Abstract

Solid-state transformer (SST) could be a solution for a future distribution system, in which many renewable energy sources (RES) are integrated. The SST consists of a single-phase dual-active bridge (DAB) converter, which is scale-down the dc voltage level. The control objective of the DAB converter used in the SST is to control its output voltage. This control strategy consists of a proportional-integral (PI) controller and a single-phase shift (SPS) modulation. Numerous literatures have mentioned about the SPS modulation for the DAB converter. However, they do not provide procedures in implementing the SPS modulation in the real controller. This paper aims to develop the SPS modulation in the real controller of the STM32F446RE microcontroller. The proposed SPS modulation is based on a master-slave timer feature, which is available in the STM32 microcontroller. The development process and testing of the complete control strategy of the DAB converter were carried out in the hardware-in-the-loop (HIL) simulation using Typhoon HIL. This scheme speeds up the development of process and reduces the costs. The experiment in the HIL environment shows that proposed control strategy of the DAB converter consisting of the PI controller and the SPS modulation is successfully implemented in the real microcontroller of the STM32F446RE. The proposed control strategy of the DAB converter is capable of bidirectional power flow, which is useful for integrating distributed generators in the load side. Moreover, this control strategy can reject the disturbance caused by loads.

Abstract

The integration of photovoltaic (PV) generation into power systems presents operational challenges due to the temporal mismatch between daytime solar production and nighttime peak demand. This issue is particularly critical in tropical systems with limited local generation flexibility, such as Guluk-Guluk, Madura, where a PV–battery energy storage system (PV-BESS) is planned to support nighttime peak load demand. This study aimed to determine the optimal PV-BESS capacity configuration under a PV-only charging scheme, in which the battery is charged solely by PV generation without grid support. A 25-year time-series simulation based on historical solar resource data was integrated with Particle Swarm Optimization (PSO) to minimize the Net Present Cost (NPC) while penalizing unmet energy demand. Battery degradation was modeled using calendar and cycle aging, and the impact of Power Conversion System (PCS) charging capacity was evaluated through sensitivity analysis and re-optimization. The baseline optimal configuration consisted of 75.36 MWp of PV capacity and 570.98 MWh of initial BESS capacity with a 50 MW PCS, achieving 83.85% reliability and an NPC of USD 269.18 million. The results indicated that battery aging was not the dominant factor limiting system reliability; instead, daily solar variability and PCS charging constraints had stronger impacts. Increasing PCS capacity from 50 MW to approximately 56 MW significantly improved reliability, while further increases yielded diminishing returns as the system transitioned from power-limited to energy-limited operation. These findings emphasize the importance of integrated PV, BESS, and PCS planning for renewable peaker applications in tropical power systems.
