system (BMS) which monitors and controls the charging and discharging processes of battery cells or modules.
