Abstract EN
This paper presents an evaluation of an optimal DC bus voltage regulation strategy for grid-connected photovoltaic (PV) system with battery energy storage (BES).
The BES is connected to the PV system DC bus using a DC/DC buck-boost converter.
The converter facilitates the BES power charge/discharge to compensate for the DC bus voltage deviation during severe disturbance conditions.
In this way, the regulation of DC bus voltage of the PV/BES system can be enhanced as compared to the conventional regulation that is solely based on the voltage-sourced converter (VSC).
For the grid side VSC (G-VSC), two control methods, namely, the voltage-mode and current-mode controls, are applied.
For control parameter optimization, the simplex optimization technique is applied for the G-VSC voltage- and current-mode controls, including the BES DC/DC buck-boost converter controllers.
A new set of optimized parameters are obtained for each of the power converters for comparison purposes.
The PSCAD/EMTDC-based simulation case studies are presented to evaluate the performance of the proposed optimized control scheme in comparison to the conventional methods.
